Product Description

Product Description

QZ Electric Grab Bridge Crane 

QZ electric grab bridge crane is mainly comprised of box- shaped bridge, grab crab, trolley travelling mechanism, cab and electric control system. The load handling device is the grab which is able 1 to capture bulk materials.
The grab crab has switching mechanism and lifting mecha anism. The grabs are separately hung over the switching mechanism and lifting mechanism with four steel wire ropes. The switching mecha anism drives the grab to close to grab materials. When the grab is closed, the lifting mechanism shall be started immediately to hoist the four evenly loaded steel wire ropes. Discharging only needs to start the switching mechanism, which opens the grab to pour materials.
Except the lifting mechanism, the crane is basically the same e as the bridge crane with hook
