Lifting vehicles at this scale demands more than raw hydraulic power. The PCL-18B-6 includes 24-volt safety circuitry, warning lights, audible alarms, emergency shut-off switches, multi-fuse protected electronics, and separate key lock enclosures on each column. Multiple automatic independent safety locks are spaced every four inches, and inverted hydraulic cylinders include integrated safety valves to help prevent uncontrolled lowering in the event of oil pressure loss. Manual safety override valves allow the lift to be lowered during a power outage without manual hand cranks.
