The RBJ18000 uses a strong pneumatic-hydraulic power unit controlled by a simple foot pedal. The power system is built to raise massive heavy-duty vehicles on compatible four-post lifts, giving the operator straightforward control while keeping the bridge jack operation separate from the lift itself. Three lock positions make the working height adaptable to the job, the vehicle, and the technician. When vehicle clearance, ceiling height, operator preference, or service type changes from job to job, the RBJ18000 gives shops a more flexible way to bring heavy wheels into service range.
