Abstract
A gap jumping overhead crane for use with two parallel runways each having a first and second end and a gap between their first and second ends. The crane has a hoist mounted on a bridge having opposing ends that extends between the two parallel runways. The bridge is slidably mountable to the two parallel runways at each of its ends by an end truck. Each end truck has two ends and at least three load wheels attached to the end truck. At least two of the load wheels are separated by a distance greater than the size of the gap to permit the crane to cross the gap in the runways.
