The Rolling Bridge Jack RJ9100Y is Rotary’s 9,000-lb air-powered scissor jack designed specifically for SM18 and ARO22 four-post lifts. Built for shops that regularly service larger SUVs, trucks, EVs, and commercial vehicles, this bridge jack gives technicians true wheels-free lifting for brake work, suspension jobs, tire service, and undercarriage repairs—all without moving the vehicle to another bay. Smooth-rolling urethane wheels make positioning the jack easy, while adjustable rail engagement ensures a secure fit on heavy-duty Rotary lift runways. With its strong lifting capacity and included rubber adapter blocks, the jack instantly expands what your four-post lift can do.
