The ATD Tools 3-Ton Swift Lift Hydraulic Service Jack, No. ATD-7331A, offers a quicker lift for professional performance. The dual-pump pistons are shielded to prevent contaminants from damaging the hydraulic system, and an internal by-pass valve protects the hydraulic system from over pumping. The U-joint release mechanism provides precise control of load descent, and the heavy gauge construction has rolled edges for added strength. A protective foam cover on the handle and a full-cover rubber saddle pad prevents vehicle damage while upgraded casters assist maneuverability. The service jack has a lifting range of 5-1/4" to 20" and meets the 2009 ANSI standard.
