Single Girder 20 Ton Gantry Crane With Weight Overload Protection Device
Introduction:
The upper bridge frame of the gantry crane (including the main beam and the end beam), the outriggers, the lower beam and other parts are composed. In order to expand the working range of the crane, the main beam can extend beyond the outriggers to one or both sides to form a cantilever. A hoisting trolley with a jib can also be used to expand the crane's operating range through the pitch and rotation of the jib.
It is mainly used for the loading and unloading of outdoor cargo yards, stockyards and bulk cargoes. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability and strong versatility, and are widely used in port cargo yards.
