Komatsu 355 Bulldozer; For the Heaviest Construction and Mining Projects
When it comes to implementing heavy excavation, mining, road construction and moving large volumes of soil, choosing a powerful bulldozer is of great importance. Komatsu 355 Bulldozer or Komatsu D355A is one of Komatsu’s well-known models in the heavy bulldozer category, which continues to be of interest to road construction and mining machinery operators due to its high power, robust chassis and ability to work in difficult conditions.
This machine is built for projects in which pushing power, stability and continuous work ability are more important than moving speed. The combination of a powerful diesel engine, TORQFLOW transmission system, tracked chassis and large blade makes the Komatsu D355A a serious option for moving large volumes of materials in each work cycle. Kavir Machine Espadana is one of the reputable importers and sellers of Komatsu bulldozers and other leading imported brands in Iran.

What is the power of the Komatsu 355 engine?
One of the main strengths of the D355A is its large and powerful engine. In some versions of this bulldozer, the SA6D155-4A engine with a gross power of about 410 horsepower at 2000 rpm has been introduced. The engine volume is also reported to be about 19.26 liters.
This combination is designed for work where the machine must transfer a lot of force to the ground for a long time. For this reason, the Komatsu 355 is more suitable for heavy projects and should not be compared to medium bulldozers in terms of working capacity.
TORQFLOW power transmission system
The power transmission system is one of the important parts of the bulldozer’s performance. The D355A is introduced in some technical specifications with the TORQFLOW system and four forward and four reverse gears. The final speed of these versions is also announced to be about 12.7 km/h.
In bulldozing operations, the main goal is not to achieve high speed; rather, the machine must be able to generate adequate traction when pushing large volumes of soil or materials. The power transmission system of this machine is also designed with the same approach.
Komatsu 355 Bulldozer Blade
The blade is one of the most important parts that directly affects the productivity of the machine. The Komatsu D355A can be used with different blades depending on the version and type of equipment.
For example, in one of the published specifications for the D355A-1, the blade width is about 4.315 meters, its height is about 1.875 meters and the blade capacity is about 15.2 cubic meters.
In some versions, a U-blade or different equipment is provided, which causes a significant difference in the capacity and dimensions of the machine. Therefore, if the purpose of purchasing a Komatsu 355 is for a specific project, the blade type should be examined along with the engine and chassis specifications.
What projects is the Komatsu 355 suitable for?
Due to its large size and power, the D355A bulldozer is not considered an economical choice for light work. This machine shows its true value when the volume of operations is high.
Its most important applications include:
Heavy mining operations
Open pit mine development and development
Large road construction projects
Large volume earthmoving
Large land preparation
Clearing and leveling project routes
Working in difficult terrain
Large construction and infrastructure projects
Heavy ripper operations
Some sources have also introduced the D355A specifically for mining operations, extraction and large earthmoving projects.
What is the use of the Komatsu 355 ripper?
In projects where there is very dense soil, frozen soil, or hard layers, using a ripper can be very important.
The ripper first loosens the hard ground to prepare the material for movement. As a result, the combination of a powerful bulldozer + the right ripper can increase the efficiency of the operation.
Of course, the presence or type of ripper affects the weight, dimensions, and performance of the machine; Therefore, when buying a second-hand Komatsu 355 bulldozer, you should check what type of ripper the machine comes with and what its condition is.
Why is it economical to buy a Komatsu 355 bulldozer?
The initial price is only one of the criteria for purchasing heavy machinery. For a contractor, more important than the purchase price is the amount of work that the machine can do during its lifetime.
Due to its heavy structure and high engine power, the Komatsu 355 bulldozer can be a good choice for projects that require continuous pushing and moving large volumes of soil.
On the other hand, many machines on the market are sold as used. Therefore, the actual condition of the machine is much more important than its appearance.
A D355A with a healthy engine, a suitable power transmission system and a low-wear chassis can be worth much more than a machine that simply has a cleaner appearance.

What should we pay attention to when buying a second-hand Komatsu 355 bulldozer?
If you are planning to buy a used Komatsu 355 Bulldozer, it is better to have the machine inspected by a heavy machinery expert before paying.
-
Engine
Check the engine both hot and cold. Unusual smoke, irregular noise, oil leaks, oil pressure, and the condition of the cooling system are some of the things to look out for.
-
Drivetrain
Check the operation of the gears, forward and reverse movement, and the response of the machine under load. Repairs to the drivetrain on a heavy bulldozer can be quite expensive.
-
Undercarriage and Track
Carefully inspect the chain, shoes, rollers, sprockets, and other undercarriage components. Wear and tear on these parts can directly affect the final purchase price.
-
Blade
The cutting edge, hydraulic cylinders, pins and bushings, and the structural integrity of the blade should be checked.
-
Ripper
If there is a ripper, check the health of the teeth, arms, pins, bushings, and hydraulic jacks.
- Serial number and history of the machine
The serial number, year of manufacture, repair history, and operating history of the machine can provide the buyer with valuable information about its true value.

What factors does the price of the Komatsu 355 bulldozer depend on?
Year of manufacture, exact model, hours of operation, engine condition, transmission and TORQFLOW health, undercarriage condition, blade type, presence of ripper, hydraulic condition, amount of repairs performed, and the appearance of the machine.
For this reason, comparing two machines based solely on the D355A model can be misleading.
Advantages of the Komatsu D355A bulldozer
The most important strengths of this model can be summarized in a few points:
Powerful engine for heavy operations
Heavy weight and suitable stability
Tracked chassis suitable for working in difficult terrain
High blade capacity in some configurations
Ability to be used in large mining and construction projects
Ability to be equipped with a ripper
Suitable structure for continuous and heavy work
Summary; Is the Komatsu 355 worth buying?
If your project requires a heavy-duty bulldozer for moving large volumes of soil, mining operations, or large construction projects, the Komatsu 355 bulldozer can still be an option to consider.
The engine power, high weight, TORQFLOW transmission system, and the ability to use various blades and rippers make this model a suitable machine for heavy-duty work.
However, when buying a used model, you should not only base your decision on the Komatsu name or the D355A model. The health of the engine, transmission, hydraulics, undercarriage, blade, and ripper should be professionally checked before making a deal.
If your goal is to buy or sell a Komatsu 355 bulldozer, check the exact specifications of the model, year of manufacture, operating hours, and technical condition of the machine so that its price and real value can be more accurately assessed.
