| Abstract: |
The invention provides a sturdy substantially rectangular scow-like turntable platform with retractable wheels for mobility and turntable mechanics for the use of heavy trucks. The turntable platform is towable and can be used with wheels down or with wheels retracted for bottom surface friction stabilization. A trailer is provided with powering devices and controls for operating the turntable motor and the various ram activated devices. The turntable motor and the rams can be powered by pressurized hydraulic fluid or by compressed air.

What is claimed is:
1. A mobile truck turntable comprising a substantially rectangular, scow-like turntable platform affixed upwardly on a top surface with carrier ramps and having drive-up loading ramps hingedly attached at both ends thereof; said turntable platform provided with mechanical means for redirecting a vehicle positioned on said carrier ramps; said turntable platform having vertical side walls and a bottom surface curved upwardly at two short walled terminal ends producing a slidable scow-like structure; said bottom surface affixed with slide plates and at least four retractable wheels positioned in wells in said bottom surface; there being mechanical means included therein for raising and lowering said wheels; there being street tires on said wheels; the arrangement of said retractable wheels with said street tires providing towable mobility for said turntable platform with two of said wheels adjacent two tow bar brackets affixed in the vertical surface of one said terminal end; said slidable scow-like structure being for sliding said turntable platform to use position with wheels retracted; there being mechanical means for raising and lowering said loading ramps; there being mechanically adjustable supports for said carrier ramps and ram activated stabilizers adjustably fitted at four corners of said turntable platform; said turntable platform having interconnected hydraulic lines as required for operating said rams turntable mechanical means; said interconnected hydraulic lines terminating at a hydraulic line junction box in a vertical side wall of said turntable platform with pressurized hydraulic fluid supplied through said junction box by hydraulic lines removably connected thereto; said hydraulic lines supplying pressurized hydraulic fluid from a trailer equipped with controls, gauges, pressure tank, pump and a gasoline or diesel engine as a power supply.
