Abstract
A C-hook for lifting heavy coils, such as coils of steel, includes a lifting frame which has an upper arm that is formed with a lifting point in the form of integrally formed lug for receiving a lifting hook of a crane. A counterweight is fixed at a forward end of the upper arm. The lower end of the frame is formed with a slide that receives a slideable load support member in the form of foot. The foot has a forward front foot end for penetration of the lumen of a coil to be lifted. The opposite, rearward end of the foot is mechanically interlinked by a mechanical linkage to a coil backstop member. The mechanical linkage includes a lever arm, which pivots about a fixed pivot point that is fast with the frame. The foot and backstop member facilitate the balanced transportation of steel coils of varying widths.
