Abstract
A crane may comprise a mast that includes a base end and a top end located opposite the base end, at least one support beam fixedly coupled to the mast adjacent the top end of the mast, a first runway beam fixedly coupled to the at least one support beam, and a second runway beam spaced from the first runway beam. In some embodiments, the first runway beam defines a first end and a second end, and the mast is located closer to the first end than the second end. The crane may also comprise a bridge movably coupled to the first runway beam and the second runway beam, a trolley movably coupled to the bridge, and a hoist coupled to the trolley. In some embodiments, the crane only comprises one mast.
