Upper rear wear pad for Grove cranes

The upper rear wear pad, part number 6671000870, is a component installed within the telescopic boom system of Grove cranes. It functions as a bearing surface that separates the sliding boom sections, absorbing the friction generated by the constant movement of the boom during operation. By providing a controlled contact point, it prevents direct metal-to-metal contact between the structural steel sections of the boom assembly.

This component is compatible with various Grove telescopic crane models, including rough-terrain, all-terrain, and truck-mounted configurations. Proper installation of this wear pad ensures that the boom sections maintain correct alignment and spacing, which is necessary for smooth extension and retraction cycles. Regular inspection and replacement of these pads are standard procedures in crane maintenance to prevent excessive play or binding within the boom structure.

Wear pads are engineered to act as sacrificial elements in heavy machinery. In telescopic booms, they facilitate the sliding motion of the inner sections while supporting the vertical and lateral loads applied to the boom. By managing the clearance between sections, these pads help maintain the structural integrity of the crane and ensure that the hydraulic extension system operates within designed load parameters.
