Some little knowledge about industrial drivable gantry crane

industrial drivable gantry crane is a variant of bridge crane

It is mainly used for loading and unloading operations in outdoor cargo yards, material factories, and bulk cargoes. Gantry cranes have the characteristics of high site utilization, large operating range, wide application, and strong versatility, and are widely used in port cargo yards.

Its metal structure is like a door-shaped frame, with two legs installed under the main beam, which can walk directly on the track on the ground. Both ends of the main beam can have outstretched cantilever beams.

A sevencrane drivable 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. Some gantry cranes only have outriggers on one side, and the other side is supported on a factory building or trestle, which is called a semi-gantry crane. The gantry crane is composed of the upper bridge frame (including main beam and end beam), outriggers, lower beam and other parts. In order to expand the crane’s operating range, the main beam can extend beyond the outriggers to one or both sides to form a cantilever. A lifting trolley with a boom can also be used to expand the crane’s operating range through the pitching and rotation of the boom.

Generally speaking, general-purpose custom drivable gantry crane suppliers are relatively common and highly practical. They consist of a gantry, a trolley operating mechanism, a lifting trolley and electrical parts. The semi-gantry crane has only one side supported on the ground. The structure of the gantry includes the upper bridge, outriggers, lower beams and other parts. Nowadays, the operating range of cranes has been expanded to a large range. The main beam can be modified into a cantilever, or a lifting trolley can be used to promote and apply the gantry crane’s operating range to a certain extent.

According to different structural characteristics, drivable gantry crane manufacturers can be divided into hook gantry cranes, grab gantry cranes, electromagnetic gantry cranes, and dual- or three-purpose gantry cranes. Among them, the hook gantry crane is suitable for larger places, such as stations, docks, large enterprise factories, freight yards and warehouses; the grab gantry crane is suitable for some scattered and large-scale transportation; dual-purpose or Three-purpose gantry crane is used in places where materials change frequently.
