The 551 643 74 CARRIAGE is the assembly that holds the rock drill and guides it along the feed beam. It ensures the drifter remains stable and correctly aligned, which is critical for straight drilling and reducing wear on your consumables.

Full Technical Description
551 643 74 CARRIAGE Functioning as the interface between the drifter and the feed system, the CARRIAGE assembly slides along the feed rail. It supports the full weight of the rock drill and transmits the feed force necessary for drilling. This guidance is essential for maintaining drilling accuracy and ensuring that impact energy is transferred efficiently from the drill steel to the rock face.
Wear on the CARRIAGE's slide pieces or frame can cause the drifter to become loose on the feed. This misalignment is a common source of problems, such as difficulty collaring a new hole and accelerated wear on the shank adapter and drill rods. A worn CARRIAGE puts significant strain on the entire feed system, leading to lower productivity and a higher risk of component failure.
A key symptom of a worn CARRIAGE is visible play or a rocking motion of the drifter as it sits on the feed. During routine checks, inspect the wear strips and replace them before they wear down to the metal. Keeping the feed rail clean also helps extend the life of the CARRIAGE.
