CEMENT FEED HOSE

163 285 71A CEMENT FEED HOSE Serving as the main conduit in the grouting system, this hose delivers the cement mixture required for setting rock bolts. It connects the grout pump, often located on the rig's chassis, to the bolting head at the end of the feed beam. Its flexibility allows it to follow the movements of the boom and feed while maintaining a consistent flow of material for effective ground stabilization.

The integrity of this hose is directly linked to both operator safety and the quality of the ground support. A sudden failure can spray grout, creating a hazardous work area, and can result in an improperly grouted rock bolt, compromising tunnel stability. Consistent, uninterrupted grout flow through a reliable hose is essential for achieving the designed strength of the rock reinforcement and preventing delays in the drilling cycle.

Look for signs of wear such as abrasion on the outer cover, soft spots, or bulging, which often precede a burst. Leaks at the hose fittings are also a clear indicator that replacement is needed. Before starting a bolting cycle, always perform a quick visual check of the hose, especially at bend points and connection areas. Never attempt to repair a damaged grout hose; always replace it to ensure safety and proper function.
