We build some Sulphur trailers out of aluminum.  We would need specs and other information. Please feel free to contact our Heil Texas facility for more information (817.430.1472 ). Thank you for the question.

To ensure proper weight distribution and axle load limits, lift axle ride bag pressures should be set by placing the loaded trailer on a scale and dialing in the ride bag pressure to the legal axle weight limit. The loaded trailer will need to be scaled axle by axle to arrive at an accurate per axle trailer weight. Using a calibrated scale the user can correlate the ride back pressure to the gauge pressure. It is incumbent upon the user to ensure he/she is in compliance with all state and federal regulations.

The British use the same API (American Petroleum Institute) bottom loading valve size as we do under DOT 406. This is in accordance with API RP1004 for total interchangeability with all loading valves used for petroleum liquids. Thank you for your question.

Hello Rick,
Unfortunately we do not have a recommended procedure for cleaning the inside of the trailer. However, I do believe in this situation the aerator itself has come loose and the internal wear pad has rotated inside. We recommend hand tightening the aerators once a week to help prevent the wear pad from turning. At this point you will need to drop the line, discharge valve and loosen the aerator. Then you need to reach up inside the tank and turn the wear pad to its original location. Finally hand tighten the aerator, reinstall valve and piping. Thanks for the question.

Eric, we strongly recommend lining any tank hauling crude, even sweet. If they acidize frac the well, you will get some acid when you pull loads of crude afterward. It will lay on the bottom of the tank and can start pitting rapidly. We have seen this happen on several occasions.  H2S mixed w/ water can start a problem quickly. Thanks for your question.

Glenn, since 1990 there have been revisions to mounting fenders as well as changes to the cabinet mounting, depending on the type and size of the cabinets. Without seeing your trailers to determine the type of fenders / cabinets, it would be difficult to recommend replacements or repairs. If you can tell us your location we can most likely have one of our distributors call you. They can look over the trailers to determine what can be done. Your Heil Regional Distributor or Heil Regional Sales Manager will also be able to either sell you the parts or tell you where they can be purchased most conveniently by you. Please let us know your location and we will assist you in solving your problem.
  

Heil Trailer International does not rank tank manufacturers, and we know of no source for such a rating. We respect our competitors for the niche they fill and do not consider their market position when designing our products. However, Heil is the only ISO 9001 certified tank manufacturer in the United States, and therefore held to strict quality standards, which includes custom designed and manufactured trailers. Each order our plant accepts for production is individually engineered per detailed sales specifications in conformance with governing regulations and Heil’s “best-in-class” quality standards. We offer a full line of products in each of the segments (liquid, dry bulk, heavy haul, etc.) we serve, for virtually any axle configuration in order to comply with State and Federal Bridge formulae (as well as international standards). Heil uses the highest quality components and raw materials during their manufacturing processes. A typical Heil owner believes safety, ergonomics, equipment longevity, low maintenance costs, superior technical support and service, high resell value, and aesthetics are the most important features when picking an equipment supplier. Heil strives to meet this “best-in-class” quality standard in an effort to exceed our customer’s expectations. We hope this answers your question. If you’d like to learn more about Heil Trailer International, please contact your nearest authorized Heil Trailer International distributor found on our web site.  

This is a very good question. We had to turn to our Heil Trailer International Canadian Distributor (Intrans-Corp, Ph: 218-829-6136, Cell: 320-412-6521, intrans@hughes.net) to get an answer. To the best of our knowledge, their is no specific fall protection requirements. There are however, some general safety requirements such as "no platform can be any higher than the overturn protection" but, these are basic government safety regulations that trailer manufacturers have been required to follow for a very long time and just about any trailer will have this incorporated or just will not have any type of catwalk/walkway. What we have found is that most companies both trucking and shipping have their own requirements as to what their fall protection policy is going to be in accordance to their safety department and insurance company requirements. This means if you are moving product for Ecana or Shell your trailer has to meet their safety regulations which would include fall protection. Our suggestion is that you discuss with your company and the company you are hauling product for and ask them what are their current safety / fall protection requirements. 
 

