PEDAL ASSEMBLY

770 171 49A PEDAL ASSEMBLY This plate assembly functions as a key interface and guide, typically located within the drifter cradle or feed system. Its main job is to maintain the correct alignment between the rock drill and the feed beam. By providing a stable and true surface, it ensures that drilling forces are directed straight into the rock face without side loading.

Wear or damage to this assembly can have a significant impact on overall drilling performance. For example, if the plate wears unevenly, the drifter can become misaligned, leading to excessive stress on the feed beam, cradle, and drill string. This not only reduces drilling accuracy but also accelerates wear on more costly components, leading to unplanned downtime.

Look for signs of deep scoring, cracks, or warping during regular inspections. Excessive play or a chattering sound as the drifter travels along the feed can also indicate a worn plate. Replacing a worn assembly is a straightforward task that prevents cascading failures and maintains the rig's operational integrity.
