What If EVER Elevator Cable Snapped? 🛗
Description: Dusty's elevator is about to lose every cable. Twelve floors up.
Snap. He drops about a meter, and stops. A wheel at the top of the shaft, the governor, watches the car's speed; too fast, and it jams steel wedges into the rails. Elevators have used this trick since 1854. Full episode: Dusty vs. a Falling Elevator.
Overspeed governors trip the car's safety gear, which wedges against the guide rails (Science ABC). Elisha Otis demonstrated his safety brake by having the rope cut at the 1854 New York exhibition (Mental Floss). Dusty is a fictional crash-test dummy; this is a cartoon dramatisation, so please don't try it.