Generally stainless steel general chemical insulated tank trailers (MC307 or DOT407) are equipped with a heat panel. The heat system design uses either a dimple or channel panel. The heat panels are designed for steam (up to 150 psig) and tractor in-transit heat (3.5 to 6 GPM at no more than 10 psig). Steam is usually connected at the rear of the trailer and in-transit is at the front of trailer. Some carriers have designed stationary heating systems for use with a parked trailer. The stationary heater is similar to a home water heater with a pump and closed loop system. The water heater tank contains the same coolant as the tractor. The coolant is pumped to the heat panel and returns to the water heater. The connections at the front of the trailer would be used with the stationary heater. When using in-transit, the tractor coolant is temperature is approximately 175 deg F to 200 deg F based on the specific tractor. Several precautions should be taken with heating. Always make sure the heat panel is filled with coolant if using in-transit heat. Never heat/steam an empty trailer. When you steam a trailer you will loose your coolant. If using a stationary heater, minimize the hose length from the heater to the trailer, make sure the closed loop system is fully charged with coolant and monitor the circulating coolant temperature.
 

Gasoline is delivered globally in steel trailers. India, Latin America, Brazil and others are exclusive. It is compatible. Local laws might suggest different for you The US and the rest of North America (and Europe) shifted primarily for reasons of weight (among others).  

Thanks for the question, Don. Aluminum brightener removes all surface contaminates and also dulls the finish. The only way to restore the finish is to repolish the unit. If you need any help with this Heil Tank Service in Louisville, KY offers this service. You can contact the head of our Polishing Services Dept, Vince Lombardi, at 423-774-3250. Vince will be able to answer any questions you may have about polish. 

Sorry Mike, we are unaware of any such permit. You should contact the DOT and see if they can be of more assistance.  Thank you for the question. 

Dave, there is no quick way to do this. If a trailer is allowed to build up hardened cement on the inside you are limited to chipping and scraping the material out. We would advise removing the piping to avoid contamination of future loads. 

Hi Richard, assuming you are speaking of a Heil petroleum trailer, it is not recommended to cut holes in the flashing rails of any size. However, Heil has brackets for this purpose. These brackets are designed to be tack welded to the flashing rails. Please contact Heil Tank Service for these parts. 
 

Thanks for the question Rod. There is generally no "code". We build per specification (specially pressure rating), per TTMA recommended practice and per any applicable road laws both federal and state.
 

Thanks for the question Ken. Yes you can haul Crude oil in 306-406 tanks as long as the vapor pressure does not exceed the design pressure of the trailer. Most Crude Trailers being built today in the US and Canada are 407 Spec. Basically the same as other petroleum tankers, the requirements for a tanker hauling crude is based on flash point and vapor pressure.  Some crude can be hauled in non DOT tanks but is usually not done due to the versatility needed to haul all crude product, ranging from heavy crude all the way to condensate.  This is the reason why DOT 407 is usually used for crude.

 

Thanks for the question Dirk!  No, you cannot turn a 407 into a 412 certification. A 412 trailer has to be built to that certification; it must  be built to ASME code and carry a U-Stamp on the plate.  Unlike the 407, all material that goes into the 412 vessel must have papers certifying it meets the proper specifications. The trailer must also be rubber lined to handle hydrochloric acid. Even though some of these trailers are aluminum, the majority of them are made of steel.

 

Sure, this was a milk tank (usually stainless steel). The 5400 was for 5,400 gallons (probably a two compartment trailer), and the FPU stands for "farm pick up".  These tanks were / are used to collect the milk at the farms and take it to the dairy for processing. They also usually have a two or a three section stainless steel cabinet at the rear of the trailer that houses the valves and piping, the stainless steel sanitary pump and motor, and a "sample chest".

 

By design, when the tractor brakes are set the trailer brakes will set automatically. This is done to ensure a safe work area is maintained; hence, it is important to leave the trailer brakes set during the loading and unloading process. This prevents the trailer from shifting fore or aft as product is being loaded or unloaded from the trailer.  The actuation of the trailer brakes has no relationship to the operation of the trailer.

