1830 In the years around 1830 Faraday developed the first electromagnetic generator of electric current (dynamo and alternator). Joseph Henry perfects a particularly powerful electromagnet thus allowing the transmission of electrical energy over great distances.

2019年8月11日 · Primitive elevators were in use as early as the third century B.C.E. and were operated by human, animal, or water wheel power. In 1743, a counter-weighted, man-powered personal elevator was built for King Louis XV, connecting his apartment in Versailles with that of his mistress, Madame de Châteauroux, whose quarters were one floor above his own.

The invention of the elevator during the 19th century is attributed to Elisha Otis. In 1852, Otis introduced a safety device known as the “safety brake” or “safety hoist,” which prevented the elevator from falling if the lifting ropes broke.

By 1800, steam power was used to power such lift devices, and in 1830, several European factories were operating with hydraulic elevators that were pushed up and down by a plunger that worked in and out of a cylinder.

2021年7月6日 · Modern elevators, similar to those we’re familiar with today, were first invented in the 1800s. Elevator design began to transition to carrying people instead of just goods in the 1850s, and in 1852 the first elevator safety devices were invented.
