Types of Bridge Jacks Used in Automotive Lifts If you’ve worked around four-post lifts for any amount of time, you already know a bridge jack changes what the lift can actually do. Without one, the vehicle stays sitting on its wheels. Once a bridge jack is added, you can lift the axle or frame and start doing wheel, brake, suspension, and tire work properly. The thing is, not all bridge jacks are the same. Different workshops use different setups depending on the kind of vehicles they handle and how heavy the daily workload is. Some are built for lighter automotive jobs, while others are designed for trucks, buses, and commercial vehicles where the weight is on a completely different level.
