The invention relates to a lifting hook buffering device. The lifting hook buffering device comprises a spring and a sliding block. The lifting hook buffering device is characterized in that a ring (2) is arranged at the upper end of a lifting hook (1); a hole (3) is formed in the upper part of the ring (2); the spring (4) is mounted in the hole (3); a rectangular space (5) is formed in the upper part in the ring (2); the sliding block (6) is mounted in the space; an arc-shaped groove (8) is formed in the lower end of the sliding block; clamping blocks (7) are mounted on two sides of the sliding block. According to the lifting hook buffering device, the deficiency that the bearing of the existing lifting hook suddenly changes in a lifting or detaching process because a steel wire rope and a lifting hook ring of the existing lifting hook are directly connected is overcome; the lifting hook buffering device has lots of advantages of simple structure and production process, low cost and remarkable buffer effect and is convenient to mount and use.
