The classification of bulldozer models is primarily based on several factors, including engine power, undercarriage type, intended application, and specific manufacturer naming conventions. Here is a detailed explanation of how bulldozer models are categorized.

I. Classification by Power

Bulldozers are commonly classified according to their engine power, which directly determines their working capacity and suitable application range. The common categories are:

• Ultra-Light Bulldozers: Power below 30 kW.

• Light Bulldozers: Power ranging from 30 kW to 74 kW.

• Medium Bulldozers: Power ranging from 74 kW to 220 kW (or 74.5 kW to 154 kW, depending on the classification standard).

• Large Bulldozers: Power ranging from 220 kW to 520 kW (or above 154 kW, depending on the classification standard).

• Extra-Large Bulldozers: Power above 520 kW.

II. Classification by Undercarriage Type

The undercarriage type is another critical factor in classifying bulldozer models, mainly divided into:

• Crawler Bulldozers: These offer high traction, low ground pressure, and excellent gradeability, but have relatively lower travel speeds. They are ideal for complex terrain and applications requiring high pulling force.

• Wheel Bulldozers: These provide high travel speeds, exceptional mobility and flexibility, and shorter cycle times. They are easier to transport between sites. However, their traction is generally lower, making them suitable for projects requiring frequent site changes and fieldwork.

III. Classification by Application

Bulldozers can also be classified based on their intended use, primarily into general-purpose and specialized types:

• General-Purpose Bulldozers: Manufactured to standard specifications, these are suitable for a wide range of earthmoving and rock projects.

• Specialized Bulldozers: Designed for specific working conditions, such as:

• Swamp Bulldozers

• Marsh Bulldozers

• Amphibious Bulldozers

• Underwater Bulldozers

• Ship-Hold Bulldozers

• Unmanned/Autonomous Bulldozers
  These specialized models typically feature unique structures and functionalities to adapt to particular working environments and demands.

IV. Manufacturer-Specific Naming Conventions

Beyond the classifications mentioned above, bulldozer model designations are also influenced by manufacturers' specific naming systems. Different manufacturers may use unique alphanumeric codes to represent the machine's power, undercarriage type, application, and other special features based on their design philosophy and market needs.

For example, a manufacturer's model names might include prefixes like "SD," "DH," or "DE," followed by numbers indicating power output (e.g., "17," "24," "34"). Suffixes may denote special features or versions, such as "XL" (Extended Length), "RS" (Rock Specification), or other application-specific codes.

In summary, classifying bulldozer models is a detailed process involving multiple factors and dimensions. Understanding these classification methods provides a solid foundation for selecting the right bulldozer model for your specific requirements.
