A combination of a hydraulic jack with a triangulated steel stand interlocked with a novel, key-secured, ribbed cylinder of high strength light weight alloy, thread-connected to the lifting ram of the jack. Fast finder funnels are enjoined for rapid setting and operating of the combination with a handle having a 90°bend at one extremity and a hinged center engaged by a spring released sleeve restrainer.

I claim an integrated construction whose improvement comprises a conventional hydraulic jack combined with a simple triangulated steel stand with three engaging legs that commence at a steel base plate and project upwards to reengage at a steel ring that circumscribes a conventional hydraulic jack which has a modified bearing assembly that connects by means of a U-shaped and separate key to the aforementioned steel ring, thereby allowing a load to be distributed to the stand; said modified bearing assembly is of an inverted cylinder construction whose exterior is formed in consecutively arranged support ribbing whose purpose is to engage said separate key at predetermined locations according to desired height to be maintained once said load is transferred to said stand construction; said modified inverted cylinder is attached to the bearing ram of said conventional jack by means of machined threads and screws to provide a stable continuity to the bearing ram which is maintained to be pumped up by means of a fluid retention cavity and manually applied pressures; said steel stand assembly is hence combined to form an integrated structure with the additional features of selectively applied funnels whose sole purpose are to guide a steel handle to three locations of jack or stand function as listed herein; to engage a funnel on one of the stand\s three legs so that said hydraulic jack and its contiguous stand could be moved about without entering a person or operator beneath said load, to engage the funnel that would guide said handle to the housing of the pumping mechanism standard on conventional hydraulic jacks, to engage said handle through the aid of a third and final funnel that would allow said handle to engage the fluid retention valve common to conventional hydraulic jacks.
