<p><P>PROBLEM TO BE SOLVED: To provide a crane which prevents the torsion of a bar pendant caused by the twisting back of a rope pendant. <P>SOLUTION: The crane has pendants 24A and 24B that connect the tip portion of a boom with the tip of a live mast. The pendants 24A and 24B have a rope pendant 241 and a bar pendant 242 that are connected at the same position in the extending direction of each of the pendants, a shaft 250 connecting a connecting member (link mechanism 26) between the rope pendant 241 and the bar pendant 242 of the pendant 24A, and a connecting member (link mechanism 26) between the rope pendant 241 and the bar pendant 242 of the pendant 24B, and a connecting pin 251. Thereby, even if torsion torque is generated in each rope pendant 241 due to tension, the shaft 250 prevents the rotation of the connecting member, i.e., the bar pendant 242, and the torsion of the bar pendant 242. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
