Jack device

Abstract

A jack device for lifting a heavy object, including a first arm having a base at a distal end and a second arm attached substantially perpendicular to the first arm at a proximal end, the second arm including an extendable portion actuated by an eye ring, and the first arm including a power and electronics module capable of moving the proximal end relative to the distal end. A method of using the jack device to lift or lower a heavy object, by placing the jack device near an object to be lifted or lowered, extending the extendable portion of the second arm into or under the object to engage with the object, and actuating vertical movement of the first arm, thereby lifting or lowering the object. Methods of adding and removing an interchangeable equipment sled to/from a vehicle using the jack device.
