We purchased a 51' 4-axle Heil Trailer pull trailer from Semi Service in June of 2013. We have been very pleased with our increased payload, the durability of the trailer and the outstanding business relationship we have built with the team at Heil Trailer and Jim Amicone at Semi Service. With the success we have had with this product, I look forward to doing business again with Heil Trailer and Semi Service.Jon Shepherd, Services President, Northwest Petroleum
Question: Hi, I haul gas for a major trucking company in Michigan. We have several 6-axle trailers with compartment sizes 4000/2000/1400/2000/4000 and 4700/1150/1750/2900/2900. It seems when I ask what the lift axle pressure should be set at; everyone gives me an unsure answer, like they’re guessing. Can you provide the correct psi for the front / rear lifts. 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

Answer: 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.
