The PCL-18B-4 combines an enclosed electric-hydraulic power system, 24-volt safety circuitry, multi-fuse protected electronics, and standard off-the-shelf PLC components that help reduce service complexity compared with proprietary control systems. It is built for simple operation, long service life, and minimum maintenance. Each column includes warning lights, audible alarms, emergency shut-off switches, independent automatic safety locks, and inverted hydraulic cylinders with integrated safety valves. Heavy-duty steel carriage rollers, extended forks, wheel-fork locking pins, forklift pockets, and durable powder coat construction help the system stand up to daily commercial shop use.
