Description

A gantry crane with windproof function for bridge construction

technical field

The utility model relates to the technical field of building construction, in particular to a gantry crane with windproof function for bridge construction.

Background technique

The gantry crane is a bridge type crane in which the bridge is supported on the ground track by the outriggers on both sides. Structurally, it consists of a gantry, a cart running mechanism, a hoisting trolley and electrical parts. Some gantry cranes only have outriggers on one side, and the other side is supported on the workshop or trestle, which is called a semi-gantry crane. The upper bridge frame of the gantry crane (including the main beam and the end beam), the outriggers, the lower beam and other parts are composed. In order to expand the working range of the crane, the main beam can extend beyond the outriggers to one or both sides to form a cantilever. A hoisting trolley with a jib can also be used to expand the working range of the crane through the pitch and rotation of the jib. The gantry crane plays a great role in the outdoors, and the wind is the most obvious damage outdoors.
