Highly efficient and modern bulldozersKomatsu is used in various spheres of industry and national economy. The tractor proved itself as a reliable, easy-to-use and easy-to-operate unit. The machine is equipped with modern power devices, has several complete sets. The technique is designed for operation in different climatic regions.
Features
Bulldozers Komatsu produces world leader insphere of transport industrial equipment. All technical and auxiliary units combine the simplicity of service, while each of them is patented, implemented with the use of high technologies. The tractor is equipped with a fault detection system, which increases the speed of their elimination several times.
For the driver the seat is equipped with variousthoughtful elements and protected from external influences, which makes it possible to work comfortably in different conditions. This bulldozer, created in the Land of the Rising Sun, has an increased resource, thanks to innovative solutions using composite materials. Variations with bundling allow choosing a model that is optimal for certain types of work. The unit can be equipped with a baking powder, hinged nozzles and other additional equipment.
Modifications
Komatsu bulldozers, a lineup of whichincludes special equipment of various categories, can handle loads of eight to hundreds of tons. According to the power indicators, modifications from 80 to 900 horsepower are presented. The most popular on the domestic market are bulldozers Komatsu d65.
They are a multifunctionalspecial equipment of heavy category, used for different types of bulldozer works. Crawler assistants can be equipped with various types of front piles with adjustable angle and tilt, as well as modernized elements that significantly increase the productivity of the machine.
In addition, the following modifications are required:
- D65E;
- D355A;
- D275;
- D375;
- D475.
All of them have their own peculiarities and spheres of application.
Main technical indicators
Komatsu bulldozers, whose main plan technical characteristics are presented below, have the following indicators in the most popular equipment:
- Power of the power plant - 207 horsepower. (1550 watts);
- Total weight with mounted units - 19.7 tons;
- The track / track width is 1.88 / 0.51 m;
- Ground clearance - 425 mm;
- Straight blade: width / height (mm) - 3415/1225;
- Equipment of swivel type: width / height (mm) - 3970/1100;
- The hemispherical element (similar indicators) is 3870 and 1235 mm;
- The height of the bucket lift is maximal above the ground level - 1100 mm;
- Limiting depth of submergence of a ladle in soil - 505 mm;
- The disintegration mechanism is a three-stage version with a maximum lift 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 powertrain assembly
The tractor is equipped with a diesel four-strokea motor with direct fuel injection and water cooling. The speed 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. Installation is considered one of the most economical in its class, with a maximum torque of 799 Nm at 1,100 rpm. Engine lubrication system - forced type, reduced noise threshold allows to use the equipment in urban conditions.
Popular Komatsu bulldozers are equipped with nativetransmission TORQFLOW. The unit is a hydraulic single-stage transformer with three elements. The hydraulic transmission of the planetary type is interconnected with the multi-plate clutch unit, it has compulsory lubrication. The CAT operates in three forward and as many reversible positions.
Reducer on board the tractor is a layoutplanetary and spur gear, which minimizes shock impacts on the power unit. The bulldozer is operated by means of the joystick. Elementary motions in the desired direction make it possible to easily and effectively control a multitone machine. This is due to the advantage of introducing brake and clutch hydraulics into the design.
Cabin arrangement
The operator's workplace is a cabin in which there is a comfortable chair, air conditioning, ventilation system, joystick for tractor control, other functional and control devices.
Additionally facilitates the work of the bulldozerincreased visibility, excellent shock absorption, as well as well thought-out protection against dust and noise. The cab is easily adjusted to the physical characteristics of the driver, can be produced in an enhanced form for work in particularly difficult conditions.
Control of dumps is carried out by means ofadjusting the speed and weight modes, which makes it possible to accurately perform work with various materials. Such an effect, which is expressed in the smooth compensation of the mechanical effect of the processed products, is obtained thanks to the specially developed CLSS technology used in the manufacture of hydraulic assemblies. A lot of levers, sensors and devices help to correct the work correctly taking into account their indicators and features.
Advantages of the considered equipment
Komatsu bulldozers have a number of objective advantages, which consist in the following positions:
- Excellent power of power plants, which guarantee high performance of the unit.
- Good indicators of profitability and operational simplicity.
- The introduction and use of motors, as well as other important components of their own making, which increases their reliability and suitability for repair.
- The use of various types of attachments, which expands the functionality and the scope of use of the machine.
- High quality of the main units and components, as well as additional equipment, ensuring reliability and long-term service life.
- The low center of gravity of the machine and the design features of the tracked chassis give the tractor reliable stability during the working process.
Reviews
Most reviews about the Komatsu techniquedifferent positive character. Especially users note the advantages listed above, as well as the comfort of the driver, the variety of complete sets, the modern design of the cabin and its ergonomics.
In addition, full operation and repairThis machine is available in domestic conditions due to open service centers, and the cost of the unit is quite acceptable for this category of equipment, since the production of spare parts and components in Yaroslavl has been adjusted, the head office is located in Moscow.
Completion
It is safe to say that Komatsu Japanese bulldozers, the overall dimensions of which depend on the modification and have a rather wide range, are reliable and functional machines.
If required for work in various industriesmodern tractor, the choice of the considered unit is almost the optimal solution, given the performance, ergonomics, compliance with international standards, efficiency, quality of parts and the total cost of this vehicle.
