Sheave assembly for Terex AC 200

The sheave assembly, identified by part number 3221140, serves as a component within the hoisting system of the crane. Its primary function involves guiding the steel wire rope through the boom and head assembly, which allows for the distribution of loads and manages friction during lifting and lowering operations. This component ensures that the wire rope moves in a controlled path throughout the crane's rigging system.

This part is compatible with the Terex AC 200 crane. It is manufactured to meet the specifications required for integration into the hoisting assembly of this specific model. The assembly includes the sheave and necessary components to maintain the alignment of the wire rope during operation.

Sheaves are used in heavy machinery to redirect wire ropes and change the mechanical advantage of a lifting system. By providing a grooved surface for the rope to travel along, the sheave minimizes stress on the cable and maintains the structural integrity of the hoisting system. Regular inspection of the sheave groove and internal bearings is necessary to ensure the continued operation of the crane's lifting functions.
