1. Closed performance: Dump trucks have good sealing performance to ensure no dust or leakage during transportation. This is the basic requirement for installing the roof system.

Second, safety performance. Dump-type garbage truck has good safety performance, and the closed box cover cannot exceed the body of the vehicle, affecting normal driving and creating potential safety hazards. Changes to the vehicle should be reduced to ensure that the center of gravity when the vehicle is loaded does not change.

Use the performance surface. The dump truck is easy to use and the roof system can be opened and stowed in a short period of time. The cargo will not be affected during loading and unloading.

4. Appearance: Dump trucks are small in size and light in weight. Try not to take up the internal space of the car body, and the self-weight should not be too big, otherwise it will cause the transport efficiency to drop or overload.

V. Persistence: Dump trucks have good reliability. The life of the entire closed box cover system will be much longer than other cars, and the maintenance cost will be much less.
