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.

Abstract: A rotor assembly (14,14′) for rotating and actuating a working implement (12), comprising a load-bearing shaft (20,20′) adapted to be mounted to a boom member (11). Actuation means (21) are secured to the load-bearing shaft (20,20′). A drive assembly (25) is rotatably mounted about the load-bearing shaft (20,20′) and is coupled to the actuation means (21). And a working implement (12) so as to transmit actuation from the actuation means (21) to the working implement (12) to drive the working implement (12) about the load-bearing shaft (20,20′). A collector assembly (30,30′) is rotatably mounted to the load-bearing shaft (20,20′) and is adapted to receive a pressure supply therefrom. The collector assembly (30,30′) is provided with connector means (32A,62,76) adapted to provide the working implement (12) with the pressure supply.
