Stertil KONI two-post lifts eliminate overhead beams Stertil KONI has introduced two new two-post lifts that require no overhead crossbeams. The 16,000-lbs. SK2070 and 18,000-lbs. SK2082 lifts are fully hydraulic with no chains or cables, and include electronic synchronization with independent locking in each post. Both lifts utilize Stertil KONI's oil-impregnated nylon rollers for guide-block stability with minimum fiction, and carry a limited lifetime warranty. The SK 2070 lift is available with single or double telescopic swing arms; the SK 2082 is available with single telescopic arms. Both lifts are ALI certified.
