Contamination Control: Critical for longevity, as ingested contaminants are the primary cause of internal cylinder damage.
No Drift / Held Load Security: The superior sealing ensures the boom will not settle or creep down unintentionally, even when holding a heavy load at height. This is a critical safety and performance feature.
Maintained Efficiency: Minimizes internal leakage, ensuring that hydraulic power is converted into productive lifting force, not wasted as heat.
