Omega Long-Chassis, High-Reach Service Jack with an air-actuated/manually-operated design and a 20-ton capacity features a lift height from 13" to 39-1/2". Omega Hydraulic Service Jacks are designed to lift one wheel or axle of a vehicle for servicing or repairing vehicle components and should be used in conjunction with jack stands. The effortless air operation of this unit, using Omega's patented Air TurboMotor, will greatly reduce operator fatigue and speed up the efficiency of garage work, and the high-speed Air TurboMotor is equipped to raise the load to the desired height efficiently, effortlessly, and safely. A heavy gauge, steel frame helps prevent distortion or twisting, and the handle-actuated release valve provides precise, metered load control at any desired lowering speed. The jack's wide stance and low center of gravity provide optimum stability under load stress, and a convenient foot pedal allows for fast and safe no-load lifts.
