  • Braking system and method for machine
    Patent number: 10259434
    Abstract: Braking system includes a brake, first valve that actuates the brake based on user input, second valve configured to selectively actuate the brake, and valve actuation system including a user input device moveable between first and second positions. A brake sensor provides a signal indicative of actuation of the first valve. The valve actuation system activates the second valve if the user input device is in the first position and the first valve engaged, retaining the second valve in active state if the first valve is disengaged, deactivating the second valve if the user input device is in the second position.
    Type: Grant

  • Dump cycle counting and monitoring system
    Patent number: 7894961
    Abstract: A dump cycle counting system is provided for a work machine. The system may include a payload carrier configured to contain a payload of material and a dump actuator configured to effectuate dumping of the payload out of the payload carrier. The system may also include a controller configured to control actuation of the dump actuator and a dump control device operatively coupled to the controller. The system may further include a load counter configured to record at least one dump cycle based on a command state of at least one of the dump control device and the controller.
