Abstract

The invention discloses a crane hook with an anti-falling device. The crane hook comprises a hook handle, wherein the bottom part of the hook handle is fixedly connected with a hook body; the hook handle is movably connected with an anti-falling rod through a rotary shaft; the anti-falling rod comprises a casing; a bolt hole is formed in the bottom part of the left side of the casing; a telescopic rod is penetrated into an inner cavity of the casing; the bottom part of the telescopic rod penetrates through the bottom part of the casing, and extends to the exterior of the casing. The crane hook with the anti-falling device has the advantages that the telescopic anti-falling rod is used on the hook, so that when a coarser steel wire rope needs to be placed, the telescopic rod is put into the inner cavity of the outer casing, then the outer casing is pressed down, a gap is increased, and the coarser steel wire rope is conveniently placed; by arranging a reset device on the hook, when the anti-falling rod is pressed down, the anti-falling rod can rebound via the reset device; the practical effect is obvious, the structure is simple, the operation is convenient, and the crane hook is suitable for being popularized.
