Claims

[Scope of Claim for Utility Model Registration] 1. In a crane that suspends and supports a predetermined hanging device by means of a hook housed in a guide frame placed below the main body of the moving crane, the connection between the main body of the crane and the guide frame 1. A steadying device for a crane hoist, characterized in that an upper shock absorbing mechanism having a spring is interposed between the hoist and the guide frame, and a lower shock absorbing mechanism having a spring is interposed between the hoist and the guide frame. 2. The upper buffer mechanism has a flexible shaft inserted through the support member attached to the lower surface of the crane main body and the upper member of the guide frame, and at least one end of the upper or lower end of the flexible shaft can move up and down with respect to the support member or the upper member. 2. The anti-sway device for a crane hoist according to claim 1, further comprising a spring which is freely slidable and is surrounded by a flexible shaft, and which is elastically compressed between the support member and the upper member. 3. The lower shock absorbing mechanism includes a flexible shaft whose lower end is engaged with a connecting member fixed to the upper part of the hanging device, which is movable up and down, and is fixed to an upper receiving plate attached to the upper end of the flexible shaft and the upper surface of the connecting member. 3. The anti-sway device for a crane hoist according to claim 1 or 2, further comprising a spring that surrounds the free shaft and is resiliently compressed between the lower support plate and the lower support plate. 4. The lower buffer mechanism has a storage cylinder fixed to the lower member of the guide frame, the lower end is pressed against the upper surface of the hanging tool, and the upper end is engaged with a flexible shaft that passes through the lower member and the storage cylinder so as to be vertically movable, 3. The anti-sway device for a crane hanging tool according to claim 1 or 2, wherein a spring that surrounds the flexible shaft is compressed in a resilient state between a lower receiving plate attached to the flexible shaft and an upper position of the storage cylinder. 5. The lower shock absorbing mechanism has a pressure stopping part on the lower member of the guide frame, the lower end of which is pressed against the upper surface of the hanging tool, and a flexible shaft with which the upper end is engaged is inserted through the lower member so as to be movable up and down, 3. The anti-sway device for a crane hoist according to claim 1, wherein a spring surrounding the shaft is elastically compressed between the stopper part and the lower member.
