Apparatus and methods for lifting loads are described. The load lift includes a support frame and a lift assembly with main cylinder and at least one standby cylinder connecting a rotatable cross beam with a clamp plate. A rotary actuator assembly is connected to the lift beam to move the lift assembly out of the way while not in use by rotating the lift assembly from a lift position to a standby position.

A hanging device includes an accommodation main body, a sliding assembly, a hook, and the accommodation main body that includes two parallel sidewalls, in which a first vertical path is defined between the two sidewalls. The sliding assembly is movably connected between the two sidewalls to move relative to the main body along the first vertical path. The sliding assembly further includes a sliding rail which defines a second vertical path, and the hook is movably connected to the sliding rail to move relative to the sliding assembly along the second vertical path.

A concrete/steel structure disassembling apparatus which comprises a triangular or T-shaped housing, and a suspension member is pivotably coupled to the triangular or T-shaped housing, and the suspension facilitates suspension of the triangular or T-shaped housing from a crane. At least a concrete/steel pulverizer apparatus is pivotably supported by the triangular or T-shaped housing, and the concrete/steel pulverizer apparatus comprises a pair of concrete/steel pulverizer arms for engaging with a desired section of a concrete/steel structure and pulverizing the same. The concrete/steel structure disassembling apparatus incorporates its own completely independent power module for supplying hydraulic power to the concrete/steel pulverizer apparatus and controlling operation of the at least one pair of concrete/steel pulverizer arms, and the power module is supported by the triangular or T-shaped housing.

Systems and methods for object guidance and collision avoidance are provided. One system includes a location sensor disposed on a movable crane. The system also includes a plurality of sensors disposed on a plurality of objects within a facility. The system further includes a controller having a receiver for monitoring signals transmitted from the location sensor disposed on a movable crane and the plurality of sensors disposed on a plurality of objects within the facility. The controller is configured to generate a travel path for the movable crane to move an object coupled with the movable crane based on the one or more intersection regions and generate an output signal to an alarm device to provide an alert, when at least one object of the plurality of objects is within a predetermined proximity of at least the object being moved by the crane.

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.
