BendPak RJ45W 4-Post Rolling Bridge Jack
Lift 4,500 lbs. 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 4.25″ and the RJ45W minimum drive-over height is 4.5″. Second, the RJ45LP maximum arm reach is 61″ wide and the RJ45W maximum arm reach is 57″ 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 7,000-lbs 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.

Been using it for a few weeks now, holding up well. Instructions could be clearer but it wasn't hard to figure out.
