Lift 2,041-kg. for Full Wheel Service Capability

The RJ45W rolling bridge jack is the DIY’ers dream product, and it’s ideal for any shop with the HD-9, arguably our most popular and versatile car lift. The HD-9 is the lift that many garages prefer because its optional caster kit allows operators to move it anywhere in their shop. Its compact size and reputation for safety mean this is one of the most popular car lifts ever made. Anyone interested in a four-post lift for wheel service should consider the HD-9 complete with a pair of RJ45W rolling bridge jacks.

What is the difference between the RJ45LP and RJ45W?

The RJ45LP and RJ45W rolling bridge jacks are essentially the same except for two specifications: First, the RJ45LP minimum drive-over height is 108 mm and the RJ45W minimum drive-over height is 114 mm. Second, the RJ45LP maximum arm reach is ​1,548 mm wide and the RJ45W maximum arm reach is 1,447 mm wide. Take a look at the RJ45LP Bridge Jack.

Easy-Roll Wheels Come Standard

The RJ45W rolling bridge comes standard with easy-roll wheels that fit onto the runway channels on standard four-post lift models ​3,175-kgs lifting capacity or greater and provide effortless gliding along the runways for easy positioning and adjustability. BendPak rolling bridge jack rollers are made of hardened stainless-steel and zinc plated for maximum durability.

Rubber contact pads

BendPak protects your vehicles by providing a non-marring rubber contact pad on the popular RJ45W rolling bridge jack. The durable design will hold up for many years of heavy use. We highly recommended purchasing the optional frame cradle set for use on trucks and SUVs.

Stackable adapters

Once your rubber contact pads are positioned under the manufacturer-recommended lift points, you may find that high-clearance vehicles are hard to reach. The stackable adapter set comes in handy to bridge that gap and make lifting easier.

High-pressure hydraulic power unit

Attached to the rolling bridge jack is a hydraulic power unit that also features an airline with 125 psi and 10 – 20 CFM. This independent power unit is ergonomically controlled with a foot pedal attached directly to the jack.

Three lock levels

With three lock positions to choose from, it’s easy to find the perfect height to perform wheel and brake service. For additional height, raise the car lift to its max height, add the stackable adapters and raise the rolling bridge jack as high as it will go. Now you have more access to the undercarriage than ever before.
