fuel consumption

Fuel consumption of the Komatsu PC3000 is very modest for its specifications. For simple work, this figure is about 62-68 liters per hour, for heavy work 112-145 liters per hour. The excavator’s fuel tank holds 4,500 liters of fuel.


The special equipment is equipped with an advanced power plant model Komatsu SSA12V159. The 12-cylinder water-cooled unit with direct fuel injection is distinguished by incredible power and performance. With the Komatsu 3000 engine, it can do work that most excavators can’t do. Under the most important features of the engine is the electronic control, which optimizes fuel consumption. Compared to its predecessor, this indicator has been reduced by 10 liters.

Properties of Komatsu SSA12V159 power plant:

  • Working volume – 37.5 liters;
  • Rated power – 940 (1,260) kW (hp);
  • Speed – 1800 rpm;
  • Cylinder diameter – 159 mm.

Access to the hydraulic pumps, which are separated in the Komatsu 3000 model, is greatly facilitated by large internal openings. Multiple passageways and optimal location of the power pack provide maximum access for maintenance and inspection.


The Komatsu PC3000 has an original design that features high quality components and superior reliability. All components are engineered for maximum productivity. Regular analysis of excavator operation has led to significant changes in the design of the COMATSU 3000. It should minimize the number of components that require maintenance. The inspection and repair process itself is made extremely easy and fast, reducing downtime and significantly increasing the useful operating time of the unit. The Komatsu PC3000 Hydraulic excavators have already been operated more than 7,000 times, which is an excellent basis for examining performance and reliability.

The operator’s cabin deserves special attention. It has been enlarged and has huge windows for good visibility. A well-designed layout of homemade bridges and handrails increases operator safety. The operator’s cab itself is protected and tipped from falling objects.

The excavator is equipped with convenient controls. The operator’s efficiency has been improved due to the visual display of instruments, proper placement of levers and joysticks. The driver’s cab has a seat made in accordance with the latest technologies in the field of comfort. Thanks to special mountings, additional soundproofing of the driver’s cab and elastic suspension of the engine, the noise level in the cab is significantly reduced. At the same time, the operator receives comprehensive information about the operating status of the system from the ETM / ECS monitoring system at all times. The information thus obtained, in turn, is used for service/technical analysis.

The Komatsu PC3000 is used with various standby equipment. If you aggregate the units with the direct blade, the functionality is expanded. In this case, the excavator can perform excavation work from the parking level and above. Such devices are used in the development of quarries and pits with work on the ground. Often “Komatsu 3000” is used together with an excavator. At the same time, the range of operations performed differs significantly.

The powerful boom and stick help to increase the productivity of the model. The walls of the Komatsu PC3000 buckets are made of highly durable materials, and the mechanical wear parts are replaced rather quickly.
