The Sunex 6614 Air Hydraulic Floor Jack has a 10 ton capacity with a lifting range of 6.25” to 22.5”. It can be operated by manual pumping or by depressing an air valve. It is designed with a hydraulic power unit, 3 position handle lock, wiper seals, a rear kick plate, heavy gauge steel side plate, and bypass and overload valves. The ram and pump piston is flash-chromed to prohibit rust. The caster wheels allow for easy maneuverability. We put all of our lifting equipment through a voluntary and rigorous safety certification process, as outlined by the ASME PASE-2014 Safety Standard for Portable Automotive Service Equipment.
