Hook Blocks (Crane Bottom Blocks)

Hook blocks, also known as crane bottom blocks, are below-the-hook lifting devices widely used in industrial operations to handle heavy loads with precision and safety. These rugged assemblies are reeved into the crane and feature a hook that lift various types of loads. By reducing strain on the hoist line and enabling smooth, controlled lifting and lowering of loads, hook blocks play a pivotal role in optimizing productivity and ensuring workplace safety.

Avon Engineering crane hook blocks are designed and engineered to service specific application needs. Sheave configuration, capacity, special control requirements, and unique reeving patterns can be included to improve your crane operation. The motor-driven or non-driven 360° rotating crane hook block permits the crane operator to position heavy or awkward loads in less accessible work areas.
