Description

The engineering gantry crane is mainly composed of a bridge, a traveling mechanism, a lifting mechanism, an electrical system and other parts. The engineering gantry crane controls the movement of the lifting mechanism and the traveling mechanism through the electrical system to achieve the lifting, handling and positioning of heavy objects. The lifting mechanism rolls up or lowers the wire rope through the hoisting device to lift or lower the heavy object. The traveling mechanism moves the gantry crane on the construction site through the rotation of the driving wheel.
