What principles should be followed in the design of mining material trucks?

The underframe of the mining material car shall be completely consistent with that of the corresponding mining car. Except for the car body, other dimensions shall be the same as that of the mining car as far as possible.

Outline dimension of the car body: The car height can be the same as that of the tramcar, because the roadway section will be higher if it is too high. The car width is also related to the roadway, so you must pay attention not to go in and out too much with the tramcar. In addition, when considering its length, the following conditions must be met:

1. Must be able to pass through the tunnel with the minimum radius underground;

2. A certain distance shall be kept between the rain end of the material truck and the cage frame in the cage, otherwise the material may stretch out of the cage.

3. The traction force of the coupler of the material car shall be considered according to the traction force of the electric locomotive, which shall be consistent with that of the tramcar.
