REPLACEMENT MECHANISM OF CLIMBING CRANE AND FLOOR CLIMBING CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a replacement mechanism of a climbing crane and a floor climbing construction method realizing high efficiency of field work and large reduction in a steel material quantity such as post members used in replacement.;SOLUTION: The post members (a base stand support member) 6 are arranged on a replacing floor, and in the post member, a climbing reaction structure base 1 formed by arranging the lower end of a portal frame body 1b narrower in a width than a receiving beam, is arranged on an upper surface of the receiving beam 1a arranged in parallel. The portal frame body does not cause interference with a mast 3, and is formed in a height for receiving a base stand 2. The receiving beam is detachably arranged on the post member so that a load of a lifting device 4 placed in the portal frame body is transmitted to the post member via the climbing reaction structure base. The base stand 2 is pushed up to the replacing floor by the lifting device placed in the portal frame body, and is arranged on the post member.;COPYRIGHT: (C)2011,JPO&INPIT
