About rolling bridge jacks

A rolling bridge jack sits across the runways of a four-post lift and raises the vehicle off them, so the wheels can come off. Air-over-hydraulic operation means it lifts from shop air with no separate power unit.

What to check before you order

• Runway width and rail profile — a jack must match the lift it rides on
• Minimum pad height against the ground clearance of your lowest vehicle
• Capacity, remembering a jack carries one end of the vehicle, not all of it
• Air supply: most units want 100–150 psi at a reasonable volume
