The Rolling Bridge Jack RJ7100YBK is Rotary’s premium 7,000-lb air-powered scissor jack designed to give technicians instant wheels-free access on a four-post lift. If your shop performs brake service, suspension repairs, tire work, or undercarriage inspections, this bridge jack is one of the most valuable accessories you can add. It dramatically expands what your 4-post lift can do without changing equipment or moving vehicles from bay to bay.

Smooth-rolling urethane wheels make positioning the jack effortless, while the air-powered scissor mechanism delivers quick, controlled lifting every time.
