The RJ45LP uses a high-pressure hydraulic power unit with an air requirement of 125 psi and 10 to 20 CFM. The independent power unit is attached directly to the bridge jack and operated with an ergonomic foot pedal, allowing technicians to raise the jack while keeping their hands free for positioning and setup. Three lock positions make it easier to match the service height to the job. Raise the four-post lift, position the RJ45LP, engage the proper lifting points, and use the bridge jack to lift the wheels clear for tire, brake, and undercarriage service with more control and less compromise.