 

You can contact Shane Jenkins at Emergency Response Services, Inc. (256-997-9087 Business;
423-506-6624 Cell; 256-997-9041 Fax).  He will do on site training.

 

Thanks for your question.  You will want a 407 tanker with insulation and possibly in transit heating capability depending on the length of your haul and outside air temperature.  This is to prevent the Bio-Diesel from solidifying.  For the pros and cons of 406 and 407 tankers, please refer to the simple table below:

Tank Type	406	407
Products Carried	gasoline, fuel oil, alcohol	solvents, plasticizers, casinghead gas
Product Density (lbs/gal)	6.1 to 7.2	7 to 13
Tank Pressure Rating              (MAWP) (psig)	3.3	25
Insulation	rarely           insulated	insulated & noninsulated
Tank Shape	Elliptical  Double tapered or straight elliptical	Straight cylindrical or double conical

Hi Bill.  The thickness of Heil trailers is dependent on the area of the tank measured. Generally our hoppers are constructed with 0.204" upper sections, 0.325" heavy hoppers (where the sub-frame attaches) and 0.250" lower cones. The sides are 0.186" and the tops / end cones are made 0.204" thick. Based on the measurement you provided us, your trailer has a 40% wear. We feel you should be concerned with any trailer with 30% wear or higher. Feel free to contact The Jack Olsta Co., the Heil dealer in your area, at 888.907.7940 for more information. Thank you for your question!

Thanks for your question.  We dont know of any law, but it is a recommended practice to have a trailer cleaned and provide a cleaning slip along with the MSD (Material Safety Data) sheet of the last product hauled.  This is done as a safety issue.  Most of our dealers will not purchase a used trailer that has not been cleaned, unless it is a petroleum trailer or a Dry Bulk trailer that hauls cement or some other "dirty" product. If it has been cleaned (typically a chemical trailer) most dealers will want a cleaning certificate. You should contact anyone of our Heil distributors; they may be interested in purchasing it.

Hi William.  Yes, our Kalyn Siebert plant still manufactures extendible double drop trailers.  Please contact Wesley Chandler, Director of Sales, at 254.865.7235 for any product inquiries.  Thank you. 

Hi Robert and thanks for the question.  More than likely, the brand of the overfill system is Liquidometer, which unfortunately is no longer available nor is there a probe compatible.  I would recommend you install a whole new system.  Any of our distributors can assist you with this install after providing certain information about your trailer.  We must know the number of compartments and if the system is equipped with top probes only or top and retain probes.  Please visit the zip code locater on the left-hand side of our sites home page to locate the dealer near you.  

Thank you for your question, Yissachar.  Regarding hauling different types of food products, they all can be transported in the same container as along as there is a sanitary wash between loads to prevent cross contamination.  The only change to this occurs when you are transporting grade-A milk, which needs to be in a 3-A standard container.  This means it must include a sanitary valve, vent and manhole; it also requires a #4 finish interior shell.  Most food grade barrels are type 304 stainless. If you have more detailed questions or require a quote on this type of equipment, please contact Stuart Tank at 262-723-2200 and ask for Mike ODonnell.  He'll be glad to help.

Thanks for your follow up question TR.  There certainly is such a system - it's called "The Tradecounter System" and acts just as you describe.  The system is preset to a weight and the up axle comes down when the predetermined weight on the down axle is achieved.

Thank you for your question.  In the U.S. welding quality evaluation methods are developed by the AWS (American Welding Society).  Their test methods are then incorporated by reference into standards such as ASME (American Society of Mechanical Engineers) and AISC (American Institute of Steel Construction), as well as others.  In Europe, for Petroleum tanks they use standard EN12972 for Testing and Inspection.  The details regarding testing and welding inspection can be found in Sections 4 and 5 of the standard.  An example of the requirement includes: the weld seam factor must be 0.8 for the barrel construction and 10% of the total amount of circular and longitudinal seams must be inspected, and all cross joints must be inspected (X-ray is more common but ultrasound NDT is also possible).

