Abstract: Typical loading machines utilize a pair of lift arms to mount a work implement to a machine frame. The spacing of the lift arms and the tilt linkage mounted to the lift arms to manipulate the work implement reduce the visibility to the work implement as well as increase the overall weight of the structure. The present invention provides a boom-type lift arm that has a non-clevised configuration on both end portions thereof that mount a work implement to the frame of a machine. The tilt linkage is mounted between the lift arm and the work implement to rotate the work implement with respect to the lift arm. The work implement defines a pair of mounting plates that mount both the tilt linkage as well as the lift arm.

Abstract: A valve group subassembly for use in a vehicle having hydraulically operable mechanisms. The subassembly includes the main valve and actuators, interconnecting duct structures, and a mounting bracket permitting the complete subassembly of the control elements. A pilot valve manifold is mounted to the bracket for hydraulic connection thereto of the pilot valves. The bracket may be resiliently mounted. The valves may be provided with removable valve stems, permitting the valve bodies to be maintained mounted to the bracket in servicing the individual valves. The subassembly is arranged to permit a bench testing thereof prior to the installation in the vehicle.
