Question: I am transferring plastic pellets from a rail car to a Heil Trailer dry bulker. When I transfer from the rail car, do I need to leave the bulker trailer brakes off? Do the brakes have any effect on the blowing of the load?
Answer: 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.
Question: Is there a MC/DOT specification cargo tank listed in 49 CFR 173.242 which is practical for hauling bulk hazardous (dry granular) products that are unloaded by pressure (up to 15 psi)? Mike
Answer: Sorry, Mike, we are unaware of any such permit. You should contact the DOT and see if they can be of more assistance.
