Equipped with a mechanism forced lubrication. Low noise and compliance with all modern environmental requirements, allows it to use it in urban conditions.

Transmission

The Komatsu D65E-12 bulldozer is equipped with a transmission of Torqflow Komatsu's own production transmission. This is a three-element, forcibly cooled by liquid, single-stage, single-phase torque converter. Hydraulic planetary transmission transmission with multi-disc clutch is deprived of mechanical gear flaws. To increase the resource, the box is forcibly lubricated, removing excess heat. The box allows you to work with three front and three reversible transmissions. Management is made by joysticks. To ensure safety, the unit is equipped with blocking levers.

The onboard gearbox is made in the form of planetary and spanning gear, the maximum reducing the possibility of transmitting shock influences into power transmission. Using the experience of past years, segmented the gear wheel, which makes it easily changing the damaged segments in the field.

The control of the bulldozer is performed using the joystick. Light movements in the desired direction allow you to effectively manage a 16 ton machine. This is achieved by advantages of using hydraulic clutch and braking systems. The minimum rotation radius for impressive dimensions is only 3.2.

Chassis

The chassis of the Komatsu D65E-12 bulldozer consists of a pair of tracked ribbons, suspension, supporting rollers, support rollers mounted on a frame of a tracked trolley. The suspension swinging with the balancing bar with the rolling axes installed in front. The design is equipped with the supporting rinks on each side, between them are located 7 on each side of the supporting rollers. The caterpillar consists of 39 units. Connections of the links are made according to a unique technology that impedes ingressing in the compound of abrasive materials.

The frame with a flat bottom is designed in such a way that when working on viscous soils, it prevents increasing under the mud frame. The brake system is represented by multi-disc brakes operating in the oil bath.

Cabin. Bulldozer control

When working on the KOMATSU D65E-12 bulldozer, the operator is as unloaded as possible: a convenient working chair, a ventilation system and air conditioning, an increased control cabin visibility - all this allows you to make it easier to facilitate the operator.

The bulldozer is easily controlled by means of a joystick specially developed by Kamatsu. The joystick clearly reacts to the actions of the operator and with its help the bulldozer is able to easily maneuver on the working surface.

One of the advantages of the design of this model is good amortization and low noise. The control cabin is easily configured under the operator and contains active protection against the penetration of dust into the cab. The basic model of the unit can be equipped with a strengthened cab when necessary for additional protection of the operator.

The control of the operator for the operator at various operating speeds and the amount of material almost remains invisible, which allows you to safely work with the material. Such an effect was obtained by applying the CLSS technology in the production of the hydraulic dump system. It is expressed in the smooth compensation of direct blows of the material in the dump.

A convenient and carefully thought-out electronic fault detection system makes it easier to search for them and eliminate. What in turn allows you to control the resource of the bulldozer as a whole and its parts.

Experience of the bulldozer. Advantages and disadvantages

Bulldozer Komatsu D65E-12 is made by one of the world leaders in the production of bulldozer. All nodes are patented and designed by Komatsu. High-tech nodes, expensive, but simple in replacing and maintenance, there is a system for detecting and controlling faults.

The operator feels comfortable when working in various climatic conditions. All the most critical assembly components are thought out and protected from external influence. In the territory of the Russian Federation, a number of service centers for maintenance of Komatsu technicians are working.
