4 Post Rolling Bridge Jack

When you’re looking for a versatile, convenient, and highly effective way to service your car, truck, or fleet of vehicles, 4 post sliding bridge jacks can make all the difference. These innovative jacking systems are designed to integrate seamlessly with a 4 post lift, transforming your shop or home garage into a fully functional service bay. By adding a sliding bridge jack to your existing lift setup, you gain the ability to perform everything from tire rotations and brake jobs to suspension work and other under-vehicle maintenance—all without ever leaving the safety and efficiency of your four post lift. Below, we’ll dive into what makes 4 post sliding bridge jacks so special, the benefits of adding them to your garage, and how Redline Engineering and Redline Stands can help you secure the right equipment for your needs.

 

What Are 4 Post Sliding Bridge Jacks?

 

A 4 post sliding bridge jack is a specialized jack designed to slide along the runways of a 4 post car lift. Rather than having to move your vehicle to a separate workstation or use multiple floor jacks, you simply position the bridge jack under the vehicle’s lifting points. Once in place, you can raise the bridge jack with either an air or hydraulic pump, effectively lifting the wheels off the runways. This creates easy access to the tires, brakes, and suspension components. For this reason, sliding jacks are often called rolling bridge jacks or rolling jacks, as some designs can roll or slide from front to back, giving you excellent positioning options along the length of your lift.

 

Key Benefits of Sliding Bridge Jacks

 

  1. Increased Versatility: By incorporating a bridge jack for a 4 post lift, you can handle a variety of automotive maintenance tasks. Need to swap out brake pads or inspect wheel bearings? Simply slide the rolling jack into position under the appropriate axle or corner of the vehicle and lift. This flexibility helps you handle more jobs in-house, whether you’re a professional shop owner or a dedicated do-it-yourselfer.
  2. Improved Efficiency: Time is money in any shop setting. A 4 post lift with sliding jacks allows you to complete tasks faster, since you’re not juggling floor jacks, jack stands, or repositioning the vehicle multiple times. Instead, the integrated bridge jack raises the wheels quickly and safely, letting you get the job done with minimal downtime.
  3. Enhanced Safety: A 4 post rolling bridge jack is engineered to fit the precise dimensions of your lift’s runways. This close fit, combined with robust steel construction and secure locking features, provides a stable platform for working on your car or truck. Many heavy duty rolling bridge jacks even include safety locks to ensure the jack stays at the set height while you work underneath the vehicle.
  4. Space Savings: Another critical advantage of sliding or rolling jacks for 4-post lifts is that they don’t occupy additional floor space when not in use. You simply roll or slide them out of the way along the runways, saving valuable shop real estate for other equipment and tools.

 

Key Features to Look For

 

  • Capacity and Compatibility: Before buying a sliding bridge jack for a 4 post lift, confirm it’s rated to handle the weight of the vehicles you plan to service. If you handle heavier vehicles, like trucks, you may require a 4 post truck lift with jacks that offer a higher lifting capacity.
  • Adjustable Width: Different vehicles have different track widths. Look for 4 post bridge jacks with adjustable pads or arms so you can align them precisely with the OEM lifting points.
  • Air or Hydraulic Operation: Many bridge jacks are powered by compressed air, offering quick up-and-down movement. Some models integrate hydraulic systems. If you prefer a smooth, controlled lift, opt for a hydraulic bridge jack or an air jack for a 4 post lift with variable speed control.
  • Locking Mechanisms: A reliable lock ensures your center jack for a 4 post lift stays secure at the chosen height. This feature can also help prevent accidental lowering while you’re working.
  • Quality Construction: Always look for high-quality steel construction and top-notch welds. A well-built 4 post lift air jack will last for years without bending, warping, or experiencing leaks.

 

How to Use a 4 Post Sliding Bridge Jack

 

  1. Position Your Vehicle: Drive or roll your vehicle onto the 4 post car lift. Ensure it’s centered and that the tires are properly supported by the runways.
  2. Secure the Lift: Once the vehicle is in place, raise the 4 post lift to the desired working height, using the lift’s built-in safety locks to keep it stable.
  3. Slide the Bridge Jack: Move the sliding jack along the runways to the point where you need to lift the vehicle—front, rear, or even just one corner. Adjust the pads to align with the designated lifting points on the vehicle’s chassis.
  4. Lift the Vehicle: Activate the rolling bridge jack—be it an air jack, hydraulic jack, or combination system—until the wheels clear the runways. Make sure the jack’s safety lock engages, ensuring a stable support before you begin any work.
  5. Perform Maintenance: With the wheels suspended, you now have clear access for tire rotations, brake inspections, suspension repairs, and more. When you finish, lower the vehicle gently, release the sliding jack lock, and roll or slide the jack out of the way.

Additional Considerations

  • Safety Training: Even the best rolling air jack or 4 post lift center jack won’t do you any good if you don’t follow proper safety procedures. Always wear appropriate protective gear and ensure you understand how to operate the lift and jack before starting any maintenance work.
