Bulldozers, or dozers, are heavy equipment used to move materials or for demolition, deforestation or leveling works. A bulldozer may be equipped with a scraper pushed by the machine.
Dozers are tractors, generally mounted on tracks and equipped with a large front blade called bull blade, which may be orientated vertically. It may be lowered to scrape the ground at a depth of 30 centimeters, or lifted to carry materials. Different types of bull blades can be found: the straight blade (S-blade), the universal blade (U-blade), the semi-universal blade (S-U blade), or the Power Angle Tilt (PAT) blade. Bulldozers equipped with a PAT blade are called angledozers because their blade may be orientated horizontally. Most of dozers are equipped with a ripper at the rear to work the ground. A ripper may be single (and then called giant ripper) or in group of two or more (multi shank rippers).
After being invented in the USA, bulldozers were imported in Europe at the end of WW2 to help rebuilding the continent. Some armored models had then been used on the D-Day landing beaches.