Thank you for your question. If the unloading site has a rear downward slope and the tank in question is a straight bottom tank with the tractor in the uphill position, the slope of the unloading site enhances the designed slope of the trailer (a straight bottom trailer typically has 2 - 3 degrees of downward slope from front to rear).
However, the operator should be cautious that the slope of the unloading site is not too great, hence negating the slope of the discharge pipe from the sump to the bottom loading / unloading area. In this scenario, residual fuel could remain in the discharge pipe of the aft most compartments. You could have similar problems with double tapered tanks at steep sloped sites as well.
Given the many different slopes and slants of offloading sites and possible trailer configurations, Id have to agree with your customer. The best way to ensure optimum drainage is to unload level, or as close to it as possible.
One final point, the trailers bottom construction style plays a large role in tank drainage; trough bottom trailers can sometimes outperform tapered designed trailers. We have film and additional information if you are interested. Just contact your nearest Heil Distributor.

Good question and a timely one at that with the interest in ethanol today.  There are two types of ethanol hauls; one from the distilling location and one from the blending location. The distilling location would probably require a single compartment, dedicated trailer although a multi-compartment trailer may work as well.  The blending location would require a multi-compartment trailer.  In either case, an aluminum elliptical petroleum trailer (DOT-406 Code) would meet all the regulated requirements for ethanol.  If you convert a petroleum trailer to an ethanol trailer, you should replace the Cork/Buna gaskets with either Viton or tef-o-sil.  

Thanks for your question Bill.  Please go to our web site home page (www.heiltrailer.com) and use our dealer search (just input your zip code) to locate your nearest Heil Authorized Dealer.  They will be able to access hundreds of used trailer equipment sources and help you locate the trailers you need.  You should also contact our Sales Agent responsible for Central America, Mr. Frank Schnabel (Costa Rica 011-506-823-6773).  He can help you locate the equipment and ensure you have the proper trailer design and specifications for that region of the world.
  

Thanks for the question.  Technically, our chief engineer considers all elliptical shaped tanks (the industry standard for petroleum trailers) NOT capable of obtaining a negative pressure.  To protect against any damage that may occur if a vacuum is pulled, all Heil DOT 406 cargo tanks (petroleum trailers) are provided with an inbreathing vent installed within the vapor system.  This is required by the regulations.

This can be designed and built easily.  Typically, we sell a trailer configured with 9500 gallons (nominal) with these compartment sizes: 3000 / 2000 / 1500 / 3000 for Wisconsin.  However, the compartment sizes you have described above nominally for the actual compartment loads can be achieved.  If you are interested, please contact our dealer in Elkhorn, WI, Stuart Tank Sales (262-723-2200).  They have stock units in the schedule later this year that could be easily changed to meet your specification.  Thanks for your question.
  

Thank you for your question.  We build all our petroleum trailers in Argentina from this material and it is perfectly compatible with jet fuel (or ATF).  Aluminum Alloy XTRAL 728 is a 5000 series aluminum magnesium alloy for chemical composition and mechanical properties you should request information from the aluminum association.  For your information, Alcan (formerly Pechiney) achieved Aluminum Alloy XTRAL 728 certification (for use with jet fuel (or ATF) in 2003 from the German Government and the office of the TV.   Many German tank trailer manufacturers use this alloy for this very purpose.  The certification office in France has also approved the use of this alloy with jet fuel.  
  

Larry, There are many solutions to OSHA compliant fall prevention / protection requirements.  Although this is not a direct endorsement and there are other solutions, Heil installs a fall protection system marketed by the trade name Standfast. It is a system developed in Australia, but is used world wide. Please check out their site http://www.standfastusa.com.

 

Thank you for the question, Denis.  Yes there is such a thing as a heated tank trailer.  Heil builds an aluminum non-code tank with steam coils mounted on the outside of the vessel, on the belly of the tank.  Another method used by the competition is heat panels, typically used on stainless trailers, mounted in the same place.

 

Hi Tim.  Yes, this is possible.  It is a combination of adding a liftable suspension/axle and controlling it with the tradecounter option.  It is applicable to one axle on a tandem or several axles on a multi-axle arrangement.  On a 10,000 gallon 4 compartment trailer, it adds approximately 400 lbs. Thank you for the question.

