An auxiliary flow adjustment system and method are disclosed for controlling an auxiliary hydraulic function on a machine in accordance with commands from an operator. The auxiliary flow adjustment system includes operator controls that control a hydraulic control valve. The control valve controls flow rate and flow direction to the auxiliary hydraulic function. When the auxiliary flow adjustment system is activated, the operator can use the operator controls to select a desired flow rate and flow direction for the auxiliary function and maintain the desired flow rate and direction without further use of the operator controls. When the flow adjustment system is activated while a non-zero flow rate is selected, the desired flow rate and direction can be set to the current settings. A resume control can retrieve and command the previously stored desired flow rate and direction. Controls can be used to increase and decrease the set flow rate.

Proportional auxiliary flow adjustment system and method

An overload protection control system and method are disclosed for an articulated dump truck having a load bin movable between loaded and unloaded positions by hydraulic cylinders of a hydraulic circuit. The overload protection control system includes a source of load data associated with the load bin. The overload protection system also includes at least one controller that receives and processes the load data to determine an overload condition associated with the load bin and determines a speed associated with the work vehicle. The speed is reduced in the overload condition.

System and method for overload protection

A hydraulic system comprises a plurality of primary hydraulic circuits and a secondary hydraulic circuit for satisfying flow continuity of the primary hydraulic circuits.
