Description
Atlas® 412A – Commercial-Grade 12,000 lb. 4-Post Alignment Lift
The Atlas® 412A is a commercial-grade, 12,000 lb. capacity four-post alignment lift designed for professional service centers and high-volume automotive shops. Built to exceed industry standards, the 412A delivers exceptional strength, reliability, and performance for years of dependable operation.
Engineered with structural and cosmetic refinements typically found in lifts costing thousands more, the Atlas® 412A stands out as one of the best values in its class. Each unit is rigorously tested to ensure flawless operation at full rated capacity, meeting the needs of alignment technicians and general repair professionals alike.
The lift utilizes a high-strength cable system combined with an oversized hydraulic cylinder mounted beneath the runways, powered by a 220V single-phase power unit. This modern configuration offers smooth and precise lifting while minimizing maintenance. Unlike older chain-lift systems with exposed hydraulic cylinders—which are prone to leveling issues and potential vehicle door damage—the Atlas® 412A ensures a safer, more balanced lifting experience.
In addition to the heavy-duty features found on the Atlas® 412, the 412A includes precision alignment components such as built-in slip plates and adjustable turntables. The slip plates are perfectly leveled with the turntables, allowing for accurate wheel alignment on a wide range of vehicles. The turntables can be repositioned along the runway to accommodate various wheelbase lengths, and removable steel cover plates are included to convert the lift for general service use when alignment functionality isn’t needed.
The runways are also equipped with integrated tracks designed to accept rolling bridge jacks (recommended: Atlas® RJ6BK, sold separately), providing additional versatility for wheel-off service such as brake, tire, and suspension work.
With its blend of commercial durability, advanced engineering, and multipurpose capability, the Atlas® 412A is a top-tier solution for shops seeking a professional alignment lift that can handle both heavy-duty performance and everyday service efficiency.
