An '''overhead crane''' is a [[crane]] with a single or multiple girder (bridge girder) bridge carrying a movable or fixed [[hoist]]ing mechanism and traveling on an overhead fixed runway structure.<sup>[http://www.mhia.org/learning/glossary]</sup>


An overhead crane, also known as a [[bridge crane]], is a type of [[crane]] where the hook-and-line mechanism runs along a horizontal beam that itself runs along two widely separated [[rails]]. Often it is in a long factory building and runs along rails along the building's two long walls. It is similar to a [[gantry crane]]. Overhead cranes typically consist of a [[hoist]] to [[lift]] the items, the [[bridge]], which spans the area covered by the crane, and a [[trolley]] to move along the bridge.<sup>[http://www.dearborncrane.com/crane_buyers_guide/bridge_cranes.htm]</sup>
