Sealing Solution Prevents Costly Excavator Downtime
A mine was experiencing leakage of worn, scored shafts in the boom cylinder of an excavator, causing an unplanned shutdown and production loss. Upon inspection, the OEM rubber wiper was found ineffective, leading to scoring of the piston rod.
Our specialist recommended a cylinder upgrade installed on site – including a 21K split wiper with a 11K split stacked set. This significantly improved reliability and postponed the capital repair of a large diameter, heavy duty hydraulic cylinder.
