BASE PLATE

819 022 69 MANIFOLD BODY, VALVE Serving as the structural foundation for the rock drill cradle, this plate creates a flat and stable mounting point on the feed beam. Its primary job is to maintain the precise alignment between the drifter and the feed, ensuring that drilling forces are transmitted straight down the drill string. Proper alignment is critical for preventing excessive wear on both the drifter's slide bars and the feed components.

A bent or cracked BASE PLATE directly impacts drilling accuracy and equipment health. Misalignment can cause the drill steel to bind in the hole, leading to slower penetration and increased stress on the rotation unit. Over time, the constant vibration and shock loads of drilling can fatigue the metal, making regular inspection a key part of preventing unexpected downtime and larger mechanical failures.

Look for any signs of cracking, especially around the mounting bolt holes. Use a straight edge to check for flatness if you suspect the plate has been bent from an impact. Always replace a damaged plate to restore the assembly's integrity. Ensure all mounting hardware is correctly torqued during installation to prevent movement and uneven loading.
