Abstract

A rotor assembly for rotating and actuating a working implement, comprising a load-bearing shaft adapted to be mounted to a boom member displacing the rotor assembly. Actuation means are secured to the load-bearing shaft. A drive assembly is rotatably mounted about the load-bearing shaft and is coupled to the actuation means. The drive assembly is 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. A collector assembly is rotatably mounted to the load-bearing shaft and is adapted to receive a pressure supply therefrom. The collector assembly is provided with connector means adapted to provide the working implement with the pressure supply. The collector assembly is coupled to the drive assembly so as to rotate therewith upon actuation from the actuation means, and so as to be independent from the drive assembly to substantially avoid being subjected to loads between the working implement and the load-bearing shaft or the drive assembly.
