The difference between a square Truck and a U-Shape dump truck

The baffle at the rear of the square 6x4 plus three-axle semi-trailer dump truck is not vertical but has a certain slope, which is conducive to the unloading of sand and soil. The loading capacity of a square dump truck is generally larger than that of a U-shaped dump truck, but it is not as convenient as a U-shaped dump truck when unloading.

The U-shaped dump truck is also a 6x4 plus three-axle semi-trailer. The loading capacity of this dump truck is slightly smaller than that of the square dump truck, but it can ensure that the compartment is cleaner when unloading. However, if the load is clay, the dump truck with the square car and the U-car has no advantage in unloading.
