<p>This rotary loader and side coupling system for transfer of semitrailers or containers (20) has a vertical pivot post (28) with one or more load handling lobes or turntables (54) each mounted on a horizontal flat lobe (52) on an end of a frame or arm (36) which is hinged to a slip collar on the post and supported and propelled on wheels (60) on a concentric cam track (30, 31) to revolve thereabout and lift and lower on slopes in the cam track to transfer a load on the lobe or turntable. The turntable is fronted with a bumper or face (78) sloped or rounded or disc wheel to engage between pedestals or locators (104) or into openings on a vehicle under the load. The turntable has two depending fingers (80) spaced on opposite sides of the table"s pivot for engaging the side of a vehicle or curb to turn the table to align with the vehicle or driveway for transfer. The turntable for trailers has pedestals spaced narrow at the front for reaching under the body rails between the wheels and landing gear and spaced wide along the inner side to support the side of the trailer facing the loader for stability for transferring a semi-trailer between a railway car and a station platform car, driveway or tractor. The lobe or turntable can serve as a coupler or preferably the loader has a coupling disc wheel supported under the lobe at constant coupling height while the turntable and/or lobe are lifted or lowered. Vehicles for coupling with the loader preferably have depressed center platforms or sills between pedestals or low sides and rollers for the coupling disc and/or lobe with or without turntable to enter between. A depressed-center semitrailer is provided to couple with this loader to handle containers. A two-lobed loader is designed especially to handle railway car body sized containers. </p> |
