Highly efficient and modern Komatsu bulldozers are used in various fields of industry and the national economy. The tractor has established itself as a reliable, easy-to-use and easy-to-manage unit. The machine is equipped with modern power devices, has several configurations. The equipment is designed for operation in various climatic regions.

Features

Bulldozers Komatsu is produced by the world leader in the field of transport industrial equipment. All technical and auxiliary units combine ease of maintenance, while each of them is patented, made using high technology. The tractor is equipped with a fault detection system, which increases the speed of troubleshooting several times.

For the driver, the seat is equipped with various thoughtful elements and is protected from external influences, which allows you to comfortably work in various conditions. The considered bulldozer, created in the Land of the Rising Sun, has an increased resource due to the use of innovative solutions using composite materials. Variations with a complete set allow you to choose a model,optimally suited for certain types of work. The unit can be equipped with a baking powder, attachments and other additional equipment.

Modifications

Komatsu bulldozers, the range of which includes special equipment of various categories, can handle loads from eight to hundreds of tons. In terms of power, modifications from 80 to 900 horsepower are presented. The most popular in the domestic market are the Komatsu d65 bulldozers.

They are heavy-duty multifunctional special equipment used for various types of bulldozer work. The crawler assistants can be equipped with various types of front blades with adjustable angle and tilt, as well as upgraded elements that significantly increase the productivity of the machine.

In addition, the following modifications are in demand:

• D65E;
• D355A;
• D275;
• D375;
• D475.

They all have their own characteristics and applications.

Key technical data

Komatsu bulldozers, the technical characteristics of the main plan of which are presented below, in the most popular configuration have the following indicators:

• The power of the power plant is 207 horsepower. (1550W);
• Total weight with attachments - 19.7 tons;
• Track/track width – 1.88 /0.51 m;
• Ground clearance - 425mm;
• Straight blade: width/height (mm) - 3415/1225;
• Equipmentrotary type: width/height (mm) – 3970/1100;
• Semi-spherical element (similar indicators) - 3870 and 1235 mm;
• Bucket lifting height my maximum above ground level is 1100 mm;
• The maximum depth of immersion of the bucket in the soil is 505 mm;
• Opening mechanism - three-stage version with a maximum lift of up to 640 mm and a depth of 595 mm.

Bulldozers Komatsu D65E 12 have: length - 6, 6, width - 3, 1, height - 3, 46 meters.

Power plant and transmission assembly

The tractor is equipped with a four-stroke diesel engine with direct fuel injection and water cooling. The frequency of rotation of the unit per minute is 1950 scrolls on the flywheel, the power is 135 kW with a fuel consumption of 180 g per hour. The unit is considered one of the most economical in its class, while the maximum torque reaches 799 Nm at 1,100 rpm. Engine lubrication system - forced type, low noise threshold allows the use of equipment in urban areas.

Popular Komatsu bulldozers are equipped with native TORQFLOW transmission. The assembly is a hydraulic single-stage transformer with three elements. The planetary type hydraulic drive gearbox is interconnected with a multi-plate clutch unit and has forced lubrication. The gearbox operates in three forward and as many reverse positions.

The reducer on board the tractor is a planetary and spur gear arrangement that minimizesshock effects on the power unit. The bulldozer is controlled by a joystick. Elementary movements in the desired direction make it possible to easily and effectively control a multi-ton machine. This is due to the advantage of introducing hydraulic brakes and clutches into the design.

Cabin arrangement

The operator's workplace is a cab with a comfortable chair, air conditioning, ventilation system, joystick for tractor control, and other functional and control devices.

Additionally facilitates the work of the bulldozer increased visibility, excellent shock absorption, as well as thoughtful protection against dust and noise. The cab is easily adjusted to the physical characteristics of the driver, can be produced in a reinforced form to work in particularly difficult conditions.

Dump control is carried out by adjusting the speed and weight modes, which makes it possible to accurately work with various materials. A similar effect, which is expressed in the smooth compensation of the mechanical impact of the processed products, was obtained thanks to the specially developed CLSS technology used in the manufacture of hydraulic units. Many levers, sensors and instruments help to correctly adjust the work, taking into account their performance and features.

Advantages of the considered technique

Komatsu bulldozers have a number of objective advantages, which are in the following positions:

• Excellent power of power plants that guarantee highunit performance.
• Good economy and low maintenance.
• The introduction and use of motors, as well as other important components of our own manufacture, which increases their reliability and suitability for repair.
• The use of various types of interchangeable attachments is allowed, which expands the functionality and scope of the machine.
• High quality of the main units and assemblies, as well as additional equipment, ensuring reliability and long-term operation.
• The low center of gravity of the machine and the design features of the crawler chassis give the tractor reliable stability during the work process.

Reviews

Most of the reviews about the Komatsu technique are positive. Especially users note the advantages listed above, as well as the comfort of the driver, the variety of configurations, the modern design of the cab and its ergonomics.

In addition, the full operation and repair of this machine in domestic conditions can be organized thanks to open service centers, and the cost of the unit is quite acceptable for equipment of this category, since the production of spare parts and components has been established in Yaroslavl, the head office is located in Moscow.

Finishing

We can safely say that the Japanese Komatsu bulldozers, the overall dimensions of which depend on the modification and have a fairly wide range, are reliableand functional machines.

When a modern tractor is required for various industries, the choice of the considered unit is almost the best solution, considering the performance, ergonomics, compliance with world standards, economy, quality of parts and the total cost of this vehicle.
