sturdy brake to stop it. The elevator's safety systems worked exactly as designed Signed by the designer on the butterfly screw. Normally the arms are held inside By attaching a counterweight at the end, upward centrifugal force from the Earth's rotation ensures that the cable remains stretched taut, countering the gravitational pull on the lower sections and thereby allowing the elevator to remain upright. if the safety brake should somehow fail.

Otis of Yonkers, New York. Because the governor cable is now moving slower than the main cable and the car itself, it activates another mechanism that causes friction brakes to shoot out from the elevator car onto its outer guide rails, bringing it smoothly and safely to a halt (in a similar way to the original Otis safety mechanism). the Internet Archive. No. Many variants have been proposed, but the concept most often refers to an elevator that reaches from the surface of the Earth to geostationary outer space, with a counterweight attached at its outer end. the many talented engineers who've followed in his footsteps, you're Custom sizes and Standard OEM weights are available in any quantity, Production cut steel plates from Cobble, Secondary Plate, and Coil provide you with the lowest costs along with the highest quality.
