  • Excavator control for load delivery
    Patent number: 11180904
    Abstract: An engine on an excavator provides power to a hydraulic pump that pumps hydraulic fluid under pressure to a hydraulic actuator. The hydraulic actuator is controlled to place a load on the engine. Engine response to the load placed on it by the hydraulic actuator is detected and logged. The logged engine response data can be accessed to identify engine response.
    Type: Grant

  • HYDRAULIC MANAGEMENT SYSTEM AND METHOD BASED ON AUXILIARY WORK TOOL USAGE
    Publication number: 20140150304
    Abstract: A hydraulic management system and method are provided that account for auxiliary work tool usage. The hydraulic management system automatically calculates an effective use time of a hydraulic element, such as a hydraulic fluid or hydraulic filters, by multiplying work tool usage by a desired gain factor, where the gain factor may exceed 1 for auxiliary work tools.

  • Pattern select valve for control levers of a title work vehicle
    Patent number: 7036248
    Abstract: A backhoe control pattern selection arrangement is provided for a backhoe controlled by two control levers. The two levers are operatively connected to hydraulic systems that operate the boom and crowd hydraulic cylinders. An electrically operated valve block is electrically connected to a source of power and to a control switch, and hydraulically connected to the hydraulic systems. Changing the state of the control switch actuates the valve block and modifies the hydraulic systems to reverse the correspondence between the control levers and the boom and crowd functions.
