Abstract: Two embodiments (FIGS. 1 and 4) of a portable crane/winch/hoist allowing a safe flexible use with attachments to a vehicle or other designated use area while simple to assemble/disassemble with it's relatively light weight sections allows for a one person assembly and operation, is not intrusive to a vehicle's body nor is permanently attached and exposed to the elements. This device allows for a safe operation to load and unload objects while not being risky for a strain or injury when attempted by only one person in lieu of requiring two or more persons to accomplish the task. By reducing the injury risk thus limiting the potential for missed work hours and insurance claims; should result in enhanced performance production and insurance friendly rates. Additionally, this device can be adapted to shop work benches and other areas, as well as multiple vehicles particularly in the service industry i.e.; delivery, electrical, HVAC, plumbing, lawn equipment, recreational vehicles, SUV's, vans, boats/motors.

Abstract: After removal of a valve cap from an in line shut off valve the Retaining Snap Ring Adapter with male threads and seat at one end, female threads and seat at the other end, a hex outer surface at the female threaded end, a longitudinal passageway down its center, is designed to be permanently installed on an in line shut off valve having a threaded moveable plug (operator) and said Adapter will not interfere with the moveable operator which opens and closes the valve when turned by a hexagonal wrench. The Retaining Ring Adapter prevents an improperly back seated operator from being ejected as a deadly missile by the normal operating pressures.The Retaining Snap Ring Adapter having been permanently installed on the valve, the cap is returned to the valve but is now screwed onto the added Retaining Snap Ring Adapter which is essentially now part of the valve.
