Motor-driven, boom-mounted rotary coupling

A continuous rotor assembly for rotating and actuating a working implements comprising:

• a load-bearing shaft adapted to be mounted to a boom member displacing said rotor assembly;
• actuation means secured to the lead-bearing shaft;
• a drive assembly rotatably mounted about the load-bearing shaft for continuous rotation with respect to the load-bearing shaft and being coupled to the actuation means, the drive assembly adapted to be connected to a working implement so as to transmit actuation from the actuation means to the working implement to drive the working implement about the load-bearing shaft;
• and
• a collector assembly having a collector shaft rotatably mounted to the load-bearing shaft and concentrically positioned in the load-bearing shaft, the collector shaft being adapted to receive a pressure supply therefrom, the collector shaft being provided with openings at an end thereof and being adapted to provide the working implement with said pressure supply, the collector assembly being coupled to the drive assembly so as to rotate therewith upon actuation from the actuation means, while not being integral with the drive assembly to substantially avoid being subjected to loads between the working implement and at least one of the load-bearing shaft and the drive assembly.
