Left collar for Terex CD 225

The left-side collar is a mechanical component used to maintain the axial position of sheaves located at the boom head of the crane. By fixing the sheaves in their designated location along the shaft, the collar prevents lateral movement that could otherwise cause misalignment of the wire ropes. Proper alignment ensures that ropes track correctly through the sheave grooves during hoisting operations, which helps manage the distribution of forces across the lifting system.

This component is specifically designed for use in Terex CD 225 rough-terrain cranes and T340-1XL telescopic cranes. It serves as a fixed point on the sheave shaft to ensure the integrity of the boom's rigging assembly. The part is engineered to fit these specific crane models, maintaining the spacing required for the sheaves to rotate freely without shifting along the axis of the shaft during operation.

Collars of this type function by providing a mechanical stop on a shaft, typically secured to prevent the lateral migration of rotating elements like sheaves or bearings. By keeping these components in their correct orientation, the collar supports the overall alignment of the crane's hoisting system, which is necessary for the controlled movement of loads.