Thanks for your question Greg.  Actually the reply to this question is too complex to provide based on the given information and depends on many factors, the first of which is the product.  Two other factors you should take note of are the type of material the container is constructed of and the environmental conditions during the loading and unloading procedures.  Id like to refer you to the Code of Federal Regulations www.access.gpo.gov/nara/cfr/cfr-table-search.html so you can explore the answer more thoroughly for your Best Practices Manual. Good luck and be safe.

 

Hi and thank you for the opportunity to explain some of the ways in which Heil excels for our customers.  There are many important components for you to consider before purchasing a pneumatic trailer (cementer) some of which are the operating pressure the trailer can withstand, strut design, and the type of trailer suspension.  Heil offers a 25 psi rated tank -- the Super Jet Cementer is designed and built structurally to operate at 25 psi. This allows faster unloading.  The Cementer is hydro-tested at 37.5 psi or 1.5 times normal operating pressure. Heil stamps their data plate with this actual test pressure.  The competition normally stamps their data plate 18 psi.  Secondly, Heil is on its fourth generation strut design the results of twenty years of continuous improvement. This is the most critical area on the tank trailer due to stress and should be designed with safety first and foremost. Our trailers have a bottle pin construction that attaches the vessel to the trailer frame to ensure flexibility and reduce stress (many of our competitors weld their struts into place).  Finally, Heil trailers use Hendrickson suspensions.  In fact, Heil and Hendrickson combine their knowledge and experience to design the suspension around the pneumatic trailers operating conditions during loading, unloading, and transitions. Because of the working relationship between Heil and Hendrickson, the customer will enjoy the best trailer and suspension combination in the industry today.  To contact a Heil dealer near you, please call our customer service department at 800.400.6913.  Heil has an expert dealer network available to help you find the answers to further questions, the right trailer / tractor combination, and after market parts and service.

Thanks for your question from China.  The price of a typical petroleum trailer is $80,000 USD + depending on size, suspension, and other specifications.  You also need to factor in freight, any applicable duties, insurance, etc. Heil builds their trailers out of light weight aluminum so you can haul more product when limited by a gross vehicle weight.  Finally, you should be familiar with DOT-406 and ADR regulations.

Thanks for your question on 2 bar tanks.  Yes, most of Europe unloads at 2 bar (~ 30 psi) and the infrastructure is set up for it.  Since unloading rates are directly related to unload pressure, increasing pressure reduces off-load times.  However, in the US more than 15psi is unusual and few bag houses are able or willing to accept 2 bar or anything over 15psi.  Therefore, a 2 bar tank will not be utilized in most US facilities until the total deliver system is upgraded to accept 2 bar.

Thank you for your excellent question Brian. You asked a two part question, and I'd like to answer the second part first.  The gasket material we most often use is nitrile (you should confirm your trailers are spec'd with nitrile gaskets, your maintenance people should know) and it is probably the most cost effective material for petroleum trailers on the market.  Nitrile is made up of two polymers butadiene and acrylonitrile and it is the acrylonitrile that gives nitrile its strong resistance to petroleum products.  However, nitrile does not do well when exposed to ozone and sunlight and most manufacturers only give a 12 month shelf life for the material.  Most gaskets on the trailer are not exposed to sunlight but they are exposed to ozone.  When the gaskets are "wet" the petroleum prevents the ozone from attacking the material; however, after a trailer sits idle for a while, the petroleum evaporates from the seal and allows the ozone to attack the seal.  So "yes" the theory of "drying out of gaskets" is correct.

Now I'll address the first part of your question.  If your trailers are several years old, then replacing the seals in your pipe couplings and the gaskets between flanges should give you several more years of trouble free service. These parts can be obtained from any Heil Tank Service facility (see our web site:  www.heiltrailer.com for contact information).  I hope that I've been able to help.  Best of luck! 

Thanks for your question. Cement trailers are notorious for looking dull after a year in service so I understand your desire to polish the tank. The aluminum cleaner you applied is an acid. Acids clean aluminum very well and because of that, they are used to prepare aluminum for polishing. Acid will etch the surface and will absolutely destroy a polished finish. Once you polish aluminum you can only use a neutral soap with a pH in the range of 7 to 10 (see our Q&A on how to wash a polished trailer listed earlier on the web site).

