Each PCL-18B column is engineered for real shop movement, with pallet-jack style steering wheels, tandem 8-inch polyurethane-covered steel wheels, sealed roller bearings, extended forks, and multi-width wheel forks with locking pins. Low-mounted power units and cylinders help lower the center of gravity, making the columns easier to maneuver and less likely to feel top-heavy during positioning. Safety systems are built into every column, including 24-volt safety circuitry, warning lights, audible alarms, emergency shut-off switches, automatic independent locks spaced every four inches, and inverted hydraulic cylinders with integrated safety valves. Manual safety override valves also allow lowering in the event of a power outage.
