Double Girder Overhead Crane is such that its bridge moves on elevated tracks, also called overhead traveling crane or Bridge Crane . A bridge has its bridge longitudinally move along the elevated tracks laid at both sides and its carriage laterally move along the tracks laid on the bridge to make a rectangular working scope. In this way, the room below the bridge can be made fully use of while being free of hindrance of equipment on the ground.
It is used together with the Electric Winch . It is a Double Girder Bridge Crane, whose small car is moving on the railway of the main girder.
Crane Girder:
The crane girder is of welded girder construction. This result in lower dead weight with a high degree of vertical and horizontal rigidity and small wheel loads being transmitted to the crane runway!
Lifting mechanism -- electric winch :
Electric winch is composed of reducer, brake, motors, drum and trolley frame , which can be mounted on bridge crane , Gantry Crane is to improve labor efficiency, improve working conditions for machinery .