Heil Trailer International has a polishing service and now distributes Nuvite polishing compounds -- used in all of our manufacturing and Heil Tank Service facilities and recommended for the polishing of aluminum tank trailers such as yours. I recommend you contact Heil's Director of Polishing Services, Vince Lombardi, he may be able to help you restore your trailer to that original shine.  Vince can be reached at 423-745-5830 (Cell  423-774-3250).  Good luck!.

The pressure inside the vessel is relatively constant across the entire surface area so there is 14.7 psi on the lid of the tank as well.  Thank you for your question

Hi Rick!  First of all thank you for the question.  We cannot be sure of the exact numbers; however, based on industry estimates, we believe there are approximately 30,000 tank trailers operating in the U.S. today.  Of these 30,000 trailers, we further believe that Heil Trailer International is the leading brand in the marketplace.

This is a great question and one we get frequently.  This is the process Heil recommends for washing polished trailers:

1. Start by using a pressure washer to remove the top layer of soil, keep the surface wet and cool.  Never put soap on a hot dry trailer. If at all possible wash the trailer when the metal is cool, not in the heat of the day.
 
2. Always use a neutral soap. This would be a soap with a pH level as close to seven (7) as possible. Anything below a seven (7) is an acid, which you should never use on a polished trailer. A number above seven (7) is an alkaline, and the higher the number the more caustic to the metal.  We recommend that you use soap with a pH between seven (7) and ten (10).  For example, Zep Manufacturing's red powder soap 4358 will work well for cleaning polished aluminum.  This soap contains emulsifiers to lift the dirt without harming the finish and has sufficient wetting agents to keep the surface from drying too quickly.  Be sure to follow the dilution instructions on the packaging.  If you choose a different soap, check with your safety representative and the soap's MSDS to ensure the pH level is within the acceptable range and that it is safe for polished aluminum.  We cannot stress the importance of using the correct soap, as the wrong chemical can damage the surface instantly.  Also, use a soft bristle brush made for truck washing.
 
3. Washing Procedures: Always start at the bottom and work your way up to the top of the tank.  This allows the water to constantly flow towards the bottom of the vessel, keeping the tank wet. Complete a four to six foot section at a time (or as much as you can without the soap drying on the trailer).  You may need to make adjustments to the size of the sections dependent upon the climate.  Finally, rinse the trailer thoroughly.  Ninety percent of trailer streaking is due to soap residue. Even if there are no suds, make certain that the soap has been completely rinsed.

Arthur, first of all - thanks for your question, Heil UK offices will be in contact with you shortly.  When is it best for them to call and where?  Your question prompted a Go to Market "Single Point of Contact" review by our parts division. Recognizing the need to make our website more convenient for our customers, we will develop a "Who Do I Contact" component in the near future.

Thanks for your question Tim. This is legal and common for jet fuel, diesel, and in some cases, home heating oil. For home heating oil, large single compartment trailers move product from the rack (and occasionally from a barge) to a jobbers storage tank. Then the home heating oil jobber typically delivers the oil to homes by ten-wheeler (sometimes six-wheeler) straight trucks.
The only requirements for single compartment trailers (other than not exceeding the GVW) are that the tank must have enough venting capacity which is dependent on the size of the compartment or tank, and the barrel/vessel must have DOT defined structural support. This typically consists of an internal baffle or external ring.  Heil has built many single compartment home heating oil trailers for the Northeast. Learn more about these types of trailers in our product catalog on this website.

 

This is a good question. There is no standard based on our experience across North America. Rates can be per ton, per mile, a combination of both, fixed rates for dedicated service, etc. There are also variables to such rates: surcharges for fuel, for wait/idle time, etc.

Hi Everette,
Please contact our Heil Tank Service representative at email address: wstapleton@Heiltrailer.com for a calibration chart. Be sure to include the VIN number so he can look up the appropriate chart.
Thanks for your question.

