摘要： PURPOSE: To prevent the derailment of a traveling wheel and the damage of a traveling leg part when the land slide is generated in a wharf due to the earthquake and the traveling track is displaced in the lateral direction. CONSTITUTION: A hydraulic mechanism 27 is kept at the prescribed length during the normal crane operation, and serves as an impact buffer equipment against the impact during the operation. When the land slide is generated in the wharf 1 due to the earthquake, etc., and the traveling track 2 on the sea side is displaced to the position 2', the high horizontal load is applied to the traveling wheel 2 on the sea side, a pressure relief valve is operated, the pressurized oil flows from the pressed rod side to the head side, the hydraulic mechanism 27 is operated in the expanding direction, and a U-shaped leg on the sea side is turned from the solid line position to the dotted line position around the horizontal shaft 24 to prevent the derailment of a traveling wheel 3 on the sea side or the damage of a traveling leg part 10. When the traveling track 2 on the sea side is displaced in the opposite direction to that mentioned above, the hydraulic mechanism 27 is operated in the contracting direction to prevent the derailment of the traveling wheel 3 or the damage of the traveling leg part 10.
