Omega Single Stage Truck Jack with a 22-ton capacity features a lift height from 9-3/4" to 23-5/8" and uses 90-175 PSI of standard shop air for its air-actuated and hydraulic operation. Omega Air Actuated Hydraulic Axle Jacks are designed to be used vertically for lifting, but not sustaining, loads based on the rated capacity of the jack, not including trailers, houses, or other building structures. This heavy-duty jack features a sturdy, one-piece handle assembly (standard on all Omega Truck Jacks) with a choice of three handle angles for either space saving storage, easy carrying movement, or for access to the lifting point. The unit's user-friendly, self-returning spring minimizes the operator's effort and greatly reduces fatigue, and this unit quickly and effortlessly raises the saddle before power-lifting to the desired height. An inline air filter traps contaminates and protects the air motor for longer life, and a patented, built-in by-pass device protects the hydraulic system from over-pumping damage. Large steel wheels allow for easy positioning and smooth motion, and chrome-plated rams are included. This model includes 1 and 2-1/2 adapters, as well as a heat-treated extension screw, which allows for low pick-up height adjustment and maximum lift height.