Hello Mr. Cheah,
Thank you for your question. I recommend you start your search with our website in the North American portal. Familiarize yourself with the specifications and terminology listed in the Product Category (under) - the Petroleum specifications are fairly standard around the world, with some exceptions. Next Id move to our Asia/Australia portal and review the trailers that serve the Thailand/Malaysian markets (the portal menu is on the left side of the home page). It would also be beneficial to visit your customers that haul petroleum so you can become familiar with their operation and specific needs. I hope my advice has helped - good luck at Norgren.

When rollover stability systems hit the market a few years ago, the initial investment in the technology, as well as the service and periodic maintenance, was very expensive. As the engineer of these systems gained market experience from deployed systems, the price of the technology began to fall and the reliability of the electronics increased. Today, an OEM can install a rollover stability system for less than $1500 on a tandem suspension. Given the potential liability of a rollover, this is a great investment. When compared to the effectiveness of lowering the CG of a trailer within the allowable envelope, the benefits of a rollover system far outweigh the 1-2 mph increase in rollover speed protection.
Specifically, this means an electronic rollover protection system proactively manages the speed at which your equipment is operated in a rollover condition. As the system senses a potential rollover, brakes are systematically applied to decelerate the trailer out of this condition. An LCG (low center of gravity) designed trailer provides passive rollover management (i.e., drivers must conscientious decide to drive slower than the increased rollover speed LCG trailers provide). Although LCG trailers provide a slightly higher rollover speed, that can be thwarted by a trained driver, using poor driving habits, exceeding that safe speed.

 

Our laws require that these vapors be collected or recycled throughout the petroleum transportation and logistics channels. When a tank trailer drops gasoline or diesel at a gas station, the vapors in the underground tank are pushed out of the ground and into the tank trailer. Conversely, when the same trailer goes to the terminal to reload, those vapors are pushed out of the trailer and collected into a storage tank.

 

Thank you for your question Tom. Unfortunately, Heil Trailer International does not build this type of specialized trailer - a refrigerated vessel that is EXTREMELY complicated! Please contact West-Mark located in Ceres, CA - they may be able to help you.

Heil remains neutral on disc brakes - we are neither for nor against. However, we readily install them upon customer request and believe they will become a popular option in the near future. Id also like to point out that if the Department of Transportation shortens the required stopping distances on Class 8 vehicles, disc brakes are the only viable options for achieving the shorter stopping distances at this time.

Once these are met, the techniques you've learned can be applied.

I certainly can - we have done a lot of business in Saudi Arabia over the years so we know exactly the type of unit you need. I recommend you contact our Regional Manager for that part of the world - Mr. Salauddin Mohammed (smohammed@heiltrailer.com). He can be reached at (USA) 770-517-2993. Good luck in your quest.

 

We believe the likely hood is low based on the current feedback we have received from the Government and interested parties. Heil's position remains unchanged we are neither an advocate nor an opponent of the wetlines purging system and we stand ready to serve the industry in either capacity based on the direction the Government dictates.

 

Thanks for asking the question. One of the benefits our customers gain from working with Heil is access to the best ideas and practices in tank trailer design and operation from around the world. We have designed and built both food grade and blended oil trailers with agitation systems at Heils plant in Argentina. For more information on this specialized trailer, please contact jcalonge@heiltrailer.com.

This is not something that is normally done on (or recommended for) a petroleum trailer. Id research the possibility of some sort of custom designed intransit heat system that runs off of the tractos radiator/cooling system (steam coils or radiator type system). In addition, this should be wrapped with insulation and a thin aluminum or stainless steel jacket.

 

The GVWR - gross vehicle weight rating is how much weight your vehicle is designed to carry. The GVWR includes the net weight of the vehicle (or trailer), plus the weight of the driver or passengers, fuel, cargo and any accessories added to the vehicle after purchase. This includes installation of a tag axle which affects your GVWR and cargo or payload capacity. The GVWR is a safety standard used to prevent overloading.

 

To the best of my knowledge, current tank manufacturing and construction standards meet new Ultra Low Sulphur Diesel (ULSD) packaging and transportation requirements. So as far as Heil is concerned, there is no truth to that rumor. However, many carriers are leaning towards dedicated compartments or dedicated hauls which may mean an increase in demand for new tanks.

