The fuel consumption of the Komatsu D65E-12 model is 180 g / kWh, and the fuel tank holds up to 406 liters.

Engine

Komatsu D65E-12 is equipped with a 4-stroke diesel engine model 6D125E with liquid cooling, direct injection, standardized exhaust gas composition and natural suction. The engine power is 190 (159) hp. (kW), speed - 1800 rpm. Among the analogues, the D65E-12 is considered the most economical bulldozer.

The power of the unit is fed to the final drives through a torque converter. This process is highly efficient. The 6D125E meets the latest global environmental requirements, despite its high power and performance. The access to the check of the engine and its components is facilitated thanks to the side doors, which are opened by the action of a gas spring cylinder.

Device

The track carrier frame, swing axles, and flat bottom frame give the Komatsu D65E-12 excellent maneuverability in sticky and wet terrain and prevent dirt from sticking to the frame.
The modular design of the power train allows units to be installed or removed at maximum speed. Multi-disc brakes, operating in oil, extend service life by eliminating the need for maintenance during operation and adjusting the brake band. Thanks to the straight body frame made of thicker plate, Komatsu has been able to reduce the number of component parts, which has a positive effect on the model's reliability. For maximum durability, the manufacturer has reinforced the box blade back beam and increased the track frame cross section.

Almost all Komatsu bulldozers (including the D65E-12) are equipped with a Torkflow hydromechanical transmission. It provides smooth gear shifting under load. You can change the direction of movement or change gear using the multifunction joystick. He is also responsible for controlling the turn of the bulldozer. The planetary gear-hydraulic motor and brake-clutch function allow the machine to move smoothly, even when cornering. If the operator needs to change the route, he moves the joystick to the left or forward. The driver uses the wrist to change gears.

You can select Power (P) or Economy (E) mode. In the second case, at the output you get power, which is enough to carry out specific work. In particular, this is relevant when performing work with movement down the slope, leveling operations, etc. Switching between modes is performed on the control panel.

Engine

The Komatsu D65EX-16 bulldozer is equipped with an electronically controlled SAA6D114E-3 engine, which is the company's own development. The powertrain design includes a turbocharger, direct fuel injection and charge air cooling. The installation of the diesel engine on the main frame is made with the use of rubber cushions, thereby the developers have achieved a reduction in the level of noise and vibration. The radiator fan speed is electrically controlled.

Cab and controls

The control system is also the development of Komatsu specialists, it is called PCCS. There are separate joysticks to control the blade / ripper (hydraulically driven) and move the machine. The operator is required to make a minimum of effort.

For the Komatsu D65EX-16 bulldozer, two gear shift modes are available: automatic and manual. The use of the former is recommended by the manufacturer for standard work. In this case, the inclusion of a lower gear when the load increases and the transition to a higher gear when there is no load occurs automatically, which helps to save time with repetitive operations. In manual mode, the lower gear is also engaged automatically, but when the load drops, operator intervention is required.

Komatsu d65 bulldozer at work

General technical characteristics of the bulldozer Komatsu D65E 12:

How a car motor works

Not the least important for the car is the installation of the propulsion system, on which a 6-cylinder four-stroke engine is installed, which belongs to the serial class SAA6D114E-3. For this group of engines, direct fuel injection is provided, which is provided by an additional direct cooling system. According to the main technical characteristics, the Komatsu D65EX 16 bulldozer consumes 180 g / kWh of fuel. The power unit complex has the following parameters for the controls of the Komatsu D65 bulldozer:

Features of working comfort for the driver

The cab of the machine has a reinforced version, which provides additional protection options for the operator of special equipment. The cabin interior is equipped with additional protection systems to prevent moisture and dust ingress. Additionally, protective screens are installed that reduce the noise level inside the cab, thus the operator practically does not feel the operation of the motors, which negatively affect the hearing.

For comfortable control, a joystick is installed inside the cab, and a special technological operator's workplace is also equipped. Convenient control in hot and cold seasons is provided by air conditioners, heating and ventilation systems, which have an innovative solution. Better visibility and visibility is ensured through the implementation of panoramic glazing inside the car.

General device and design

As the main frame for the bulldozer, a suspended frame made of special durable steel grades is used. For the frame used in the tracked vehicle, special metal structural elements and blanks with a dimensional cross-section are used. The undercarriage of the machine is equipped with a special tracked link of increased strength, which has self-lubricating characteristics, where up to 39 belt links with increased overall dimensions are provided. This factor allows the bulldozer to move comfortably and without problems on land plots that have a difficult geographic relief.

For the supports that are used in driving wheels, an automatic adjustment is provided, which ultimately guarantees a long service life of specialized equipment in various conditions of the machine's use. In addition, the supports reduce such negative factors as noise and vibration.

Positive and negative aspects of special equipment

Like any type of transport, the Japanese manufacturer's bulldozers have their negative and positive sides. So, the plus are:

All parts and components of the machine have high technical parameters from a direct manufacturer.
High power parameters compared to the same class of machines.
Fuel consumption is one of the lowest.
Excellent maneuverability, even in confined working conditions.
Simplicity and ease of operation and maintenance.
The special equipment meets the highest international requirements for environmental operation.

There are practically no drawbacks, but it is expressed only in the high cost of the car. If you are renting a car, the Japanese brand's bulldozer does an excellent job, while its cost pays for itself up to 100% in a record short period of time. An additional disadvantage is maintenance, which requires the use of expensive spare parts and lubricants. Otherwise, the Komatsu D 65 bulldozer has only positive aspects of performance.

