Background

Gantry cranes, also known as gantry cranes, are gantry cranes in which a gantry is supported on a ground rail by legs at both sides. Structurally, the crane consists of a portal frame, a cart running mechanism, a hoisting trolley, an electric part and the like. Some gantry cranes have legs on one side only, and the other side is supported on a factory or a trestle to run, and are called semi-gantry cranes. The gantry crane comprises a gantry upper bridge (comprising a main beam and an end beam), supporting legs, a lower cross beam and the like. In order to enlarge the operation 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 can also adopt a crane trolley with an arm support, the operation range of the crane is expanded through the pitching and the rotating of the arm support, and the crane is mainly used for the loading and unloading operation of outdoor goods yard, stock yard goods and bulk goods. The portal crane has the characteristics of high site utilization rate, large operation range, wide application range, strong universality and the like, and is widely used in port goods yards. The metal structure of the gantry crane is like a portal frame, two support legs are arranged under a bearing main beam and can directly walk on a track on the ground, cantilever beams extending out can be arranged at two ends of the main beam, and through years of development, the functions of moving on the ground and freely adjusting the height of a small gantry crane are realized.
