Integrally turning method of tower crane

The invention discloses a large-scale tower crane whole turning method. It includes steps that the first is arranging the template beam and no less than one jack under the gantry mounting secondary beam; the second is removing the connection of the two sets of loop wheel machines and end frame; the third is jack up the gantry mounting by the jack; the forth is pushing a set of loop wheel machine along the railway, and the railway is turned ninety degree, and the loop wheel machine is pushed to the under of the gantry mounting end frame; the fifth is repeating the forth, and completing the turning of the other loop wheel machine; the sixth is put down the gantry mounting, connecting the loop wheel machines and bolt of the end frame; the seventh is turning the machine table for one hundred and eighty degree, installing the connecting arm tie of the machine table and the gantry mounting, and the template beam and jack are removed to the other side; the eighth is repeating from the first to the sixth, completing the other side turning of the loop wheel machine and railway under the gantry mounting. Before the first step, tower crane arm rod is vertically stopped on the railway, and the connecting arm tie of the machine table and the gantry mounting is installed and fixed. The advantages of the invention are that it can quickly remove the tower crane to the purpose position; the efficiency is high; the safety is high; and the cost is low.
