Rotary Lift's SPOA10 and A10i two-post lifts offer asymmetrical lifting for longer lift life and maximum access to the vehicle's interior. Both lifts feature the patented "Double S" single-piece construction column design providing a channel for the bearings to travel, while maximizing column strength. Both lifts have a 10,000 lb. rated capacity, maintenance-free slider block bearings, easy-position arm restraints and overhead padded switch bars to prevent damage if a vehicle is raised too high
