Atlas RJ45A 4,500 lb Air/Hydraulic Rolling Bridge Jack

The Atlas RJ45A is a 4,500-lb air/hydraulic rolling bridge jack that turns a four-post lift into a wheels-free service bay. It rolls the full length of the lift on nylon rollers and a steel wheel, so you can position it under either axle, raise the vehicle off the runways, and get to tires, brakes, and suspension work without repositioning the car.

The RJ45A is sized for 9,000-lb-capacity four-post lifts, including the Atlas Garage Pro9000. Its adjustable support arms fit runway openings from 36 to 54 inches, and the lift arms extend from 30 to 60-1/2 inches at the center of the pad to reach factory lifting points across a range of wheelbases. A scissor mechanism keeps the lift level as it rises.

Operation is air over hydraulic on 70–115 PSI of shop air (an external air supply is required and not included). Two safety locking positions hold the load mechanically once the vehicle is raised — much like a pair of jack stands — so hydraulic pressure is not carrying the vehicle during service.

Will it fit my four-post lift?

The adjustable support arms fit runway openings from 36 to 54 inches, and the lift arms extend from 30 to 60-1/2 inches at the center of the pad. It is designed for 9,000-lb-capacity four-post lifts such as the Atlas Garage Pro9000.

Do I need an air compressor?

Yes. The RJ45A runs on 70–115 PSI of shop air, and an external air supply is required and not included.

How high will it raise a vehicle off the runways?

Maximum lifting height is about 11-3/4 inches with no adapters and 18-1/2 inches with the tallest adapters installed. Actual height varies by lift.
