Construction Vehicles.

Something we can never do without.

Every part of the building industry today relies on some form of vehicles to help. From roads to rails, from housing to skyscrapers. The Bulldozer and the JCB are probaly the most well known types, then (steam) rollers and various digger types, as well as tippers.

There is a longer history to construction of any thing, that meets the eye. Even in ancient history wheeled waggons, towers and carts, as well as cranes and pullys were employed in building. The Egyptian and Aztec Pyramids and many Celtic monuments such as Stone Henge and New Grange were constructed using slave labour and hundreds of animals to pull and heave blocks.

The future seems to be going down the road of Robotic automation and the use of more computer technologies. 

I think the idea here is perhaps saftey, but in the long term it will mean less and less human involvement and the loss of employment sadly.
