ABSTRACT:
A positioning system for controlling the rotation of a shaft or other member through a defined angular increment. The system includes a rotor which may be coupled in torque transmitting communication with the shaft, and a an indexing assembly for driving the rotor. The indexing assembly includes a slide or other follower which is operably coupled to a first actuator, which may be hydraulically or other otherwise fluid-powered, and to a biasing member, which may be a second actuator, which is also operably coupled to the first actuator. The first actuator is actuable to move the follower and, in turn, a pawl from a locking position to a release position, and to engage another pawl with the rotor effecting the rotation thereof in a rotary direction through the angular increment. The first actuator is de-actuable to return, responsive to the biasing member, the pawls and follower to their original positions.
