Types of bulldozers according to the movement tool

  1. Crawler bulldozer

This type of bulldozer conforms to the characteristics of heavy bulldozers, namely, with wheels equipped with tracks. This tool should be able to run in different areas. Whether in soft, muddy, hard or rocky terrain.

  1. Rad-Bulldozer

Wheel Bulldozer As the name suggests, this bulldozer has rubber wheels like vehicles in general. So this type of bulldozer does not need a carrier.

You can move this bulldozer from one place to another by driving it as usual. This is because this type of heavy equipment does not damage the road as it has rubber wheels.

Just like bulldozers, wheeled bulldozers are also used in mining areas. But for muddy areas, it seems you need to know as this tool is a bit limited.

So if you are going to use a bulldozer in a muddy area, you can use a crawler bulldozer. Aside from the types of bulldozers you need to know, it is also important that you know the types of blades on the bulldozers.

Jenis Blade Bulldozer

  • S-Blade

S-Blade stands for Straight Blade, which means straight. From the name you can tell that this type of blade is straight with no wings attached to the sides.

So this type of blade is simply straight and short. This type of blade is used to flatten a material.

And you must also know that the S-Blade is not designed for lifting or picking up materials such as sand or earth.

Because the material is not recorded or partially spills over. This is due to the lack of wings on the sides of the blade.

  • U-Klinge

The U-knife or universal knife is very large and robust. This blade has wings on the side. This shows that the U-Blade is very suitable for pushing and lifting materials.

The material picked up and lifted will not fall down due to the side wings.

  • Semi-U-Blatt

This type of blade is a combination of S-blade and U-blade. So this type of bulldozer blade is medium in size, midway between S-Blade and U-Blade, and has wings on the sides.

With this size, the half-U blade is perfect for pushing material that needs to be transported to another location far away.

  • a blade

If you use this type of blade, it will fit if you install it on a wheeled bulldozer. Angle Blade is a blade that can be tilted up to an angle of 30 degrees.

Unlike other blades that can only move in a straight position. As the name suggests, which means angle, this type of blade has the advantage of being able to tilt left or right.

So if you throw or toss aside a material, you can use this type of blade. But the downside is that this blade doesn’t have wings on the sides that will drop the material when taken with this blade.

  • Power Angle Tilt-Klinge

This bulldozer blade is arguably a blade with a complete package. Why is it called a complete package? Because the Power Angle Tilt Blade can be rotated to all angles, which means it can be tilted to all sides, not just to a straight position.

And most importantly, this type of blade has wings on the sides that allow it to pick up materials to keep them from falling.

How did you become interested in using this type of blade? These are different types of bulldozer blades that you need to know about before you buy them.


A few other tips when looking to buy or rent a bulldozer is that you also need to know what the field you are working on is like. These conditions must match the dozer blade or bulldozer to be used.
