Abstract

The invention provides a construction method and device for installing and disassembling a gantry crane in radial type. The device comprises a rail, a gantry crane landing leg, a girder, a patand, and an assistant device mounted on the gantry crane body. While the device is used for constructing, the method comprises three steps of making the assistant device, installing the gantry crane and disassembling the gantry crane. The method and device can install and disassemble the gantry crane more conveniently, save the installing and disassembling cost, and improve the installing and disassembling safety of the gantry crane.

Description

technical field [0001] The invention relates to a construction method for installing and dismantling a gantry crane, in particular to a set of construction methods and devices for installing and dismantling a gantry crane using hinged joints. Background technique [0002] In the process of large-scale building construction, especially in the construction process of large-scale industrial buildings, the gantry cranes that need to be temporarily processed and used in the production site are often dismantled, transferred, and installed according to the needs of use. Removal and installation of traditional gantry cranes. Firstly, the outriggers of the gantry crane are temporarily fixed, and then the main girder of the gantry crane is hoisted in place by a truck crane. At present, when using this method to install and dismantle the gantry crane, the outriggers often collapse due to insufficient reinforcement of the outriggers or collision with the main girder during hoisting. Th...
