A mobile apparatus (10) with a fluid pressure-operated implement (26) mounted at a distal end (24) of a boom (20) includes a connection apparatus (42) for selectively rotating the implement (16) about an actuator axis (44) at the distal end (24) of the boom (20). The connection apparatus (42) includes a rotary actuator (60) and a pressurized fluid circuit for delivery of pressurized fluid through the rotary actuator (60) to the implement (26). The pressurized fluid circuit includes channels (110,112) establishing a fluidic connection axially through the rotating shaft (70) of the rotary actuator (60). The pressurized fluid circuit facilitates passage of pressurized fluid through an internal, protected environment to the implement (26). |
