TANK ASSEMBLY

770 258 94F TANK ASSEMBLY Functioning as the drifter's cradle, this traverse assembly guides the rock drill along the feed beam. It provides a stable, low-friction connection that is essential for maintaining proper alignment of the entire drill string. Without a solid guide, drilling energy is lost and collaring holes accurately becomes difficult.

Wear in this assembly directly impacts drilling performance and the service life of other components. If the internal guide strips or pads wear out, the drifter can become loose, causing it to rock on the feed. This misalignment puts extra stress on the shank adapter, drill steel, and the feed mechanism itself, leading to faster wear and potential failures.

Listen for rattling sounds from the feed during operation and visually check for any play between the drifter and the beam. If you can move the drifter side-to-side by hand, it's a clear sign that the internal wear parts of the assembly need inspection and likely replacement.
