Lifting Hooks

Rigging hooks are essential for many rigging applications and vary widely when it comes to function, design, and capacity. But, essentially, every rigging hook is composed of two main elements: a base, where it is attached to the chain or rope, and the actual hook-shaped part where it holds the load. There are three common types of base (eye, clevis, and swivel) and thee common types of hook (grab, slip, and self-locking).

Grab hooks have tighter throats designed to securely “grab” the load. Slip hooks have wider openings, so they’re usually easier and faster to load, and some include a snapping latch to help keep the rope on the hook. Self-locking rigging hooks provide greater safety than latched hooks because they automatically close and lock under load. In order to release a self-locking rigging hook, the load must be grounded.

When it comes to rigging hook bases, eye hooks are simple and reliable, but relatively unchangeable after installation. Clevis hooks attach to the rope via a clevis and pin system, making them easier to transfer from one application to another. And swivel hooks have the capacity to rotate, making them the ideal choice when rotation is expected.
