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;
- a lift arm coupled to the frame and movable relative to the frame;
- and
- an actuated pin assembly actuatable between a stowed configuration and a locking configuration, the actuated pin assembly comprising:
- a stationary member;
- a movable member coupled to and movable relative to the stationary member;
- and
- a pin body coupled to the movable member and movable with the movable member relative to the stationary member, the pin body including (i) an interior surface at least partially defining an axial bore that, with the actuated pin assembly in the stowed configuration, surrounds at least a portion of the stationary member and (ii) an exterior surface that, with the actuated pin assembly in the locking configuration, contacts at least one of the lift arm or the frame to inhibit movement of the lift arm relative to the frame.

An actuated pin assembly comprising:
- an actuator comprising a movable member and a fixed member, the movable member being movable relative to the fixed member between a retracted position and an extended position;
- and
- a pin body coupled to the movable member to move with the movable member relative to the fixed member, the pin body including an interior surface at least partially defining an axial bore that, with the actuator in the retracted position, at least partially surrounds the fixed member of the actuator.
