Full Technical Description
551 998 83 CHAIN, SHORT LINK This short-link chain is the main component responsible for moving the rock drill along the feed beam. It engages with drive sprockets, converting the hydraulic motor's rotation into the linear force needed for drilling. Proper chain function is essential for maintaining a steady feed pressure, which directly impacts drilling speed and the straightness of the hole.
Over time, the high tensile loads during drilling can cause the chain to stretch and wear. A stretched chain causes the drifter to feed unevenly, which can lead to stuck drill steel or premature bit failure. If a link fails completely, the entire drilling operation stops, leading to unplanned downtime and lost production.
Inspect the chain regularly for proper tension, signs of cracking on the links, and excessive wear. Listen for any grinding or popping sounds from the feed system during operation, as this can indicate a worn chain or sprockets. When replacing the chain, always check the condition of the drive sprockets as well.
