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.
Claims20
A machine comprising:
- a frame;
- one or more lift arms coupled to the frame and movable relative to the frame;
- a sensor;
- an actuated pin assembly comprising a locking pin actuatable between a stowed configuration and a locking configuration;
- and
- a controller configured to perform actions comprising:
- with the actuated pin assembly in the stowed configuration, receiving a signal to lock the one or more lift arms relative to the frame,
- receiving sensor data from the sensor,
- determining, based on the sensor data, a position of the one or more lift arms relative to the frame, and
- based at least in part on the position corresponding to a locking position of the one or more lift arms, actuating the locking pin from the stowed configuration to the locking configuration.
A method of locking out an implement on a machine, the method comprising:
- receiving a signal to lock the implement relative to the machine;
- receiving sensor data from a sensor on the machine,
- determining, based on the sensor data, a position of the implement relative to the machine;
- and
- based at least in part on the position corresponding to a locking position of the implement, actuating a locking pin from a stowed configuration to a locking configuration.
A machine comprising:
- a frame;
- an implement coupled to the frame and movable relative to the frame;
- an actuated pin assembly comprising a locking pin actuatable between a stowed configuration and a locking configuration;
- and
- a controller configured to perform actions comprising:
- with the actuated pin assembly in the stowed configuration, receiving a signal to lock the one or more lift arms relative to the frame,
- determining a position of the implement relative to the frame,
- based at least in part on the position corresponding to a locking position of the implement, generating a signal to actuate the locking pin from the stowed configuration to the locking configuration, and
- actuating the locking pin from the stowed configuration to the locking configuration based at least in part on the signal.
