Cat® Support Pins are used to limit the motion of Grapple arms in Cat® machine. It backs the arms on one side by sliding contact and as a result when the arms opens and closes, this pin rotates. This will limit the opening of the arms in backward direction. It also acts as an additional support to the grapple, when it carries a load.

Genuine Cat® Pins are specifically designed to operate as a system to deliver the performance you expect. Caterpillar design engineers match the right combination of dimensions, materials, heat treatment, surface treatments and finish to each part to enable them to work and wear effectively with all the other neighboring and dependent parts. Cat® Linkage Pins are machined from high grade steel bar and hardened for exceptional strength and wear life. They work as part of the system for your specific Cat® machine and are tested and proven in the world's most severe applications. They result in outstanding strength and fatigue life, superior resistance to abrasive wear, and exceptional protection against pin galling, even in high-load conditions.

Application: Cat® Grapple Support Pins are designed for conditions that require superior load carrying capacity, strength and wear resistance for longer life. Cat® Pins are the top choice for maximum performance in demanding applications. Consult your owner's manual or contact your local Cat® Dealer for more information.
