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.
