Escalator and the Elevator.

Moving walkways/stairs and the Lift.

It is perhaps a strange subject to start a New Year with, but both the escalator and elevator have now been around over over 120 years. Essentially developed for the mining industry by James Borgardes in the U.S.A. He first displayed his steam model at the world trade fair in New York in 1853. E. G. Otis introduced his department store lift in 1857 and he was the first to show in Europe at the Paris exhibition in 1867.

Meanwhile it was J. W. Reno who invented the continuous moving stairs, in a new york department store in1896-97. It was the first to appear in Europe in the 1900 Paris, Exhibition. 

The Lift/Elevator made it essential in the construction of the Skyscraper and so it remains today, around the world.

Meanwhile many airports and train stations have developed moving walkways, these take the weight of carrying your cases long distances between terminals. These being a fixed machine, are still a form of transportation.

Cranes.

Free Standing and Telescopic.

We today live in a world where we think cranes are something new? But we have had a pulley crane of some description since humans needed to lift heavy weights. Those fantastic monuments of the past such as the Pyramids in Egypt, the great wall of China and the many neolithic monuments needed cranes.

Today cranes come in all sizes and formats. They are the centre of the construction of high rise buildings and also entry work to underground tunnels. Cranes in the telescopic type are used to lift heavy weight objects, from piping units to wind turbine segments to skips of materials needed at certain heights or depths. 

Some cranes work on a segmented construction basis, while others are deployed from an eight to twelve wheel truck unit.
