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.
Claims20
A crane, comprising:
- a mast extending along a vertical direction, the mast comprising a base end and a top end located opposite the base end;
- at least one support beam coupled to the mast;
- a first runway beam extending along a horizontal direction perpendicular to the vertical direction and fixedly coupled to the at least one support beam;
- a second runway beam extending along the horizontal direction and fixedly coupled to the at least one support beam, the second runway beam spaced from the first runway beam;
- a bridge movably coupled to the first runway beam and the second runway beam, the bridge arranged and configured to move between a first location and a second location of the first runway beam and the second runway beam;
- a trolley movably coupled to the bridge, wherein the trolley is arranged and configured to move between a first location and a second location of the bridge;
- and
- a hoist coupled to the trolley, the hoist configured to lift and lower an object with respect to the trolley.
A method of using a crane to lift and lower an object, the method comprising:
- detachably coupling the object to a hoist, wherein the hoist is at least one of mechanically and electrically coupled to a trolley;
- electrically coupling the hoist to a power source;
- and
- engaging the hoist, via the power source, to lift and lower the object,
- wherein the trolley is movably coupled to a bridge such that the trolley is arranged and configured to move between a first location and a second location of the bridge, the bridge is movably coupled to a first runway beam and a second runway beam such that the bridge is arranged and configured to move between a first location and a second location of the first runway beam and the second runway beam, the first runway beam and the second runway beam are fixedly coupled to at least one support beam, and the at least one support beam is coupled to a mast.
