20 ton gantry crane Description
Gantry crane (also known as gantry crane) is a bridge crane supported on the ground track by two side legs. In structure, it is composed of portal frame, cart running mechanism, lifting trolley and electric part. Some gantry cranes only have outriggers on one side, while the other side supports on the workshop or trestle, which is called semi-gantry crane. The upper part of the gantry frame of a gantry crane (including the main girder and end girder), the supporting legs, the lower cross beam, etc., is composed of the upper part of the gantry frame of the gantry crane. In order to expand the scope of crane operation, the main girder can extend beyond the outriggers to one or both sides to form a cantilever. Lifting trolley with boom can also be used to expand the scope of crane operation by pitching and rotating the boom.
