Maximum travel distance of 4,250 mm (168 in.) corresponds to which term?

Explanation:
The distance described is the travel limit—the maximum stroke the escalator’s moving parts can travel from end to end. This defines the end stops of the drive and ensures the steps don’t overrun the top or bottom. So 4,250 mm (168 in) is the travel limit. The other terms refer to different things: the runway enclosure is the protective housing around the escalator structure, the safety switch is an emergency or safety stop device, and the mechanical lock is a device used to secure components for maintenance. None describe the distance the escalator can travel, which is why the travel limit is the correct term.
