Bulldozers earth has a lot to keep a pair divider designed to convert energy ability to drag the machine, which uses its own weight to push heavy objects and even Remove things from the earth. Take Caterpillar D9 example, you can easily remove the pressure tanks more than 70 tons. Due to these characteristics, bulldozers used for barriers, bushes, and remains of structures and buildings.

The knife Blade is a heavy piece of bulldozer metal plate placed in front. The blade pushes things. Generally, the knife comes in three variations:

1. A curved blade that is short and not We can not lateral curve, no side wings, and is used only for fine grading.
2. The universal blade, or a leaf of U, which is is too large and curved, with large wings For more material to be taken.
3. A short combination sheet, offers less curvature, and smaller wings. Changes Over time, bulldozers adapted to changing
The new machine can things bulldozers not original. A good example is that loader tractors were created by removing knife and replaced by a large number of containers and hydraulic arms up and down bucket, and are therefore suitable for the creation The land and the loads on trucks. Other changes to the original bulldozer including what is smaller where you can work in work areas where movement is very small limited, such as caves and mine tunnels. Ok known as small bulldozers calfdozers.

History

The first approach is being taken bulldozers tractors used for plowing the fields. In To dig canals, raise earth dams, and participate in earth moving work, tractors thick metal plate on the front. Later , This is a thick metal plate to win the sheet name. Peels layers of soil leaf bulldozer and pushed the tractor moves forward. The magazine is the heart and soul bulldozer, it is the first accessory to make the most The excavation for the class. As years go by, when engineers needed equipment orders, larger companies such as completion of as CAT, Komatsu, John Deere began the sentence, and JCB followed by a large earth moving equipment manufacturing. They are very strong, huge and very powerful hence the nickname “bulldozer.” Over the years, bulldozers became larger, stronger and more refined.

The most important improvements are the more efficient motors, units are more reliable, more tracks, and even hydraulic arms that allow greater precision treatment controls and automated sheet. Optionally, you can prepare subsequent extraction and claw to break the pavement or loose rocky soil.

The most famous manufacturer bulldozer CAT who have earned a reputation for producing strong and durable, reliable equipment. In order Although from agricultural practices bulldozer tractor, quickly became one of the most useful pieces of mining equipment and construction.
