CLAMP BAND

090 778 28 FASTENING PIECE A CLAMP BAND provides the necessary tension to hold flexible components securely onto rigid fittings. On a rock drill, you'll find these clamps in many places, from securing hydraulic return lines to fastening the protective dust boot at the front of the drifter. Its main job is to create a seal that prevents fluid from leaking out or abrasive rock dust from getting in.

Proper clamping force is essential for the machine's reliability. For example, if the clamp on the drifter's front boot becomes loose, abrasive drilling dust can work its way into the shank adapter and front bushing, causing rapid wear. A failed clamp on a lubrication or coolant line can lead to component overheating and seizure, resulting in costly, unscheduled downtime.

Check for loose or corroded clamps during regular walk-around inspections. Any signs of fluid weeping from a hose connection or a cracked clamp band mean it's time for a replacement. When servicing a hose or boot, it is always good practice to install a new clamp to ensure proper sealing tension.
