Moving Stairs

The moving Stair is one type of stair which keep on moving, automatically. Users are not needed to walk in these stairs, but stairs themselves keep on moving. They are also known as escalator or moving staircase or moving stairway

Moving Stairs

⇰ The moving stairs are kept moving slowly by electrically rotating the drums. It is a kind of moving bridge between two successive floors. 

⇰ Moving stairs are usually arranged in pairs, one for movement upwards and the other for movement downwards.  

⇰ Moving stairs are in very common use in Western countries, especially, at exist and entrances to underground railway stations. However, in India, accelerators are used mainly in the shopping mall, nursing home, hotels, and some privet office building.

Main Parts of The Moving Stairs

A moving stair consists mainly of three parts, they are steel trussed, framework, handrails and an endless belt with steps. Properly prepared tracks are connected to steel trusses and the steps are move on these tracks.

What is the Speed and Slope of Moving Stairs?

Its inclination with the horizontal plane should not exceed 30 degrees. Usual escalator movement speed is 45cm/sec.

Location of Moving Stair

In the case of a new structure, the moving stair needs to be located at the point, where the number of traffic is likely to be heaviest.

But for the old structure, first of all, a careful study of the flow of traffic should be made, then required to find out the suitable location(the place where the traffic flow is more) where stair should be installed.

Advantages of Moving Stairs

1. The main advantage of the moving stairs is that it can move many people at once from one place to another. A moving stair having a width of 1.20 m can carry traffic of 8000 persons per hour.  

2. It consumes less power, and no operators are required for their working.

3. Travelling on the moving stairs requires little physical effort.
