Claims

[Claims for Utility Model Registration] 1. The inner cylinder is slidably fitted into the outer cylinder,
In a crane anti-tilt device that uses an elastic member between two outer cylinders to buffer and absorb external forces using the elastic force of the elastic member, a slight gap is created between the outer cylinder tip and the outer periphery of the inner cylinder. A crane tilting prevention device characterized in that a gap adjustment plate that is open and close to each other is fixed, and a gap adjustment plate that is slightly close to the inner periphery of an outer cylinder is fixed to the tip of an inner cylinder. 2. A groove-shaped notch is formed in one of the plate at the tip of the outer cylinder and the plate at the tip of the inner cylinder, and the other is formed in an outer shape that allows it to be inserted into the notch. A crane tilting prevention device according to claim 1 of the utility model registration claim.
