The Atlas® RJ8A air/hydraulic rolling jack has telescoping arms that can be extended over the runways of a four-post lift. The lift pads at the end of these arms can be positioned under the lifting points that are located over the runways of that four-post lift. This rolling jack is equipped with expandable rail supports which adjust to fit between the runways of many different four post above ground lifts. These supports have a unique roller system that allows the rolling hydraulic jack to glide easily under the entire length of the vehicle.
The Atlas® RJ8A rolling bridge jack comes standard with a set of peg style truck adapters which increases the lifting height of the lift pads. These truck adapters will allow the RJ8A to raise most pickup and larger trucks that will sit higher than the average passenger car. The RJ8A rolling hydraulic jack features two solid locking positions that are used when the vehicle is to be suspended above the runways. When the locking positions are engaged, the hydraulic pressure from the lifting cylinder of the jack is eliminated. (These locks act much like a pair of jack stands after you lift a vehicle off the ground with a service jack).
IMPORTANT: The Atlas® RJ8A is designed and engineered to operate on “delivered” air pressure of between 70-115 PSI. If you exceed 115 PSI, you may damage your jack.
