Question: Hello, I am working in a Company that require trails for liquid sulfur (T=140°C) of 30 tons capacity. Can HEIL supply this requirement? Best Regard - Ana

We build some Sulphur trailers out of aluminum. We would need specs and other information. Please feel free to contact Erman Jackson at our Heil Texas facility for more information (817.430.1472 ext 276). Thank you for the question.

Question: HI. I haul gas for a Major trucking company in michigan we have several 6axle trailers with compartment sizes 4000/2000/1400/2000/4000 and 4700/1150/1750/2900/2900. And it seems when I ask what the lift axle pressure should be set at everyone would give me an unsure answer like their guessing. Can you provide the correct psi for the front / rear lifts and also when we do split loads does the front lift axle have to be used if say, comp 1 2 3 are only used? Thank you. Ryan

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.

Question: Dear Sirs, I am working on a project with an engineering company that is building a gasoline truck loading terminal in Trinidad. The engineer says the truck are 9,000 gallon capacity and are British Heil Trucks. Do you know what type of coupler I need to connect my companies loading arms to this type of truck? Chris

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.

Question: Hello - We have a number of your 1650 cu/ft flour trailers. Do you have a recommended wash procedure that you can provide. We are having problems with product getting in the aerators and turning to dough. Thanks - Rick

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.

Question: Our company has a Heil crude oil tanker hauling only "sweet" product, but we are entering a new service area. Should we be concerned about corrosion caused by hauling crude oil with a small amount of H2S (under 150 ppm) in an unlined tank? Eric

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.

Question: Hi John, I am writing about cracks on box mounts and fender mounts. My 1990 tanker unit and others in the fleet haul h2o2, which all have cracks. Is there an update on the mounts (i.e. bolt on and not weld or rubber gaskets)? thanks for your time.... Glenn

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.

Question: Many companies these days are more concerned about quantity over quality. How do the manufacturers rank in quality and workmanship among each other? Also, who is the best custom tank manufacturer?

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 be
