Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on Article 11 of this article, which relates to both values of vehicles such as dump trucks.
The present invention relates to a device for mechanically and automatically transferring and removing a coating rate of 1 Kjlt.

In order to protect the interior of the vehicle's grape box from wind, rain, snow, and foreign objects, or to prevent scattering of product 1rIO from scattering to the outside world, the campus sheet is tied up with a rope and placed on the cargo box.
The work of hanging an rc canopy.

It requires a lot of effort and time, and is dangerous. The hood can be quickly and mechanically removed, and it can be done automatically by touching the driver's seat from the driver's seat. This will save labor and improve the quality of vehicle yoke, however. Conventional devices of this kind do not have fully satisfactory functions in terms of coverability and operability, and the device provided a solution to this problem when it came to covering the cargo box of the 90 unexploded W14. Therefore, while reducing the roundness of the vehicle (O1) by adjusting the linkage and the rotation control arm, by elongating the seat, the wide hll of the earthen floor of the cargo box is reduced. It has the advantage of being able to operate the target KI automatically and requiring relatively low torque for operation.
