The effectiveness of this approach at high speeds, however, remains unclear, and research shows that you would likely be subjecting your knees and legs to greater injury risk at low speeds. Theoretically, your legs would flex as you and the elevator touched down, spreading your body’s deceleration over a longer period (impact force is proportional to speed and mass, and inversely proportional to time and stopping distance - the longer the time spent stopping, the less the force). More likely, you’d hit your head on the ceiling and land badly, exacerbating your injuries.Īnother suggestion holds that you should stand with your knees bent to absorb the impact, like a skydiver. Assuming you retain the presence of mind and Olympic reactions to pull this off, however, the best speed reduction you could hope for would be 2 or 3 mph. Some people advocate jumping upward a split-second prior to impact to reduce your impact speed. Life has given you proverbial lemons, and you have seconds to make some lemonade or end up as pulp. Then again, that means you’ll hit the basement doing a brisk 48 to 53 mph.

On the plus side, it’s impractical to build a hydraulic lift higher than six stories, so you’re only going to fall 60 to 90 feet.

Although they are unlikely to fail, if they do, they are more likely to fail catastrophically than traction elevators.

Hydraulic elevators, which lift and lower elevator cars using a piston jack similar to the one auto mechanics use to lift automobiles, generally lack the safety features of traction elevators (unless the builders install special aftermarket safety brakes). Each of the four to eight steel cables in a traction elevator is strong enough by itself to hold the car. Traction elevators also locate switches along the elevator shaft, which detect cars as they pass and initiate slowdowns and stops at the appropriate points in their travel, whether during a normal stop or because the car is moving too fast. If the car zips downward too quickly, the governor activates brakes on the elevator’s travel rails. Traction elevators, which move cars up and down using steel cables, pulleys and counterweights, have a speed-sensing governor. Modern elevators incorporate safety features to help prevent fatal falls.
