WIPO Patent Application WO2004104304
Kind Code:

Abstract:
A lift arm assembly (28) for a loader (10) comprises a pair of lift arm links (32,40) that are pivotally mounted together (42) at first ends of the links (32,40). A first lift arm link (32) is of substantial length and is pivotally mounted (34) to the frame (12) of the loader adjacent the rear lower portion of the frame (12) and extends upwardly. A second lift arm link (40) extends forwardly from the first lift arm link pivot (42) to a position ahead of the loader frame (12). A control link (68) has one end pivotally mounted adjacent a forward end of the loader frame (12), and a second end pivotally mounted to the second lift arm link (40) to guide the second lift arm link (40) as it is raised. An extendable and retractable actuator (62) is pivotally between the first lift arm link (32) and the second lift arm link (40). The control link (68) guides an outer end (56) of the second lift arm link (40) in a substantially vertical path as the actuator (62) is extended and retracted.
