Wheel Service Gets Easier on HD-9 Four-Post Lifts

Wheel Service Gets Easier on HD-9 Four-Post Lifts

The BendPak RJ45W Rolling Bridge Jack adds 4,500 lbs. of frame-engaging lifting capability to compatible four-post lift setups, making it a strong match for HD-9 owners who want more than drive-on vehicle storage and maintenance. Used with a four-post lift, the RJ45W helps raise the vehicle by the frame so the wheels hang free for brake service, tire swaps, suspension work, inspections, and detailing access. This is the bridge jack for users who love the stability and convenience of a four-post lift but still need wheel-service access. A pair of RJ45W rolling bridge jacks can transform an HD-9 style lift from a drive-on platform into a more complete service solution for compact cars, sports cars, garage projects, and daily shop work.
The Standard 4,500-lb. Choice with Practical Clearance

The Standard 4,500-lb. Choice with Practical Clearance

The RJ45W uses a 4.5-inch minimum drive-over height and a 57-inch maximum arm reach, giving it the standard profile and reach for many HD-9 lift applications. For customers who do not need the lower 4.25-inch profile or wider 61-inch reach of the RJ45LP, the RJ45W provides a straightforward 4,500-lb. bridge jack setup with proven four-post lift compatibility. That makes it a smart choice for garages and shops that want dependable wheel-service capability without stepping into a larger-capacity bridge jack than the lift or vehicle requires. It delivers the access most HD-9 users are after: wheels off the runways, frame supported, and service space opened up.

Easy-Roll Positioning with Vehicle-Friendly Contact Pads

The RJ45W comes standard with Easy-Roll wheels designed to fit the runway channels on compatible four-post lifts rated at 7,000 lbs. capacity or greater. The hardened stainless-steel, zinc-plated rollers are built for durability and smooth movement, helping users position the jack quickly beneath the vehicle lift points. Rubber contact pads help protect vehicle surfaces during frame engagement, while stackable adapters increase reach when working with higher-clearance vehicles. BendPak recommends optional frame cradle pads for many trucks and SUVs, giving users another way to match the jack to the vehicle sitting above it.

Independent Air-Hydraulic Power and Three Service Heights

Independent Air-Hydraulic Power and Three Service Heights

The RJ45W includes a high-pressure hydraulic power unit attached to the jack, with an air requirement of 125 psi and 10 to 20 CFM. A foot pedal mounted directly to the unit gives the operator simple control during lifting, keeping bridge jack operation separate from the four-post lift power system. Three lock positions let users fine-tune service height for the work at hand. Whether the job calls for quick tire removal, brake access, or extra undercarriage clearance, the RJ45W gives HD-9 owners a practical way to get more service capability out of the lift they already use every day.
