  • Control system for actuated pins
    Patent number: 12325972
    Abstract: An actuated shear pin includes an actuator and pin body coupled to the actuator. The actuator selectively configures the pin body in a locking configuration or a stowed configuration. In the locking configuration, the pin body is placed in a travel path of two components configured to move relative to each other, to inhibit such relative movement. In the stowed configuration, the pin body is out of the travel path, thereby allowing the two components to move relative to each other.
    Type: Grant
    Filed: April 4, 2022
    Date of Patent: June 10, 2025
    Assignee: Caterpillar Inc.
    Inventors: Riley A. Albers, Jason P. Wigg, Dennis W. Dicker, Rowan T. Franks, Robert A. Herold, Steven R. Krause, Fuaad A. Sayeed, Brodie L. Thompson

  • Hydraulic system having dual tilt blade control
    Patent number: 8893818
    Abstract: A hydraulic system for a machine is disclosed. The hydraulic system may have a tank configured to hold a supply of fluid, a pump configured to draw fluid from the tank and pressurize the fluid, a first cylinder operatively connected between a first side of a work tool and an undercarriage of the machine, and a second cylinder operatively connected between a second side of the work tool and the undercarriage of the machine. The hydraulic system may also have a first electro-hydraulic valve associated with the first cylinder and configured to selectively regulate a flow of pressurized fluid to the first cylinder independently of the second cylinder, and a second electro-hydraulic valve associated with the second cylinder and configured to selectively regulate a flow of pressurized fluid to the second cylinder independently of the first cylinder.
