Granite And Marble Stone Lifting Use Double Girder Gantry Cranes For Sale

General Introduction:

The gantry crane is a bridge-type crane in which the bridge is supported on the ground track by the outriggers on both sides. Structurally, it consists of a gantry, a cart running mechanism, a hoisting trolley and electrical parts. Some gantry cranes only have outriggers on one side, and the other side is supported on the workshop or trestle, which is called a semi-gantry crane. 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.

Under normal circumstances, the lifting capacity is less than 50t, the span is less than 35m, and there are no special requirements for use, the single main beam type should be selected. If the width of the gantry leg is required to be large, the working speed is high, or the heavy and long pieces are often lifted, the double-girder gantry crane should be selected.
