Hooks are one of the most common types of rigging hardware used in various industries, including construction, shipping, and entertainment. They come in various sizes, shapes, and materials, depending on the application and load requirements.
Here are some of the most common types of hooks and their uses:
Clevis hooks: Clevis hooks have a U-shaped opening on one end that can be attached to a chain, rope, or other rigging equipment with a clevis pin. They are commonly used in construction and industrial applications for lifting heavy loads.
Grab hooks: Grab hooks have a narrow throat and a sharp point on one end that can grab onto the chain links or wire rope. They are commonly used in construction and transportation industries to secure loads to flatbed trailers or trucks.
S hooks: S hooks have a curved shape and two openings on each end that can be used to attach to chains, ropes, or other rigging equipment. They are commonly used in the entertainment industry to hang lighting fixtures, sound equipment, and decorations.
Eye hooks: Eye hooks have a looped end that can be attached to chains or ropes with a shackle or other hardware. They are commonly used in construction and industrial applications for lifting and securing heavy loads.
Swivel hooks: Swivel hooks have a rotating eye and a hook that can rotate 360 degrees, allowing for free movement of the load without twisting or tangling the rigging equipment. They are commonly used in fishing and boating industries to secure fishing lines and anchor ropes.
Hooks should be selected based on the load requirements, size, and shape of the rigging equipment, and the environment in which they will be used. Proper inspection, maintenance, and use of hooks are critical to ensure safe and efficient lifting and securing of loads.
