Claims

[Scope of Claim for Utility Model Registration] 1. A dump truck in which the front part of the loading platform can be raised as necessary by actuating means using a cylinder to discharge loads such as earth and sand, and a driver's cab is provided at the front end of the loading platform. At the same time, a link mechanism is attached to the cargo platform, one end of which is hinged to the protector so that the protector can be tilted toward the cargo platform or raised toward the driver's cab, and the other end of the link mechanism is attached to the cargo platform. A dump truck loading platform characterized by a hinge connected to the rod end of a cylinder attached to the loading platform. 2. In a dump truck whose front part of the loading platform can be raised as necessary by actuating means using a cylinder to discharge cargo such as earth and sand, a protector that covers the rear of the driver's cab is pivotally attached to the front end of the loading platform. At the same time, a link mechanism is attached to the side of the cargo platform so that the protector can be folded down to the cargo platform side or raised to the driver's cab side, one end of the link mechanism is hingedly connected to the lower part of the protector, and the link mechanism is The other end is fixed to a rotating shaft pivotally supported at the lower part of the front end of the loading platform, an engaging member is further fixed to the rotating shaft, and a locking portion with which the tip of the engaging member removably engages is attached to the front end of the loading platform. The protector is provided on the upper part of the vehicle body located below, and when the loading platform is raised or lowered by the actuating means, the tip of the engaging member is attached to and detached from the locking portion, and the protector falls down to the loading platform or to the driver's cab side via the link mechanism. A dump truck loading platform that is characterized by its appearance.
