Types and Uses of Bulldozers in Construction

Most construction projects need moving of a large amount of earth, soil, sand, rubble, and debris all the time, especially at the beginning of the project. For this purpose, bulldozers come in very handy in land-based construction projects. Today we will see what these powerful machines are and how they are used in the construction industry.

The phrase "bulldozer" comes from an amalgamation of the words 'bull' and 'dose'. The first word implies power, while the latter indicates a will to force something to happen. The first proper bulldozer in history was produced in 1923 by farmer James Cummings and draftsman J. E. Mcleod. But this was used for farming purposes only. Bulldozers saw construction uses by the 1940’s.

What are Bulldozers?

Bulldozers, or dozers, in short, are essentially tractors with a large blade mounted in front of them. The tractor helps push the blade around the ground. Perpendicular to the ground, the blade is a thick plate of metal, wider than the tractor behind it and sometimes even half as tall. Sometimes the dozers come equipped with a claw-like device attached in the rear called a ripper to loosen up the ground before pushing it around.

Mobility

The vehicles are generally mounted on tracks, which gives them excellent ground traction and mobility on rough unstable terrain. Some versions of bulldozers come with extra-wide "swamp tracks" to handle soft ground. Though in uneven terrain, the use of wheeled bulldozers is common too. These dozers are mounted on four articulated hydraulics-operated large rubber wheels, which gives the vehicle the ability to work on uneven terrain and also much better speed than the tracked versions.

The engines of bulldozers need to be very high-powered since they need to create a huge amount of energy to push heavy objects. Also, the same engine needs to power the often-used hydraulics system. Depending on tasks the engines of dozers can vary from 70 to 1000 horsepower.
