Bulldozer KOMATSU D275A-5
Engine of the bulldozer KOMATSU D275A-5
This economical engine, coupled with the heavy weight of the machine itself, makes the D275A-5 a premium crawler-mounted tool for loosening hard rock and. This engine is designed to provide a lower emission level than required by the environmental standard. The engine of the KOMATSU D275A-5 bulldozer is equipped with direct fuel injection, turbocharging and charge air cooling systems, which maximizes fuel economy.
Blade of large capacity
With a dozer blade capacity of 13.7 m 3 (hemispherical) and 16.6 m 3 (spherical), the KOMATSU D275A-5 delivers outstanding performance. The blade front and side cheeks are made of high strength steel for increased structural strength.
The use of a double tilt blade (optional) increases productivity with less effort by the operator:
1. Optimal blade angle for all material types and grades of any grade can be selected on the fly, increasing blade load and machine productivity.
2. Operations including digging, dozing (moving load) and unloading (leveling) are easy and smooth, reducing operator fatigue.
3. The tilt angle of the blade and the speed of its installation are twice the same parameters of the blade with a single tilt.
Comfortable working conditions for the operator

The Komatsu D275A-5 is a heavy tracked tractor designed and manufactured by Komatsu. There are several different modifications of this model. However, the D275A-5 is primarily known as a dozer equipped with an attachable rear opener and replaceable grader.
Reliability, durability, low operating costs and large dimensions have made the Komatsu product one of the most common tracked tractors. Modern bulldozers are far from being "workhorses", but "powerful fireballs" characterized by increased comfort, productivity and high operating parameters. The D275A-5 model is one of the best representatives of this class.
The largest and most important pieces of equipment (hydraulic system, frame, body, etc.) were designed and developed at the Komatsu headquarters. This ensured maximum reliability and performance of the bulldozer with low energy and labor costs.
The Komatsu bulldozer is used to perform quarrying and construction work of various directions: leveling the soil, loosening, moving loads, digging.
Specifications
- D275A-5 is equipped with a powerful 410-horsepower engine. Naturally, this unit consumes a lot of fuel.
- On average, the Komatsu D275A-5 bulldozer requires 55-60 liters (fuel consumption) per hour of operation.
- The fuel tank of the equipment holds 840 liters, which allows it to work without refueling for up to 15-18 hours.
This model is 9290 mm long, 3965 mm high and 4300 mm wide. The bulldozer turning radius is 3900 mm, weight - 50850 kg.
Engine
The D275A-5 is equipped with a 6-cylinder 4-stroke SDA6D140E liquid-cooled diesel engine (manufactured by Komatsu) with a Torqflow hydromechanical transmission. Thanks to the direct fuel injection system and the turbocharging function, the fuel consumption of the model was minimized. The economical motor installed in the Komatsu product, coupled with the huge bulldozer mass, make the Komatsu D275A-5 the best tool for bulldozing and loosening hard soil.
The engine in this technique is mounted on rubber cushions that absorb noise. It is cooled by a hydraulically driven fan. In this case, the system itself selects the required speed of the blades, taking into account the degree of heating of the cooling and working fluids.
Komatsu D275A-5 engine parameters:
- working volume - 15.24 l;
- rated power - 410 hp;
- piston diameter - 140 mm;
Device
A key feature of the Komatsu D275A-5 is the electronic power train control system. SUSP records any operator's action, its duration and frequency. She also monitors the performance of control indicators that are responsible for the state of the system. Based on the received data, SUSP regulates the power of the pulse sent to the side clutches, brakes and gearbox.
The system automatically selects a lower gear when the weight of the load increases while the travel speed is reduced. This feature greatly simplifies the bulldozer control processes, increasing the life of the machine. Thanks to the SUSP, the movements of the Komatsu D275A-5 become smoother. The gearbox of the technique received a special lever that allows you to block the gear change and the neutral blocking switch. These features prevent accidental movement of the machine.
The D275A-5 comes standard with an automatic gearshift switch. There are two similar schemes in the bulldozer. The first is designed for light loads, the second for heavy ones. The switch makes it easier to perform the same type of work, involving a return to the original position.
The Komatsu D275A-5 is equipped with a cylindrical track roller frame and swing-type suspension. Thanks to the K-shaped carriages located in the undercarriage of the equipment, constant contact of the track belt and the support roller is maintained, the vertical movement of the tracks increases, and the slippage of the shoes is reduced. This element also reduces stress on the chassis and vibration transmitted to the body when driving on bumpy surfaces.
The Komatsu product has large spherical blades (13.7 and 16.6 cubic meters) made of heavy-duty steel. The single-shank rippers, also available in the D275A-5, have 3 ranges of plowing depth and plowing angle. Optionally, a double tilt blade can be installed.
This bulldozer combines high productivity with comfort. Komatsu D275A-5 received a roomy cab with great visibility, a spacious seat, adjustable vertically, and armrests adjustable in height. The damping element minimizes vibration and noise in the cab. Thanks to the 150-degree seat swivel function, the operator's field of view is significantly increased. The Komatsu D275A-5 is controlled by the PCCS system built directly into the driver's seat. The human-machine interface ensures precision and ease of operation.
Price
The price of Komatsu D275A-5 varies in the range of 10-15 million rubles. A noticeable influence on it is exerted by the degree of novelty, equipment and year of manufacture.
