ABOUT THE NEW GENERATION OF KOMATSU CRAWLER EXCAVATOR

Currently, motorized machines and especially excavators are an indispensable part in the field of civil, industrial and irrigation construction. In the market with many famous machine manufacturers such as Hitachi excavators, Catterpillar excavators, Kobelco excavators,... Besides, it would be remiss not to mention Komatsu crawler excavator PC300-8M0.

Komatsu crawer excavator PC300-8M0

Komatsu is the world's second largest supplier of construction and mining equipment, after Caterpillar. However, Komatsu has a larger market share than Caterpillar in some regions such as Japan and China. The company currently has many factories and branches in Japan, Asia, America and Europe and is still planning to continue to expand.

Komatsu excavator brand originated from Japan, appeared on the market since 1917. It can be said that this is one of the world's leading brands of excavators, currently competing fiercely with rivals. as big as Hitachi or Catterpillar. Komatsu excavator is considered as a machine with high durability, good working performance and common use. Perhaps that is also the reason why Vietnam and other countries around the world are very fond of the Komatsu line.

Komatsu excavators are specially designed for heavy duty applications. With a powerful engine, sturdy boom and bucket design, bearing iron material ensures workability and productivity in all cases. Along with compact structure and superior features, the company's machine can be widely applied such as: bridge construction, road construction, construction work in residential areas. The machine has many working modes with different engine speed and hydraulic system pressure to meet different conditions. In the fuel-saving mode, the machine still works effectively, in the heavy-duty mode, the machine can operate with the largest capacity, helping the digging and lifting force of the machine can be increased many times.

HIGHLIGHTS

ECOLOGY, ECONOMY & PRODUCTIVITY

Low Fuel Consumption

The newly-developed Komatsu SAA6D114E-3 engine enables NOx emissions to be significantly reduced with the accurate multi-staged fuel injection by the engine controller. It improves total engine durability using the high-pressure fuel injection system developed specifically for construction machinery. This excavator significantly reduces hourly fuel consumption using the highly-efficient matching techniques of the engine and hydraulic unit and also provides features that promote energy-saving operations such as the E mode and ECO gauge.

Fuel consumption: 3% reduced Vs. PC300-8, based on typical work pattern collected via KOMTRAX. Fuel consumption varies depending on job conditions.

Komatsu Technology

Komatsu develops and produces all major components, such as engines, electronics and hydraulic components, in house. With this “Komatsu Technology” and adding customer feedback, Komatsu is achieving great advancements in technology. To achieve both high levels of productivity and economical performance, Komatsu has developed the main components with a total control system. The result is a new generation of high performance and environment-friendly excavators.

Low Emission Engine

Komatsu SAA6D114E-3 reduced NOx emission by 33% compared with the PC300-7. This engine is U.S. EPA Tier 3 and EU Stage 3A emissions equivalent.

Low Operation Noise

Enables a low noise operation using the low-noise engine and methods to cut noise at source.

Idling Caution

To prevent unnecessary fuel consumption, an idling caution is displayed on the monitor, if the engine idles for 5 minutes or more.

ECO Gauge that Assists Energy-saving Operations

Equipped with the ECO gauge that can be recognized at a glance on the right of the multifunction color monitor for environmentfriendly energy-saving operations. Allows focus on operation in the green range with reduced CO2 emissions and efficient fuel consumption.

Working Modes Selectable

The PC300-8M0 excavator is equipped with six working modes (P, E, L, B, ATT/P and ATT/E mode). Each mode is designed to match engine speed and pump output to the application. This provides the fexibility to match equipment performance to the job at hand.

- P: Maximum production/power, fast cycle times.

- E: Good cycle times, better fuel economy, adjustable in 4 stages.

- L: Suitable attachment speed

- B: Optimum engine rpm, hydraulic flow.

- ATT/P: Optimum engine rpm , hydraulic flow, 2way, power mode.

- ATT/E: Optimum engine rpm, hydraulic flow, 2way, economy mode

Large Digging Force

When press the left knob switch which is called the one-touch power max. switch and when it is kept pressed, this function temporarily increases digging force for 8.5 seconds of operation. Large Digging Force

- Maximum arm crowd force (ISO 6015): 160 kN (16.3 t) => 171 kN (17.4 t) (With Power Max.)

- Maximum bucket digging force (ISO 6015): 212 kN (21.6 t) => 227 kN (23.1 t) (With Power Max.)

Measured with Power Max. function, 3185 mm arm and ISO 6015 rating.

Smooth Loading Operation

Two return hoses improve hydraulic performance. In the arm out function, a portion of the oil is returned directly to the tank providing smooth operation.

Two-mode Setting for Boom
