Abstract: A loader having a vehicle frame, a load lifter, a pair of arms each having one end pivoted to the frame and the other ends pivoted to the load lifter, at least one tilt cylinder carried by the arms and having an extendable rod, first links pivoted intermediate their ends to respective arms and at their ends to the rods and to second links. The second links are pivoted to the load lifter and there is included a hydraulic system including a manual actuator for controlling the cylinder to pivot the load lifter between forward and rearward positions on the arms. The invention contemplates a hydraulic element for sensing the position of the load lifter and for halting the flow of hydraulic fluid to and from the cylinder when the load lifter is moving forwardly on the arms just short of the forward position to halt such movement and provide a hydraulic cushioning effect.

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.

Abstract: A pre-adjusted control module comprises a bracket assembly adapted for attachment to a support structure of a construction vehicle. A control lever is pivotally mounted within the bracket assembly along with a bellcrank having a roller mounted on a first arm thereof. The roller is adapted to selectively engage either one of two notches formed on a lower end of the control lever and is biased in that direction by a tension coil spring connected between the bracket assembly and a second arm of the bellcrank. A control rod is reciprocally mounted in the bracket assembly and has its first end pivotally connected to the control lever and is adapted to have its second end connected to a self-centering valve spool of a directional control valve.
