Excavator Komatsu PC 400

Komatsu PC400 is the flagship of the Japanese Komatsu corporation. This excavator is distinguished by its excellent performance characteristics, including the maximum radius and depth of soil cutting. The model received innovative solutions and advanced design developments. The automated equipment used to produce the Komatsu RS 400 ensures high build quality. Advanced technical characteristics are achieved through new components and high-quality materials.

The technology provides the opportunity to perform a huge range of work:

• fill in the depressions;
• carry out quarrying;
• Load and unload bulk materials;
• dig trenches, pits and ditches;
• create embankments.

The wide functionality of the Komatsu RS 400 makes it extremely popular in the metallurgical, oil and gas, mining and other industries. The main advantages of the model include:

• maneuverability;
• low fuel consumption;
• minimal toxicity of engine emissions;
• safe and comfortable working conditions for the operator;
• thoughtful design;
• several boom control modes (powerful cutting, smooth cutting);
• ability to work in adverse conditions;
• ergonomic control;
• ease of maintenance.

The excavator also has another important advantage. The improved design of counterweights increased the stability and balance of the equipment, which increased its load capacity.

When creating the Komatsu PC400, the developers paid special attention to reducing the likelihood of emergency situations. For this purpose, steps with a special coating, fences and railings have been added to the design of the excavator. The “highlight” of the model was the HydrauMind hydraulic system with a closed center, two pumps with variable flow and electronic control. It ensures optimal use of the power of the power plant, reducing hydraulic losses during operation and reducing fuel consumption.

Purpose

The Komatsu 400 crawler excavator is very popular in large construction organizations, large-scale industrial sectors, mining, quarries and deposits, metallurgical industries, oil and gas industries and many others where heavy and high-performance equipment is used.

This model is used to carry out tasks such as digging large pits; loosening of solid soil masses and rocks; loading and unloading of any lump or bulk materials; leveling the working area and clearing industrial waste; drilling wells of various depths and diameters; creating embankments of soil and other similar materials; moving various loads over short distances; compaction of loose soil and much more.

The widespread use of the equipment is explained not only by its very high technical characteristics, but also by an impressive range of additional attachments, increased reliability and the ability to work in very difficult conditions.

Engine

The Komatsu RS 400 is equipped with a four-stroke six-cylinder power unit with a capacity of 347 horsepower. The 11-liter SAA6D125E-3 model is equipped with liquid and air cooling systems, direct fuel mixture supply and turbocharging. The maximum speed of the excavator is 5.5 km/h. Fuel injection is carried out using control electronics, which guarantees reduced fuel consumption and efficiency. The engine speed is 1850 rpm, each cylinder has a diameter of 12.5 cm.

The exhaust quality of the power plant complies with international Tier II class standards. Thanks to this motor, the operator can select the operating mode of the Komatsu RS 400 crawler excavator:

• powerful, at which maximum power is generated, ensuring excellent productivity and low diesel consumption;
• Economy mode used for simple work. At the same time, the speed remains the same, and fuel consumption decreases.
