BOOM SWING

770 054 88 BOOM SWING Mounted at the boom's main pivot point, this hydraulic cylinder is a core actuator in the positioning system. It converts hydraulic pressure into the powerful, controlled motion required to swing the boom assembly horizontally. This function allows the operator to accurately aim the feed beam across the rock face, which is fundamental for drilling a proper blast pattern without repositioning the entire machine.

Proper function of the swing cylinder is essential for both productivity and safety. Any internal bypassing or external leaks will result in slow, jerky movements and an inability to hold a set position. For example, if the cylinder drifts under load, the operator constantly has to make corrections, which slows down the drilling cycle and can lead to misaligned holes. A sudden failure could cause uncontrolled boom movement, creating a serious hazard underground.

Common signs of wear include visible oil leaks around the piston rod seal or a boom that won't stay put. If you notice the boom swinging slower than usual or hear a hissing sound from the cylinder during operation, it likely needs attention. Regular checks for leaks and physical damage are important. Replace the cylinder or its seals promptly to avoid unplanned downtime and maintain safe operation.
