The portal crane has the characteristics of high field utilization rate, large operation range, wide application range, strong universality and the like, and is widely used in port cargo yards. Gantry cranes (also known as gantry cranes) are bridge type cranes in which a bridge is supported on a ground track by two side legs. Structurally consists of a portal frame, a cart running mechanism, a trolley, an electric part and the like. Some portal cranes have legs on one side only and the other side is supported for operation on a building or trestle, known as semi-portal cranes. The portal upper bridge frame (comprising a main beam and an end beam), supporting legs, a lower cross beam and the like of the portal crane. In order to expand the working range of the crane, the main beam can extend out of the supporting legs to one side or two sides to form a cantilever. The crane trolley with the arm support can be adopted, and the operation range of the crane is enlarged through pitching and rotation of the arm support.
