The system further includes apparatus to lock and unlock the locking pins that lock the trailer axle group(s) in position on the rails.
Tractor trailer axle weight distribution driver#
The information is presented to the driver on a display located in the cab of the truck. The microprocessor(s) is programmed to calculate the weight on each axle group and determine any change in position of the trailer axle group(s) on the rails to optimize the weight distribution. The position of the trailer axle groups relative to the rails is also determined and the position delivered to the microprocessor(s). The measurements are delivered as an electrical signal to one or more microprocessors capable of receiving the electrical signals and calculating the optimum position of the axle group on the trailer. or indirectly, by taking measurements from the air suspension system to calculate weight. The measurement may be of weight directly by load cells etc. The system for adjusting weight distribution according to the present invention measures the weight on every axle group on the truck and trailer. These axle groups are locked in position on the rails by locking pins. The trailer has at least one axle group mounted on a pair of rails attached to the frame of the trailer. Gross Weight: 80,000 lbs.The present invention relates to a system for adjusting weight distribution throughout all axle groups of the truck and trailer.
State-by-State Commercial Truck Axle Weight Limits Note that cargo and tractor and trailer cannot exceed 80,000 gross weight. The US Department of Transportation compiles this information so that owner/operators can be aware of the limitations they should be aware of as they make trips cross country. Adherence to these standards will make driving safer for everyone on the road and will ensure that the roads themselves are not damaged by the weight of the vehicles. In addition, some bridges and overpasses might not be able to support heavier weights, so there is a genuine safety issue associated with carrying too much weight.įor this reason, each state has established standards for the maximum amount of weight that any commercial truck is allowed to carry on a single axle, a double axle, and a tridem axle. If a truck is carrying too much weight, it could well pose problems for roads which are not designed to support that much weight, and damage could occur. The reason that axle legal weights are significant for commercial trucks is that both state and federal authorities are concerned about the safety of truckers, other motorists, and the roads they drive on as well.
