Ultra-Fab's engineers developed the Phoenix with ball screw technology. Instead of raising and lowering the jack with Acme threaded rods, the Phoenix incorporates a strong threaded steel rod with ball bearings. The Phoenix is rated for 4,000 pounds lifting capacity and features a stronger motor, an electronic control panel, a built in light for night operation, and an emergency crank access port with a crank socket included. In addition, it does not have external switches that might break off.
