Abstract
A load manipulating apparatus including a turnstile 10 supported for rotation about a fixed stub shaft 30 defining a substantially vertical axis, an elevating mechanism 12 supported for vertical reciprocating motion by the turnstile, and a rotatable operating arm 14 carried by the elevating mechanism including a mechanism 205 for releasably engaging a load receiving container 18. Support columns 22 defining a path of motion for the elevating mechanism include integral fluid reservoirs that form part of a fluid pressure operating system for effecting movements in the turnstile, elevator, operating arm, and container engaging mechanism. The turnstile mounts a source of pressurized fluid 230 that communicates with a source of power through a slip ring assembly 232, enabling the turnstile to rotate through an arc of greater than 360 degrees in either direction and includes a drive motor 54 coupled to a gear 52 mounted to the stub shaft which upon actuation orbits the gear thereby effecting vertical rotation of the turnstile. The elevating mechanism includes a fluid driven motor that is coupled to gear racks mounted longitudinally along the column members.
