Premier Tech Chronos’ Pneumatic AS/RS Pick-up & Delivery Station Scissors Lift is specifically designed to lift up to 4000 lb. Vertical rods are used to limit the travel of the scissors lift instead of using stops to limit the travel of the scissors’ cam followers, like standard scissors lifts. This feature directly opposes the lifting forces and transfers the lifting energy through the P & D Scissors Lift’s frame, unlike the standard scissors lifts which transfer their forces through the scissors, putting unnecessary stress and wear on the scissors lift’s bushings and cam followers. Premier Tech Chronos' Pneumatic P & D Scissors Lift can also be equipped with pneumatic valves, flow controls, and quick exhaust to customize the lift to your specific lifting or lowering application.
