What term describes the distance between the counterweight buffer striker plate and the striking surface when the car is level with the top terminal landing?

The term that accurately describes the distance between the counterweight buffer striker plate and the striking surface when the car is level with the top terminal landing is commonly known as bottom counterweight run-by. This descriptor is essential in elevator systems because it indicates the buffer clearance that is necessary to prevent the counterweight from overshooting the striking surface, ensuring that the system operates safely within its designed parameters.

In this context, the bottom counterweight run-by is critical for maintaining proper functioning and avoiding potential hazards during elevator operations. It’s important for both safety and performance, as it helps in reducing excessive force during a stop and preventing mechanical damage to both the counterweight strikers and the elevator’s structural components.

Other terms, such as minimum clearance, travel distance, and operational range, do not specifically refer to this particular measurement related to counterweights, highlighting the significance of the correct terminology in understanding elevator mechanics.
