The invention discloses a disassembling and installing method of a TC6015 tower crane. A construction elevator is adopted for vertical transportation of a 3-ton roof crane, and manual installation iscarried out by manually horizontally carrying the 3-ton roof crane to reach the intended position; a 6-ton roof crane is installed on the 3-ton roof crane, a 25-ton roof crane is installed by adoptingthe 6-ton roof crane, and a TCR 6030 tower crane is installed on the 25-ton roof crane; after the TCR 6030 tower crane is jacked up, the TCR 6030 tower crane is jointly matched with the 25-ton roof crane to jointly detach a TC6015 tower crane which is deformed on site; the TC6015 tower crane is reconfigured to independently complete installation activities by adopting the TCR 6030 tower crane; and after the TC6015 tower crane is installed, all auxiliary disassembly and installation equipment is disassembled. According to the technical scheme, the task of disassembling and installing the TC6015 tower crane can be completed on the premise of ensuring safety.

Disassembling and installing method of TC6015 tower crane

The invention relates to a novel cargo boom mounting mode of a boom tower crane and belongs to the technical field of boom tower cranes. After the boom tower crane completes mounting of a rotating platform, a counterweight, a tower top and an amplitude-change mechanism, the cargo boom mounting is carried out, and the cargo boom mounting steps are as follows: winding of an amplitude-change steel wire rope is carried out; a cargo boom and a lifting steel wire rope are mounted; and a cargo boom pull rod pulley block is mounted. The novel cargo boom mounting mode has the beneficial effects that the safety is high, the lifting steel wire rope is wound around the boom, the boom end is fixed by the rope end, the operations are completely completed on the ground, and the high-risk work such as thesituations that an auxiliary crane is adopted for dragging and mounting personnel need to walk back and forth at the high attitude is avoided; the mounting efficiency is high, the lifting steel wirerope winding process is completely completed on the ground, compared with the high-altitude work, by the adoption of the novel cargo boom mounting mode, the time is greatly saved, an auxiliary mechanism is utilized to mount the crane boom pull rod pulley block, the mounting is fast, and the cost is saved; and the humanization design is high, the work high above the ground is reduced greatly, the working time of the work high above the ground is greatly shortened, and the humanization is high.
