Forklift tip-over attachment

The invention relates to a forklift tip-over attachment which is composed of a base, a tip-over frame, a jacking oil cylinder, a left overturning oil cylinder, a right overturning oil cylinder, a left goods blocking arm rod, a right goods blocking arm rod and a goods blocking frame. The base is used for being detachably arranged on a fork of a forklift. The base and the front end of the tip-over frame are rotationally hinged to each other. The fixed end of the jacking oil cylinder is arranged at the rear end of the base. The piston rod ends of the oil cylinders are used for vertically jacking the tip-over frame but not being connected with the tip-over frame. One ends of the overturning oil cylinders are hinged to the middle of the tip-over frame, and the other ends of the overturning oil cylinders are hinged to the rear end of the base. The goods blocking frame is located at the front end of the vertical segment of the tip-over frame and can move forwards and backwards relative to the vertical segment. The goods blocking arm rod is in an L shape and arranged on the tip-over frame. A bent segment of the front end of the goods blocking arm rod can horizontally rotate and is vertically upward. By means of the forklift tip-over attachment, boxes on the attachment are tipped over forwards to dump goods while it is guaranteed that the boxes cannot fall off, mechanical and professional operation is achieved, working efficiency is improved, and the labor cost is lowered.
