Racer roller for Locatelli GRIL 827

The racer roller, part number 5127305, functions as a guide within the telescopic boom assembly of Locatelli mobile cranes. It supports the movement of the boom sections, allowing them to slide during extension and retraction cycles. By maintaining proper alignment between the sliding surfaces, this component helps ensure the boom operates smoothly without binding or erratic movement during load positioning tasks.

This component is compatible with the Locatelli GRIL 827 and GRL827 crane models. It is installed within the boom structure to manage the mechanical interface between the moving sections. Regular inspection of these rollers is standard practice for crane maintenance to monitor for surface wear or deformation that could affect the telescopic operation of the boom system.

In telescopic crane design, rollers of this type are used to distribute the load of the boom sections across the internal wear pads or tracks. They minimize friction during operation, which is necessary for the precise control of the boom length. Proper function of the roller assembly ensures that the crane can extend and retract its boom under load while maintaining structural stability throughout the lifting process.
