Determining the load capacity of heavy-duty semi-tractor is based on two key factors: the number of axles and the weight of the vehicle. In general, the standard load capacity of a vehicle with two rear axles is set at 18 tons, while a vehicle with three rear axles can carry 24 tons.
In addition, according to the number of axes of the tractor, the placement position of the traction pin also needs to be adjusted appropriately. According to the relevant legal provisions, the maximum weight of a six-axle vehicle (including the body and the cargo carried) is 55 tons. When conducting a traction operation, we usually set the total traction mass to 40 tons, and by subtracting the trailer’s own weight from this value, we can determine the actual load.
Taking the trailer as an example, if its weight is 8 tons, then the total weight of the goods it can carry is 32 tons. Semi-trailer, as a key cargo handling tool, the axle is located at the rear of the body center of gravity and connected to the traction front by traction pins.
Semi-trailer has a variety of design styles, including 11 meters long bin type, 13 meters long bin type and low flat plate, etc. It is worth noting that the above information is only for the reference of the reader, and for the specific load capacity, it is also necessary to carry out in-depth calculations according to the specific situation of the vehicle.
