The Rotary Lift AR18 Four-Post Alignment Lift gives shops the ability to use a single bay for multiple purposes. With 18,000 lbs of capacity, the AR18 is capable of servicing everything up to and including Class 5 trucks. One runway is adjustable by 3" to allow the lift to be narrowed or widened depending on the vehicle being worked on. The AR18 features two stainless steel turning radius gauges for performing four-wheel alignments. The gauges are compatible with all brands and types of alignment instrumentation, providing seamless integration with existing equipment. For maximum versatility, the lift can be set up to accommodate wheelbases as short as 63" and as long as 162". The extended-length model increases the maximum wheelbase capability up to 198". Two 9,000 lb-capacity rolling jacks are included as standard equipment to enable wheels-free brake, tire, alignment and suspension work.
