Gate crane (also known as gantry crane) is a bridge crane whose bridge is supported on ground rails by legs on both sides. Structurally, it consists of a gate frame, large crane running mechanism, lifting trolley, and electrical parts. Some gate cranes have legs only on one side, while the other side runs on a building or trestle, called semi-gantry crane. The gate frame of a gate crane is composed of the upper bridge (including main beam and end beams), legs, lower crossbeam, etc. To expand the working range of the crane, the main beam can extend beyond the legs to one or both sides, forming a cantilever. It can also use a lifting trolley with a jib, expanding the working range through the pitching and rotation of the jib.

Gate crane is a deformation of bridge crane, also called gantry crane. It is mainly used for loading and unloading operations of cargo yards, material yards, and bulk materials outdoors. Gate cranes have the characteristics of high yard utilization rate, large working range, wide adaptability, and strong versatility, and are widely used in port cargo yards. Its metal structure resembles a door-shaped frame, with two legs installed under the load-bearing main beam, which can walk directly on ground rails, and the ends of the main beam may have outward extending cantilever beams.
