European Type Double Girders Electric Overhead Traveling Crane is mainly comprised of the box-shaped bridge, grab crab, trolley traveling mechanism, cab, and electric control system. The load-handling device is the grab which is able to capture bulk materials.
The grab crab has a switching mechanism and a 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 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 for the lifting mechanism, the crane is basically the same as the bridge crane with a hook.
A double-girder overhead crane with a hook is usually used in the workshop to lift material and equipment. It mainly consists of a Trolley, bridge frame, long traveling unit, hook and wire rope, cabin and electric control system, etc.
