CHAIN FEED ASSEMBLY

550 308 90BA CHAIN FEED ASSEMBLY Forming the main guide rail for the drifter, this feed channel assembly is the backbone of the entire feed beam. It provides a straight, rigid path for the drifter cradle to travel on during both drilling and retraction, ensuring force is applied directly into the rock.

Correct alignment of the feed channel is critical for drilling accuracy and preventing component damage. A bent or heavily worn channel can cause the drill string to bind in the hole, leading to poor performance and an increased risk of breaking drill steel. It also puts unnecessary side-load on the drifter's internal components.

Visually inspect the channel for straightness and check the guide surfaces for deep grooves or excessive wear. Any significant bending or damage warrants replacement to avoid costly failures of the drifter and drill tools. Keeping the channel clear of rock chips and debris will also extend its service life.
