Elevators & Escalators

by:JPSK     2020-08-19

Since the mid-19th century, elevators have played a major role in simultaneously transforming the city skylines of the world, while making daily life more convenient. Mitsubishi Electric elevators have helped contribute to the development of the high-tech cityscapes of modern society, providing architects and developers with new options for innovative building design.

Anelevator or lift is a type of vertical transport equipment that efficiently moves people or goods between floors (levels, decks) of a building, vessel or other structure. Elevators are generally powered by electric motors that either drive traction cables or counterweight systems like a hoist, or pump hydraulic fluid to raise a cylindrical piston like a jack.

Because of wheelchair access laws, elevators are often a legal requirement in new multistory buildings, especially where wheelchair ramps would be impractical.

Types of Elevators :

Passenger elevator

Freight elevator

Mine elevator

Inclined elevator

Limited-use/limited application elevator

Private residence elevator

Special purpose personnel elevator

Dumbwaiter

Material lift

Escalators:

Escalators are large, complicated and expensive installations, and the level of engineering precision and manufacturing standards required to make them work reliably day in and day out is nothing short of phenomenal. These conveyance devices are an integral part of the daily lives of millions of people around the world and are taken for granted on a mass scale.

Model development and design types

'Cleat-type' escalators :

Jesse Reno's escalators did not resemble modern escalators too closely. Passengers' feet tilted upward at an angle, and the treads consisted of cleated metal (initially) or wood (later models). Reno worked on his own for several years, gaining success with installations from Toronto to Cape Town, South Africa. Similar units of the day by other manufacturers resembled conveyor belts more than moving staircases. For a time, Otis Elevator sold Reno's escalators as their own 'cleat-type' escalators.

'Step-type' escalators :

Seeberger's model, bought by Otis, clearly became the first 'step-type' escalator, so called after its visual likeness to steps on a regular staircase. The company later combined the best aspects of both inventions (guiding slats and flat steps) and in 1921 produced an escalator similar to the type used today: they called it the 'L-type' escalator. It was succeeded by the 'M-type', the 'O-type', and current models by Otis such as the 'NCE-type' escalator.

World's Highest Class of Elevator Testing Tower

With the recent increase in the number of high-rise buildings in countries around the world, there is a growing demand for faster, larger capacity elevators. The new SOLAE testing tower contributes to the development of elevators that fulfill such demands.
