The Komatsu PC200 excavator is a hydraulic machine for road construction works weighing 19.8 tons. The unit is part of the Galeo line with increased performance and efficiency and complies with environmental standardization standards. As a result, the emission of nitrogen oxides is reduced by 20–30%.

The model is equipped with a SAA6D107E-1 diesel engine and develops 141 hp at a crankshaft speed of 2000 rpm.

Engine parameters SAA6D107E-1:

• engine displacement – 6.69 l;
• piston diameter — 107 mm;
• piston stroke — 124 mm.

The fuel tank is designed for 400 liters, and the hydraulic tank – is for 135 liters.

The fuel consumption of Komatsu PC200 depends on the conditions of use and is reduced by 7% according to the calculated information received by the KOMTRAX system.

The basic delivery set includes the following items:

• 1-section boom 5.7 m long;
• interchangeable handles – 1.84, 2.41, 2.93 m;
• multifunction bucket — 0.8 m3.

The specialized working mechanisms Komatsu 370E and Komatsu S132 allow you to use the PC200 excavator for logging work effectively.

The Komatsu PC200-5 modification is a fifth-generation unit with a mass of 18.9 tons and an engine power of 110 kW.

The Komatsu PC200-8M0 has been replaced by a new model – the Komatsu PC210-10M0 crawler excavator. Both machines are designed for industrial and civil construction, but the PC210-10M0 compares favorably with its predecessor in critical features.

The Komatsu PC210-10M0 has a 25% increase in bucket capacity compared to the Komatsu PC200-8M0 to 1.0 m3. Accordingly, the productivity of the machine increased by the same amount.

Both models of excavators have two engine modes for cutting soil: economic and high power. But the PC210-10M0 has added another one – the full power mode.

It turns on for 8.5 seconds, during which the ground cutting force is increased by 36% compared to the economy mode and 19% to the power mode.

This mode was implemented by increasing the total engine power in the Komatsu PC210-10M0 by 12% compared to the Komatsu PC200-8M0: from 110 kW to 123 kW.

Another distinguishing feature of the Komatsu PC210-10M0 is the length of the counterweight increased by 150 mm. As a result, the operating weight of the excavator with the main working equipment has also increased from 19,800 kg (for Komatsu PC200-8M0) to 20,400 kg. The extended counterweight length, combined with the greater machine weight, improves machine stability and increases payload capacity by 5% compared to the Komatsu PC200-8M0.

Excavators Komatsu 220, 220-7, and 220-8 are building units with an operating weight of 23.2 tons, assembled according to a single design scheme. Therefore, technical parameters do not differ from each other.

The PC220 general purpose hydraulic machine is equipped, like the PC 210 and 200 units, with the SAA6D107E-1 power unit, developed by the manufacturer and reducing nitrogen oxide emissions by 29% due to precise multi-stage fuel injection, which the controller controls.

The high-performance diesel-hydraulic matching method reduces fuel consumption per working hour by 5%, and the economy mode with ECO-pointer function works energy-savingly.

The power of the low-toxic engine reaches 168 hp.

Tractor travel speeds:

• maximum — 5.5 km/h;
• automatic switching in the middle range – 4.2 km/h;
• minimum — 3.1 km/h.

The machine is highly maneuverable and can overcome slopes and slopes with a steepness of up to 70o.

The basic package includes a bucket with a volume of 0.72-1.26 m3, a 1-section boom with a length of 5850 mm, and a 700 mm wide shoe with three grousers.

The excavator allows aggregation with multifunctional buckets for special purposes:

• for cleaning and cleaning pits and trenches with a “cap” (capacity – 0.7-0.8 m3, width – 1800 mm);
• for finishing slopes (bucket volume — 0.35–0.4 m3, width — 2000 mm);
• trapezoidal bucket for laying ditches and drainage works (volume — 0.5–0.7 m3);
• with baking powder (capacity – 0.56–0.62 m3, width – 990 mm);
• one-, three-tooth rippers for crushing rocks, cutting the hard top layer of soil.

Komatsu PC300, 300-7, and 300-8 excavators are reliable units for general construction operations. They are equipped with a more powerful and efficient SAA6D114E-3 engine with the following characteristics:

• working volume – 8.27 l;
• piston diameter — 114 mm;
• piston stroke — 135 mm.

The operating weight, taking into account a 1-section boom with a length of 6470 mm, a handle – of 3185 mm, and a bucket with a capacity of 1.4 m3, has the following indicators:

• for PC300-7–31510 kg;
• for PC300-8–31100 kg.

The fuel tank capacity reaches 605 liters, the coolant tank – is 31 liters, and the hydraulic tank – 188 liters.

The machine moves at a speed of 5.5 km / h and overcomes ups and downs with an inclination angle of 35.

Basic bucket – 2.2 m3. For work with hard and rocky rocks, the excavator is equipped with a bucket with a special-purpose baking powder with a capacity of 0.7–0.8 m3 and a width of 1200 mm.

Komatsu PC400 Service Manual PDF

Service manuals for Komatsu PC400 are available for download above.

The Komatsu 400 excavator and its modifications PC400-6, 400-7, 400-8 are heavy-duty machines for use in the mining industry and the construction of large facilities. They weigh about 42 tons and are equipped with a turbocharged diesel power plant rated at 246 kW, or 335 hp.

The Komatsu PC400-7 model is a 7th generation front shovel excavator for excavating the soil layer above the state of the art. In this version, the bucket with a capacity of 1.3-2.2 m3 is fixed on the handle, moves away from the unit, and a hydraulic cylinder performs unloading by tipping. This design provides a large cutting and digging force on the bucket and reduces the number of work cycle operations.

When the system switches to the active mode, the push force of the handle increases by 8%, the cutting force – by 9%, compared with the machine of the 6th generation.

The arrow works in 2 modes:

• powerful cutting of soil;
• smooth operation.

Low fuel consumption is achieved by electronically controlled fuel injection.

The fuel tank capacity of the Komatsu PC400 excavator has been increased to 650 liters. As a result, fuel consumption was reduced by 20%.

By increasing the weight of the counterweight to 330 kg and improving the balance of the hull, an increase in the transverse stability of the machine was achieved.

The cabin volume has been increased by 14%, which provides better comfort and convenience at work. In addition, vibration at floor level has been reduced from 120 to 115 dB.
