CUSHION

CUSHION 6060 0025 71 A cushion plays a vital role in managing the dynamic forces within a rock drilling rig. These components are typically found in areas designed to absorb impact or dampen movement, such as the feed system's end stops or within the drifter mechanism itself. Their primary function is to absorb kinetic energy, preventing metal-on-metal contact and reducing the transmission of shock loads throughout the machine's structure. This protection is essential for components like the feed beam, rotation unit, and even the boom.

The presence of a functional cushion directly contributes to the overall reliability of the drilling operation. By effectively absorbing shocks and vibrations, it prevents premature fatigue and wear on more expensive and complex assemblies. This not only extends the service life of critical parts but also helps maintain consistent drilling performance, preventing erratic movements or sudden jolts that can disrupt the drilling process. Ultimately, a well-maintained cushion supports safer operations by minimizing unexpected mechanical stresses.

When a cushion starts to wear out, harden, or crack, you might notice increased vibration, unusual banging noises, or accelerated wear on adjacent components. For instance, if a feed system cushion fails, the drill carriage could hit the end of the beam with excessive force, potentially damaging the feed motor or the beam itself. Regular visual inspections are key; check for signs of deformation, tears, or excessive compression. Replacing a worn cushion promptly is a simple yet effective way to prevent more significant and costly repairs down the line.
