Full Technical Description
880 920 69A LINK, CHAIN As a key piece of the feed system, this link joins the ends of the feed chain together. This chain is responsible for pulling the rock drifter along the feed beam, applying the necessary pressure for efficient drilling. The link must handle the high tensile forces involved in both advancing the drifter and retracting it from the hole.
The integrity of this single link is essential for the entire drilling operation. If it fails, the feed chain breaks, immediately halting progress and potentially causing the drifter to slide down the feed. A worn link can also lead to jerky feed motion, which reduces penetration speed and puts extra stress on the drill string and bits.
During routine maintenance, look for any signs of stretching, cracks, or wear on the chain links, especially the connecting link. An unusually slack chain or a clicking noise from the feed can indicate a problem. When installing a new link, ensure it is properly secured and check the overall chain tension to prevent premature failure.