Machine modifications

For all the time, the Japanese manufacturer did not make any modifications to the car, as he believed that this line could not have additional modification series. Along with this, the manufacturer introduced some variations of the current model:

Komatsu D65 E Series
Komatsu D65 EX Series. This series allows the use of a rotary blade. In general terms, the car does not differ from the basic model.
Komatsu D65 A series. In this range, the blade can be adjusted according to the main parameters of the machine.

Summing up, it can be noted that the variations of special equipment differ only in the operational part of the blade, which is used for specific technological work.

Conclusion

As mentioned above, one of the disadvantages of a bulldozer is its price. In Russia, they know that the very high cost of special equipment completely covers all the costs associated with earthmoving work. According to statistics, Komatsu D 65 least of all requires maintenance and repairs, so the demand for a car remains quite high not only in Russia, but also in countries of far and near abroad. The manufacturer makes technical changes to the controls almost every year, equipping them with electronics and other "smart" fillings that allow the bulldozer operator to easily manage the most sophisticated special equipment of our time.

History of creation

Komatsu is a well-known global brand of tractor equipment manufacturer. In fact, the company was founded in 1921 and was engaged in the repair of construction equipment. Most of the team that founded the company has been trained in Europe and the United States of America. By the beginning of the 30s, the company began producing the first prototypes of tracked vehicles.

The history of the construction of Komatsu bulldozer equipment began in the post-war period. In 1947, the D50 was the first bulldozer produced. It was with this class of technology that the inhabitants of the Far East and the northern regions of the Soviet Union got to know in Soviet times. The equipment of this manufacturer was actively purchased in the early 60s, before the appearance of similar equipment of domestic production.

Later, special-purpose equipment was purchased, for example, class 4 bulldozers, which had just begun to be designed in domestic design bureaus, pipelayers, forestry equipment, loaders, mining units, presses and much more. Komatsu equipment was actively used in the construction of the BAM, in the development of minerals in Yakutia and Siberia. It has found application in our days, being considered one of the world's best manufacturers.

The only representative of Komatsu in the post-Soviet space is the subsidiary of this corporation "CIS Komatsu" with headquarters in Moscow. The firm confirmed its interest in the Russian market in 2010 by opening a Komatsu Manufacturing Rus plant in Yaroslavl.

The Komatsu Heavy Bulldozer with Ripper is effective in loosening and moving soil. Its qualities are most widely disclosed in the mining industry and at processing plants.

Design features

Constant improvement by the team of designers of units and assemblies of manufactured equipment is the reason for such popularity of the Komatsu D65 bulldozers. Among the latest improvements that increase its reliability and comfort, we note:

Undercarriage for stability of the machine when working on sloping ground. Achieved by reducing the location of the drive and installing wider tracks of increased length;
Fan, cooling the engine radiator with a unique hydrostatic switching drive, working in automatic mode. Rapid adjustment of the coolant temperature, saves fuel and extends the service life of the power unit. Has a reversing mode used to clean the radiator from dirt;
The control amplification system of the Komatsu 65 bulldozer is based on the use of hydrostatics. Allows you to apply the same force to the steering wheel to turn and control the machine on soils of different densities and in different operating conditions;
Completion with new dumps that exceed the volume of dumps of previous generations.

Operator's cab

In a sealed, with a double noise-insulating layer, the operator's cab provides conditions for safe and full-fledged work. Air filters are installed. A separate compressor blows air into the cabin, creating an excess pressure in it to block the penetration of dust from the outside. The Komatsu bulldozer cab is installed on damping supports, which with great efficiency smooth out the inevitable vibration and shock loads. The hexagonal shape allows you to observe the working process without distorting objects arising from observation through the glass of a conventional quadrangular cab. Other interesting aspects of the cockpit, which received the project name "Space Cab ™", are:

High performance air conditioner;
A control system in which the functions of changing the movement and control of the blade are implemented by one lever, such as a joystick;
For the operator's convenience, the chairs have height-adjustable armrests;
Heated glasses.

Power unit

The engine installed on the Komatsu D65 bulldozer uses a microprocessor-based control system for complete fuel burnout in the combustion chamber. The presence of an on-board system that monitors the optimization of the processes of ignition and combustion of fuel made it possible to increase the power output. Reduce the consumption of diesel fuel and the release of solid particles into the atmosphere. The engine is marked SAA6D114E-3. It is a turbocharged diesel. Develops a power of 210 hp. Working volume 8250 cm³. Single row design with six combustion chambers. The piston stroke is 135 mm. Diameter 114 mm.

The Komatsu TORQFLOW transmission fitted to the Komatsu 65 dozer is equipped with a locking lever and a switch to prevent the machine from rolling away accidentally when left on uneven ground. Three gears provide six speeds: three forward and three reverse.

Chassis

Lowering the center of the drive on the Komatsu D65E, combined with the use of increased link heights on the tracks, improves ride performance. Another positive aspect that makes work easier is the ability to fully see the blade knife for the operator. Much attention has been paid to the fight against vibration. Vibration characteristics are reduced due to:

two upper rollers installed on each side and preventing the tracks from jumping in the vertical direction when driving;
Seven double-sided road rollers keep the chassis in an optimal position, reducing wear.

The Komatsu D65E bulldozers are equipped with self-lubricating tracks with a standard length and height of 65 mm lugs with a total support area of 32,940 cm³. The shoe width is 620 mm. The toothed-type drive wheels are segmented. The segments are bolted together. This innovation saves time spent on removing and replacing it in case of failure in working conditions. This design allows for the most efficient use of equipment on normal and hard ground.

The undercarriage on the Komatsu D65PX bulldozer is designed to operate in soft, sagging soils. Its guide wheels are slightly shifted forward to increase the contact area, which is now 60,120 cm³. The number of road wheels has reached 16 pieces. Shoe width increased to 920 mm.
