Bridge Warehouse Cranes – When an application requires hoist coverage over a rectangular area, such as a manufacturing bay, a bridge warehouse crane is required. With it, a hoist can be positioned at any point within the rectangle, permitting lifting, lowering and transportation throughout the area of the warehouse. A bridge crane rides on runways, which are a parallel pair of beams that are attached to the building columns and permit the horizontal movement of the bridge crane structure.
Bridge cranes come in a number of different configurations, such as top running or under running, single girder or double girder. There are relative advantages to each approach, and the proper selection can only be determined once the application and physical constraints are examined.
Gantry Crane – A gantry warehouse crane has a hoist in a trolley which runs horizontally along gantry rails, usually fitted underneath a beam spanning between uprights which themselves have wheels so that the whole crane can move at right angles to the direction of the gantry rails. These cranes come in all sizes and some can move very heavy loads, particularly the extremely large examples of industrial and manufacturing applications.
