Solid-steel safety lock bars engage automatically as the lift rises, allowing technicians to work from multiple locking positions while taking pressure off the hydraulic system during service. Three lock positions help operators choose the working height that best fits the job and reduces fatigue. Stainless-steel pneumatic cylinders release the safety locks during descent with a push-button system operated away from the lift. The system requires a minimum 50 psi, 10 CFM air source at installation and eliminates the need to fight cumbersome release bars or handles.
