General-purpose gantry crane is a type of bridge crane, also called gantry crane, which is mainly used for outdoor cargo yard, stock yard, and bulk cargo loading and unloading operations. Its metal structure is like a door-shaped frame. Two supporting feet are installed under the main beam, which can walk directly on the ground track. The two ends of the main beam are designed with outhanging cantilever beams. Gantry cranes are widely used in port cargo yards due to their high site utilization, large operating range, wide adaptability and strong versatility.


   The general-purpose gantry crane has a span of 14.5m, a lifting height of 6m, and a lifting MG50/16T. It adopts a box-shaped double-beam welded structure. There is also a truss type (flower type) with a model M. MG means double-beam portal type, generally equipped with main and auxiliary hooks, such as 50/10T, 32/5T, etc. The box-shaped double-beam welding structure not only increases the working space, but also facilitates the transportation, installation and maintenance of the crane. The end beam is a torsion resistant welded box beam structure. In the later process of the main end beam connection, the process of laser calibration and countersinking of the connecting plate and the connection with 10.9 high-strength bolts are used to effectively ensure the rigidity and accuracy of the equipment. The trolley is conductive with flexible cables, and the trolley is with sliding contact line type and cable reel type for selection. It adopts a closed air-conditioning control room and is equipped with a linkage console control. It has a wide field of view, flexible operation, comfortable work, and high work efficiency. advantage.
