The PL6000DC system uses hydraulic lifting with direct-drive cylinder operation, automatic safety lock engagement, anti-fall protection, hydraulic overloading protection, and mechanical safety locks spaced every 4 inches. An electric key switch, automatic shut-off when the operator releases the key, 24VAC operator controls, emergency stop button, pressure relief valve, and upper limit switch all support safer operation. Maintenance-free composite carriage bearings help reduce ongoing service needs, while the overhead power unit supports smooth, quiet hydraulic operation. For facilities expanding an existing PL6000DC parking system, this add-on set keeps the focus where it belongs: more usable parking with controlled operation and fewer headaches.
