゛[Claims for Utility Model Registration] 1. A slide frame that surrounds the mast is attached to the mast so that it can be raised and lowered freely by a lifting device, and a revolving body that can pivot around the mast via a swing ring is attached to the slide frame. ,
A boom is attached to the revolving body, and the lifting device hooks and rotates the lifting rope, which is wound and unwound to the lifting winch provided on the slide frame, to sheave beaters installed on the frame attached to the mast and the slide frame, respectively. In the crane, the sliding frame is provided with a safety rope drum that is rotated forward and backward by a constant rotation, and the safety rope that is wound up and fed out by the drum is attached to the frame attached to the mast and the sliding frame, respectively. The safety rope drum is equipped with a negative brake, and the negative brake is activated when the tension detector detecting the tension of the lifting lobe detects a tension below a predetermined value. - A lifting device for a crane, characterized in that it has a safety device configured to operate so that the slide frame, revolving body and boom are supported by a mast via a safety rope. 2. The mast and slide frame have a rectangular shape, and the frame to which the sheave for hanging the safety rope and lifting rope is attached is a square frame, and the lifting winch and the safety [
The 1-build drums are attached to two adjacent sides of the four sides of the slide frame, and the lifting robes and safety ropes are hung on the square frame and the slide frame on the same side and on the opposite side of each winch. Attach the sheave and connect the lifting rope to 2.
Hang one of them as a book on the jeep on the same side as the lifting winch on the rectangular frame and slide frame, and hang the other one on the sorb on the opposite side of the lifting winch through the guide sheave attached to the slide frame. The safety rope is hung on a sheave on the same side as the safety rope drum on the rectangular frame and the slide frame, and is also hung on a sheave on the opposite side via a guide sheave on the slide frame. A lifting device for a crane as set forth in claim 1 of the utility model registration claim.
