Abstract
A leveling and stabilizing jack includes an intermediate member joining first and second lifting sections. Each lifting section includes a cross beam, a leg, a brace, a foot, a motor and a drive screw. The motor powers the drive screw, which is operably associated with the leg, to cause the leg to extend away from or retract toward the cross beam depending on the motor's direction of rotation. A motor control can control the motor of each of the lifting sections independently in a manner that results in leveling of the jack when deployed.
