Abstract
A crane for lifting and transporting a load such as a heavy metal coil. An overhead winch lifts and lowers a load carriage and the load attached thereto, and a powered wheeled trolley moves the load horizontally above a floor. Attached to the carriage is a clamp, which engages the coil through its center aperture and its periphery. The clamp has two jaws, one movable with respect to the other, the movable jaw also having a movable gripping surface that moves on an inclined surface of the movable jaw towards the fixed jar to ensure a tight wedging engagement of the load. The jaws and gripping surfaces provide a nonpowered, mechanically firm grip on the load once it has been engaged by the jaws. The coil may be lifted with the jaws when its center aperture is vertically or horizontally disposed, and the load may be placed for storage in either position as well.
