Crawler Dozer

Crawler Dozer

A crawler bulldozer is a heavy plant machine used primarily for pushing and moving large amounts of earth, rubble and other heavy materials. This type of machine does not have traditional tractor tires but instead has a continuous metal roll (or track) which enables it to move over a range of surfaces. At the front of the crawler bulldozer is a large, horizontal, sheet of metal which is positioned and shaped for effectively pushing materials around the site.

A crawler bulldozer is perfectly designed for its main function due to the sheer power it is able to generate and the excellent levels of traction achieved through the continuous metal tracks. The tracks also help to evenly distribute the significant machine weight across the surface; this can be useful when working on less dense and secure sites.

In addition to the front blade, most bulldozers also have a further device attached to the rear which is called the ripper. The ripper consists of one or more blades which are used to break up concrete and other materials.

The dominant manufacturer of these bulldozers is Caterpillar in the USA but there are a number of other important brands which include John Deere, Komatsu, Liebherr and others.

Bulldozers are used on industrial sites all over the world which generates global demand for the machines along with the engineers qualified to maintain and repair them.
