Claims

[Scope of Claim for Utility Model Registration] (1) A suspended body that is suspended from a suspended part of a crane, and a fluid pressure supply source that is connected to this suspended body by a high-pressure hose, and the suspended body is It is equipped with a pair of support members that can slide vertically relative to each other and a fluid piston device that connects these support members, one of the support members is provided with a connection means that connects to the suspension part of the crane, and the other is provided with a connection means that connects the suspension part of the crane. is provided with a hanging means for holding a suspended object, and the fluid piston device has its main body fixed to one of the supporting members, and the piston rod is fixed to the other supporting member in such a manner that the piston rod protrudes and retracts in the vertical direction. A lifting height adjusting device for a crane, which is fixed to a member and configured to drive the fluid piston device by operating the fluid supply source, thereby raising and lowering the suspended object using the connecting means as a fulcrum. . (2) The support member is an outer cylinder and an inner cylinder that are fitted into each other, and the fluid piston device is housed in the inner cylinder, and its piston rod is fixed to the inner surface of the inner cylinder, and the main body of the device is connected to the cylinder. A lifting height adjusting device for a crane according to claim 1, which is connected to an end of an outer cylinder through a slit, and has a cut window formed in the inner cylinder to enable vertical movement of the connecting rod. .
