1、车厢长度.2、整车长度。3、如果是自卸车，还要特别注意一下后悬长度。

1. The length of the car is.2 and the length of the whole car. 3, if it is dump truck, pay special attention to the rear suspension length.

以上三个长度，要根据你的工况、运输条件等来确定。

The above three lengths should be determined according to your working conditions and transportation conditions.

举例：1、用户需要的载货量，来确定车厢长度。因为这牵扯到运价的问题。2、如果工地较小，不要选太长的车，不然转弯都不行。3、后悬不要太长，不然容易把车头撅起来，尤其是上坡时坡度太大的话。

For example: 1, the volume of freight required by the user to determine the length of the carriage. Because it is involved in the problem of freight rates. 2, if the construction site is small, do not choose too long a car, otherwise it will not be able to turn. 3, the rear suspension should not be too long, otherwise it would be easy to pat up the front part of the car, especially when the uphill slope is too large.
