Claims

[Scope of utility model registration request]

A rear door is pivotally attached to the tip, a wire mounting plate is rotatably attached to the other end of the support arm which is rotatably pivoted to the upper edge of the dump bed, a wire is attached, and the wire is inserted into the wire guide ring. At the same time, the hook is passed from the rear lower part of the loading platform frame to the first double pulley and the second double pulley provided on the vertical center line of the loading platform chassis, and from the second double pulley,
On the longitudinal center line of the vehicle body chassis, the hook is passed to a single pulley having a wire guide and detachably provided to the vehicle body chassis, and the wire is placed at an appropriate position between the cargo platform frame and the first double pulley. A rear door opening/closing system for a dump truck loading platform that engages with a wire slack adjustment spring and is further equipped with a strong spring to prevent wire breakage at an appropriate position on the installed wire, allowing the rear door to open and close in conjunction with the vertical movement of the loading platform.