Yes it does.

HM 183 was the docket number that was given to the legislation when it introduced Hazardous Materials bill number 183. I would name your files by CFR section such as CFR 49 178. CFR 180 etc. There is a sections that covers each code (DOT-406, 407, MC-312, etc). I hope this helps.

 

Thank you for your question. This is a challenge our industry faces every day - optimizing the weight of a petroleum (or dry bulk) trailer based on payload requirements, while considering the operating conditions, tractor weight, the state and/or federal weight law restrictions, and safety standards.
First of all, tare weight is the weight of the trailer alone, no payload or tractor weights are included. There are many different weight reducing options available for Heil petroleum trailers, from lighter duty barrel construction options to aluminum wheels, and Super Single tires. All reduce weight, but you must consider your operating conditions, payload requirements, and gross vehicle weight restrictions before going with a light weight option.
The best tip I can give you is to contact your nearest Heil Trailer International distributor. He or she can be found on this web site using the dealer locator function on the home page. Just type in your zip code and the nearest dealer will be listed by Product Category. Each and every Heil dealer is a product expert for their region and is readily available to help you specify equipment (including the lightest petroleum trailer possible) to meet your needs.

 

Farm pick up trailers have not been built by Heil in many years. However, we have distributors who were in the repair and service business during that time and have repaired those trailers over the years. The shop that probably has the most experience with this type of rebuild/repair would be Stuart Tank Sales in Elkhorn Wisconsin (262) 723.2200 or stuarttank@elknet.net  good luck!

We have many Heil approved service centers, dealers, and company owned shops (Heil Tank Service) located around the country (in all states) ready to assist you with repairs, parts, and technical service. To locate a shop near you, contact one of our technical service managers at 800-400-6913 (x574 or x353).

 

That is a good question and one that Heil Program Engineering Team answered on its test pad this year. The laws of physics define that only height, surface area (or surface friction), and the area of an outlet affect flow rate. After constructing a test vessel consisting of two twenty-five hundred and fifty (2250) gallon compartments, one built with a trough bottom, and the other built with a taper, our engineers confirmed what physics proved years ago. Since both compartments had nearly identical heights above the ground, surface area, and outlet area, both compartments drained completely within seconds of each other. The entire test is documented on DVD if you are interested in the experiment (just contact a Heil Rep for a copy). To ensure complete drainage and improve your unloading time, Id consider a trough system and larger piping and emergency valves. Please contact your nearest Heil representative for a complete explanation and set of options that will enable you to maximize your performance.

 

Thank you for your questions your timing is perfect. The Heil team has been working with the Major Oil Companies and their contract haulers on both questions. First, the tank trailer design is just one of the important links in the fuel transportation chain: the others being the ocean borne tankers, pipelines, and storage tanks. To ensure the trailer design link stays strong during the transition next year, Heil has gathered market intelligence and performed tests on existing designs. The majority of the carriers we've interviewed believe their existing designs are more than sufficient to safely and efficiently deliver ULSD fuel. Their number one concern is preventing contamination by ensuring complete drainage, which may require adopting new unloading procedures. Research indicates one-fourth (1/4) gallon of high sulfur diesel (3400 ppm) would contaminate 1000 gallons of ULSD (14 ppm). So it is imperative operators completely unload fuel from compartments, piping, and valves if mixing loads during deliveries.
In an effort to spread the word, Heil has gone the extra mile educating carriers with surveys and informative handouts ensuring they understand that product retention is a function of trailer slope, dependent on delivery site conditions. Designs like the double taper and trough bottom trailer can enhance drainage as long as they work with the slope of the terrain. The steeper the slope, the faster and more complete the drainage. We have found given equal terrain conditions, the trough generates as much if not more slope than the double taper design. For example, the Heil trough system generates 5% slope (over 4 of drop per compartment), which is enough to overcome a tractor-trailer incline. Neither the double taper nor straight bottom designed trailer can claim that performance. To ensure your link in the chain remains strong, make sure your operators are aware of the terrain and know how to take advantage of their trailer design to ensure complete drainage.
