The gantry crane has a simple structure and is easy to operate, and its bridge is firmly supported on the ground by brackets on both sides. It is like a dragon entrenched on the clouds, so the gantry crane is also called a gantry crane.

A gantry crane is a bridge-type crane in which the bridge is supported on the ground track through outriggers on both sides. Structurally, it consists of a mast, a trolley operating mechanism, a lifting trolley and electrical parts.

Gantry crane 1. Full gantry crane: the main beam has no overhang, and the trolley moves within the main span. 2. Semi-gantry crane: The outriggers have height differences, which can be determined according to the civil engineering requirements of the site.

Railway gantry crane is a lifting equipment specially designed for use in the railway field. It is a very important railway mechanical equipment. Its main function is to carry out handling, loading, unloading and maintenance work on railway lines. The installation of rails, switches, sleepers, and other heavy components and equipment required for railway construction requires the assistance of a railway gantry crane.

Simple gantry crane is also called: light gantry crane, light gantry crane, small gantry crane, small gantry crane. It has a lifting capacity of up to 2,000 kg and is a movable light gantry crane. It can be easily used wherever it is impossible or uneconomical to use a suspended crane. Light gantry cranes can be simply disassembled into several easily transported parts and quickly assembled at another place of use, a feature that is beneficial in many situations. The lifting capacity of I-beam trackless gantry crane can reach 2000 kg.

(1) According to the main girder classification, general gantry cranes can be divided into single main girder gantry cranes and double main girder gantry cranes. (2) According to cantilever classification, general-purpose gantry cranes can be divided into single-cantilever gantry cranes, double-cantilever gantry cranes and non-cantilever gantry cranes.
