Electric grab Bridge Crane is mainly comprised of box-shaped bridge, grab crab (Grab Bucket), trolley travelling mechanism, cab and electric control system. The load handing device is the grab which is able to capture bulk materials.
The grab cab has switching mechanism and lifting mechanism. The grabs are separately hung over the switching mechanism and lifting mechanism with four steel wire ropes. The switching mechanism drives the grab to close to grab material. 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 Overhead Crane is basically the same as the bridge crane with hook.
