The invention relates to the technical field of gantry crane collision prevention, in particular to an anti-collision device for gantry cranes. The anti-collision device overcomes the shortcoming thataccidents such as high-altitude fall and equipment in the gantry cranes derails are caused due to the fact that existing gantry crane rail terminals are prone to colliding. The anti-collision deviceincludes a vertical frame, a horizontally arranged cross beam is fixed to the top of the vertical frame through bolts, a guide rail is welded to the bottom of the cross beam, mounting plates are erected on the outer parts of both sides of the guide rail, electric hoist machines are fixed to the bottoms of the mounting plates through bolts, horizontally arranged sleeves are further welded to both sides of the mounting plates, buffer springs are arranged in the sleeves, ejecting plates are further arranged in the sleeves, reinforcing plates are separately welded to both sides of the end parts ofthe guide rail, and buffer pads are further glued on the inner sides of the end parts of the guide rail. When the electric hoist machines slide to the end parts of the guide rail, positioning plugs can be inserted into the sleeves, and the buffer springs can be compressed to achieve the effects of deceleration and braking, so that the gantry cranes are effectively prevented from colliding and derailing.
