The invention discloses a crane grounding protection device used for solving the problems of personnel casualty and equipment damage due to crane electric shock. The device comprises a grounding pile, a conducting wire, and a grounding clamp, the grounding pile is a rod-shaped metal conductor, one end of the grounding pile is sharp, the other end of the grounding pile is connected with the grounding clamp via the conducting wire, the length of the grounding pile is at least 600 mm, the grounding clamp is used for being connected with a crane and made of a metal conductor, and a handle of the grounding clamp is wrapped by an insulation sheath. According to the crane grounding protection device, when a power failure line electrostatic interaction occurs and more than 0.4 kV voltage is touched by a large arm of the crane, the current flows to the ground via a crane grounding wire, drivers of the crane are prevented from electric shock, labor saving and time saving are realized, the problem that the life safety of the crane drivers is threatened by the live large arm of the crane in a long term is solved, and casualty accidents due to power failure line static charge electric shock are prevented.
