BendPak RJ45W 4,500 lb Rolling Bridge Jack with Easy Roll Wheels for HD-7, HD-9, and GP-9 Series Four Post Lifts

The BendPak RJ45W is a 4,500 lb capacity rolling bridge jack designed for use with HD-7, HD-9, and GP-9 series four post lifts. When you need to perform tire changes, brake jobs, or suspension work, the RJ45W lets you raise the wheels off the runways for full wheel service. Each jack is over-engineered to hold the weight of an entire vehicle, so when you use two jacks together you get an exceptional margin of safety. Features easy roll wheels that glide inside runway channels, rubber contact pads, stackable adapters for adjustable height, and an air/hydraulic power unit with foot pedal control. Three lock positions let you fine tune your working height. Backed by BendPak's 1 year warranty.

BendPak RJ45W Features

Easy Roll Wheels

The RJ45W comes standard with easy roll wheels that fit onto the runway channels on four post lift models with 7,000 lb lifting capacity or greater. The hardened stainless steel rollers are zinc plated for maximum durability and provide effortless gliding along the runways for easy positioning and adjustability.

Rubber Contact Pads

Durable rubber contact pads come standard with every rolling bridge jack. These pads adjust to engage the frame of your vehicle directly at the manufacturer recommended lift point. Frame cradle pads, sold separately, are a recommended accessory for wide bodied frames like trucks and SUVs.

Stackable Adapters

Some undercarriages require longer reach adapters, so BendPak manufactures stackable adapters to maximize the arm reach on four post rolling bridge jacks. Once your rubber contact pads are positioned under the manufacturer recommended lift points, you may find that high clearance vehicles need extra reach. The stackable adapter set bridges that gap and makes lifting easier.

Air/Hydraulic Power Unit

Welded to the side of each rolling bridge jack is a high pressure air/hydraulic pump that requires 125 PSI and 10 to 25 CFM. It's activated when you press the convenient foot pedal attached to the unit. In seconds your vehicle will be lifted to the desired height. Max operating hydraulic pressure is 2,490 PSI.

Three Lock Positions

Each rolling bridge jack can be raised to three different heights, so whatever your needs are, you can fine tune the height of your jack to meet them. The locks engage automatically as the jack scissor arms raise, and they release simultaneously when the arms are lowered. For maximum access to the undercarriage, raise your car lift to its max height, add the stackable adapters, and raise the rolling bridge jack as high as it will go.
