What component is automatically released by a cam on the elevator car when the car is within a few inches of floor level?

Explanation:
As the elevator car approaches the floor, a cam on the car mechanically trips the hoistway door lock. Releasing this lock at close range allows the door interlock to function properly and the hoistway door to be opened safely. This design ensures doors only open when the car is near and properly aligned with the floor, maintaining safety for passengers. So, the hoistway door lock is automatically released.
