Dozers, Special vehicles and Equipments

Here we have explained the most relevant topics as per your syllabus, previous year questions papers and our personal experiences. Every topic is defined in the easiest and most affordable way that can be made accessible to everyone.

* Dozers:

Bulldozers are strong and sturdy machines that mainly assists with pushing, digging, excavating, and leveling materials such as soil and debris at a work site. They come with large, heavy blades in the front side that push material. Some come with other modifications like rippers in the rear to help break down tough ground.

Three Main Types Bulldozer Types

There are many different bulldozer types to choose from depending on your specific project. The type of terrain you’re working on, your project type, and other criteria are key factors to consider when selecting a bulldozer. The right machine is also crucial for both the efficiency and safety of your project.

Crawler Bulldozer

A crawler is sometimes referred to as a track bulldozer and looks most similar to a tractor. This heavyweight is great for moving heavy materials from one area to another. This bulldozer is ideal for traversing dense and irregular terrain since the tracks give it great traction. Larger crawlers have rippers that assist with crushing and clearing dense terrain.

Wheel Bulldozer

Sometimes this machine is also referred to as a tire bulldozer and is normally larger than a crawler. A wheel dozer is more maneuverable than a crawler since its tires offer better overall handling. It also has completely articulated hydraulic steering and moves on a smaller axis. This machine is also ideal to use for soft or sensitive ground since the tires are gentler than tracks.

Mini Bulldozer


This smaller bulldozer is also known as a compact bulldozer. A mini dozer is great for projects that require more maneuverability and versatility than larger machinery. Thanks to its small size, a compact bulldozer can perform well in different types of projects that require tasks like grading and clearing lots.

* Track Chain

Dozer rails, or also known as continuous or caterpillar tracks, are some sort of plates or pads that are linked and pivoted together to form an endless chain wrapped around a series of wheels on a bulldozer. Bulldozers are machines that are formally known as track-type or track-laying type tractors, they have one dozer rail on each side respectively.

* Sprocket:

Sprockets are circular rings that are used to support the track chains.
