Lifting and rigging attachments are used on a crane or hoist between the hook and the item to be lifted. Items include sling release systems, product specific lifters, clamps and grapples.
Lifting blocks are assemblies that consist of a hook or shackle, swivel, bearing, sheaves, sprockets, pins and frame. They are suspended by a hoisting rope or load chain and are designed for a variety of lifting applications.
Shackles are U-shaped pieces of metal secured with a pin or bolt across the opening, or hinged metal loops that are secured with a quick-release locking mechanism.
Turnbuckles are used in rigging to join wire-rope or cable to an anchor point or other length of wire. They have a screw thread to allow for precise length and tension adjustment.
