ZOOM CYLINDER

166 157 04 ZOOM CYLINDER 80/50 A hydraulic cylinder like this one is a fundamental workhorse in any underground drilling rig. It's responsible for converting the hydraulic power from the machine's system into the linear push or pull needed for many operations. You'll typically find these cylinders on the feed system, controlling the advancement and retraction of the drill string, or on the boom, enabling precise positioning of the drifter for accurate hole placement.

The proper functioning of a cylinder directly impacts the rig's productivity and safety. If a feed cylinder isn't working correctly, the drill bit might not advance smoothly, leading to slower penetration rates or even jamming. Similarly, a worn boom cylinder can cause the drifter to drift out of position, affecting hole accuracy and potentially creating unsafe conditions. A well-maintained cylinder ensures stable, predictable movement, which is vital for both operational efficiency and the safety of personnel working around the machine.

Common signs of a failing cylinder include external oil leaks around the rod seals, slow or jerky movement, or a noticeable loss of force in its operation. Internal leaks, where fluid bypasses the piston, can also reduce its effectiveness without visible external signs. When these symptoms appear, it's usually time to inspect the cylinder thoroughly. Often, replacing the seal kit can resolve minor issues, but if the cylinder barrel or rod is damaged, a complete replacement is the most reliable solution to restore full functionality and prevent further downtime.
