Abstract
The jack apparatus includes a jack having a tubular housing that is elevated by jack screw mechanism. Arm members are mounted to the tubular housing to extend transversely outwardly in opposite directions for mounting a chain to permit adjustably varying the length of chain end portions extending away from the arm members that are to be attached to the object to be elevated. A tire is mounted to the tubular housing for abutting against the object that is to be elevated, the tire extending vertically above and below the arm members, and transversely further outwardly of the tubular housing than the tire. The tire has a vertical annular surface for abutting against the object.
