The way a crane hook operates can significantly affect lifting safety, productivity, and worker exposure to suspended loads.

Crane hooks are among the most important components in any lifting system. Whether you're moving heavy equipment in a manufacturing facility, handling structural steel on a construction site, or lifting large loads in a warehouse, the crane hook serves as the connection point between the crane and the load.

A shackle is the connector that ties your sling, hook, or wire rope to the load and it's also one of the most commonly mis-specified pieces of rigging hardware on a job site.

Working Load Limit (WLL) is the maximum load a rigging component is rated to bear in normal service, as defined by the manufacturer per applicable ASME standards.

In conventional rigging, releasing a load at the end of a lift requires a rigger to be physically at the load connection point pulling a latch, removing a sling, or manually releasing a shackle.

A rigging block is a pulley assembly used to redirect a rope, wire rope, or synthetic line, or to create a mechanical advantage that reduces the force required to lift or pull a load.

Rigging for offshore and subsea applications requires equipment specifically certified and designed for conditions that onshore industrial rigging does not encounter saltwater exposure.

Learn what rigging equipment is, the main categories used in lifting operations, and how slings, rigging hardware, hoists, and below-the-hook devices work together for safe and efficient load handling in industrial, construction, offshore, and heavy lifting applications.

Moving heavy loads with limited manpower is one of the oldest challenges in construction, marine operations, and industrial work.

A crane on an industrial site, a winch line on a barge, and a sling in a fabrication shop may all use wire rope, but rarely the same variety.
