Cotter pin for Terex CD 225

The cotter pin 1222-239 functions as a mechanical fastener within the boom assembly of Terex cranes. It is specifically designed to secure the position of pins or shafts associated with the internal boom pulleys. By preventing these pins from shifting or sliding out of their housing, the component ensures the pulleys remain properly aligned to guide the hoist cables during operation.

This part is compatible with Terex CD 225 and T340-1XL crane models. It is intended for use in systems where pulley retention is required to maintain the integrity of the boom assembly. Proper installation of this fastener is necessary to keep the pulley shafts fixed within their designated mounting points.

In crane systems, cotter pins serve as a locking mechanism for clevis pins or other shaft-retaining hardware. They are inserted through a pre-drilled hole in a shaft and then spread or secured to prevent the shaft from backing out of its assembly. This simple retention method is standard for ensuring that rotating or stationary components, such as sheaves and pulleys, remain securely attached to the crane structure during heavy lifting tasks.
