9,000 pound capacity scissor lift. Uni Lift incorporates the Nussbaum NT hydraulic system with precisely machined steel, and the lowest profile of comparable capacity scissor racks making this lift specially suitable for above ground installation. High performance oil-submerged power unit ensures a quiet operation and fast lifting and lowering times. No mechanical connection between the platforms allows free access between the scissors. Cylinders are hard chromed to increase durability and life. Mechanical locks standard for alignment leveling at three positions. Safe-T-Lower engages slow lowering and warning tone at 12 inches.
