A bulldozer is a construction machine of a caterpillar or wheel drive, with a massive, metal plate (shield) installed outside the running base of the machine, called a blade. The bulldozer is used to move large amounts of soil, sand, gravel, or other material on a plane during construction work or work to transform and re-landscape.
This special equipment is used in various fields: in mines and quarries, in the construction of military installations, in the heavy and forestry industries, in agriculture.
Most often, bulldozers are large and strong tracked vehicles that can do heavy work in completely off-road conditions. The track allows the weight of the bulldozer to be distributed over a larger area, which provides less pressure on the ground and thereby prevents it from sinking into sandy or muddy soil.
That is why crawler bulldozers are often used in road construction, mining, forestry, land clearing, utility construction, as well as in any other work that requires high traffic and the use of powerful earthmoving equipment.
Wheel dozers are powered by a 4-wheel drive and a hydraulic, articulated steering system. They have less traffic, but are fast and maneuverable construction equipment capable of performing earthmoving work.
