Sheave for Grove RT 522

The sheave, part number 6-718-000273, serves as a mechanical component within the hoisting and load handling system of Grove industrial cranes. It functions to guide and support the steel wire rope used for lifting and moving heavy loads. By working in conjunction with the wire rope and the winding drum, the sheave allows for the redirection of applied force. In configurations utilizing multiple sheaves, the assembly helps multiply lifting force to manage heavy weights.

This component is compatible with the Grove RT 522 crane model. The contact surface is machined to facilitate the movement of the wire rope, which helps maintain the integrity of the cable during operation. Regular inspection of the sheave groove and bearing surfaces is necessary to ensure the continued safety of crane operations and to prevent premature wear on the wire rope.

Sheaves are passive elements in crane design that manage the path of the hoist line. They are essential for distributing tension evenly across the rope and maintaining the correct fleet angle between the drum and the boom head or hook block.
