Warehouse 20 ton Overhead Bridge Crane Manufacturers

Warehouse 20 ton Overhead Bridge Crane Description

Double girder overhead cranes use two girders to make up the crane to travel on the bridge, supported by end cars/end cars on each side. Typically, double girder overhead cranes are designed in a top-running crane configuration, in which a trolley or open winch trolley runs on a track or track mounted on top of an overhead beam. With a double girder design, double girder

overhead cranes help to gain depth to the beams if the crane is placed between or above the beams. Double girder overhead cranes are widely recommended for heavy material handling capacity with heavier lifts and longer spans. Because of this, the crane components of the double girder overhead crane system, including the hoist trolley and open winch trolley, are more complex in design, which makes double girder overhead cranes more expensive than single girder overhead cranes.
