The Atlas Platinum PVL14OF-EXT is a four post commercial grade Open-Front Alignment lift designed with the professional shop in mind. This lift has extra long runways and can accommodate a variety of cars, vans, SUVs, trucks, and commercial vehicles. the Open-Front design allows better access to the underside of vehicles during use. The AP-PVL14OF-EXT features built in slip plates and a pair of heavy duty turntables so the user can do wheel alignments. The Platinum PVL14OF-EXT uses a high strength cable system (with a under runway oversized hydraulic cylinder) powered by a 220 volt (single phase) power unit to raise and lower the lift. Many competitors use an "old style" chain lifting system with an exposed hydraulic cylinder system. Old style chain lifts are difficult to "level" properly and the exposed hydraulic cylinder is responsible for numerous "door dings". The Atlas Platinum PVL14OF-EXT features "tracks" between the runways to allow the use of a rolling bridge jack (recommended is the Atlas Platinum RJ7000 ) on the lift. Rolling jacks sold separately. The Atlas Platinum PVL14OF-EXT is also ALI certified and backed by one of the industry's best warranties for an added peace of mind. This product features an ALLY Hydraulic AL3000 Power Unit. This premium power unit is certified by MET Laboratories Inc. for electrical compliance in the United States and Canada. Extra heavy-duty armatures and more motor windings with increased silver metal included in the wires and connections create far less heat generation and allow ALLY Hydraulic power units to maintain constant torque through the lifting process. This power unit also carries an industry leading two-year limited warranty.
