Abstract

The present invention pertains to a device for automatically opening and closing a cargo box cover of a dump truck, which is provided on a cargo box of a dump truck to prevent cargo from falling out. More specifically, a winding type rolling device is mounted to the cargo box and guide rails are provided at both sides of the cargo box so that rolling plates may be withdrawn from or wound on the winding type rolling device. Accordingly, the rolling plates are withdrawn along the guide rails so as to enable the cargo box to be covered with ease. Therefore, loaded cargo is completely prevented from falling out or being exposed to the outside.
