or any other structure. The first elevator-like structure was built in 236 BC by the

Archimeds. This construction was a hoist operated by ropes and pulleys. However, the

first pragmatic elevator was not developed until the 19th century. Though sensible, this

elevator has been modified many times throughout the course of history and is still

updated with all of the new advancements in math and technology. From the start of the

production of elevators through today, there have been numerous and boundless

improvements made on their structure and how they operate: all due to the advancement

The first elevator developed was known as a manual elevator. This system of

elevators used "relay logic". Relay logic was a simple wiring based on circuits. This type

of elevator did not transfer people from one level to another, only cargo.

The second type of elevators was developed in the 1800s. These elevators were

powered by steam. At first, these elevators were used solely to transport freight in

factories and ore in mines. Unfortunately, these elevators required a safety device to

progression, along with that of the push-button controls were key introductory elements

controlling the elevator's destination was applied. This system was called automatic car

application in 1889. This presentation took place in one of New York's finest buildings,

In 1915, eleven years after the push-button controls, the first automatic system of

Time-Life building (1971). By this time, elevators had vastly ameliorated, but

Operated by means of a vertical plunger, this elevator traveled up and down a cylinder

if both sets of doors are shut. In nearly all buildings, elevators contain photoelectric

pressure exerted upon a liquid is transmitted in all directions at the same magnitude. This
