CARRIAGE BAR

CARRIAGE BAR 3719 0042 87 Functioning as a core part of the drifter carriage, this bar ensures the entire assembly remains stable and square on the feed beam. It helps to smoothly transfer the feed force to the rock drill, maintaining a straight and true path. Proper alignment is critical for efficient drilling, and this bar is fundamental to achieving that.

A bent or heavily worn carriage bar can cause significant operational problems. For example, it can lead to the drifter being misaligned, which results in crooked holes and places high side-loads on the drill string, causing premature wear or breakage. This misalignment also accelerates wear on the carriage slide pieces and the feed beam itself.

During routine maintenance, visually inspect the bar for any signs of bending, cracking, or severe wear. Excessive play in the drifter carriage is often a symptom that this component needs checking. If the bar is found to be damaged, it should be replaced promptly to restore correct drilling alignment and prevent damage to associated parts.
