Abstract
A system for determining a position of a pin inserted within a pinhole of a work machine is disclosed. The system includes a follower, a sensor, and a controller. The follower is biased to be in contact with the pin to follow the pin throughout a movement of the pin within the pinhole. The sensor is configured to detect a state of the follower corresponding to the position of the pin with respect to the pinhole. The controller is configured to determine the position of the pin based on the state of the follower.
Claims20
A system for determining a position of a pin inserted within a pinhole of a work machine, the system comprising:
- a follower biased to be in contact with the pin to follow the pin throughout a movement of the pin within the pinhole;
- a sensor configured to detect a state of the follower corresponding to the position of the pin with respect to the pinhole;
- and
- a controller configured to determine the position of the pin based on the state of the follower.
A work machine, comprising:
- a frame;
- a lift arm coupled to the frame and configured to pivot relative to the frame, the lift arm defining a pinhole;
- a pin inserted within the pinhole and configured to move within the pinhole to engage the lift arm with the frame to restrict movement of the lift arm relative to the frame;
- and
- a system for determining a position of the pin inserted within the pinhole, the system including:
- a follower biased to be in contact with the pin to follow the pin throughout the movement of the pin within the pinhole;
- a sensor configured to detect a state of the follower corresponding to the position of the pin with respect to the pinhole;
- and
- a controller configured to determine the position of the pin based on the state of the follower.
