Abstract
A lifting strut and stabilization system includes a lower outer tubular member in slidable engagement with an upper extendable inner tubular member, a mechanism for receiving and supporting a jack on the outer tubular member, a pin for optionally restraining the upper tubular member from further engagement into the lower tubular member, while allowing unrestrained extension of the upper tubular member from within the lower tubular member, and a removably attached jack having a bracket at its upper end incorporating a saddle or half-hole for engaging a strut lift pin located in a corresponding saddle, half-hole or flat bearing surface located on the upper end of the lower tubular member, the lift pin extending through the saddle holes in the upper tubular member, such that upon actuation of the jack, the upper jack bracket engages the lift pin and extends the upper tubular member from within the lower tubular member.
