Abstract
PURPOSE: To provide an automatic opening/closing apparatus which enables the binding of the gate of a dump truck regardless of the tilting of the dump body for example at the draining of the load without any manual opening/closing device by making the angle for releasing larger than that of binding the gate entailing the tilting of the body.
CONSTITUTION: When a dump body 1 staying horizontal begins to be tilted on a hinge 4, a lever 14 supported rotatively with a support shaft 15 on a main fram 8 of the body 1 rises. A roller 16 supported on the tip of the lever 14 moves up along a guide way behind a toggle turing means 23. Consequently, as the angle of tilting dump body approaches the angle for releasing the gate (about 20°), upon contact with a projection 23C, the roller 16 turns the lever 14 and then, when it reaches the angle, a connecting shaft 18 for the lever 14 and transmission rod 17 moves upward beyond the dead point. The transmission rod 17 is moved backward by a spring 22 to open a hook 11 so as to be separated from a pin 10. In this manner, a rear gate is opened.
