Abstract

The invention discloses a double-girder multi-lifting-point crane and a working method thereof, and relates to the technical field of cranes. The double-girder multi-lifting-point crane comprises two groups of gantries, double girders are fixedly connected between the two groups of gantries, an electric hoist is mounted in the double girders, a hook is mounted at the bottom end of the electric hoist through a connecting block, a multi-hanging-point hanger is installed at the outer side of the hook and comprises an assembly box, a plurality of winders are installed in the assembly box, a plurality of locking components used for limiting the winders are installed on the side face of the assembly box, and a reinforcing device is installed at the upper side of the assembly box. By means of the double-girder multi-lifting-point crane, the number of connecting points of the crane and a to-be-lifted object can be increased, the stability during lifting of a large object is improved, and the multi-lifting-point hanger is composed of two sets of box bodies, so that a user can conveniently assemble the multi-lifting-point hanger and the connecting block; and meanwhile, the multi-lifting-point hanger is provided with a reinforcing device, so that the overall stability of the multi-lifting-point hanger can be enhanced.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a crane with double main girders and multiple lifting points and a working method thereof. Background technique [0002] A crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range. When the existing cranes are working, most of the objects are lifted by hooks and moved on the main beam by electric hoists. [0003] After retrieval, a Chinese patent discloses a multi-lift crane (publication number: CN101607676B). The patent includes a main beam, an operating mechanism, a lifting mechanism, and an electric control system. The operating mechanism includes a bearing mechanism composed of a roller device and an elastic body. And the driving mechanism composed of motor, reducer, drum set, two sets of wire ropes, pulley block and pulley bracket; It adopts the form of multi-layer winding and symmetrical lowering,...
