How many lithol in Komatsu 400 tracks. Specifications and dimensions

The Komatsu PC400 tracked excavator is one of the best construction machines from the Komatsu manufacturer. From the entire line of special equipment, this machine is distinguished by excellent operating characteristics, including a large digging radius and maximum cutting depth of the soil. The manufacturer equipped the excavator with innovative solutions and advanced design developments, which significantly increased the reliability of equipment. The process of assembling an excavator is carried out with automated equipment, as a result of which the high quality of the entire Komatsu PC400 was ensured.

Under the hood Komatsu 400 installed diesel six-cylinder engine brand SAA6D125E-3. It uses a system of direct fuel injection into the combustion chambers and a turbocharging system that allows it to develop a rated power of 255.22 kilowatts or 347 horsepower. The engine came out reliable and resistant to high loads. Its operational resource is designed for a rather long service life. Technical problems and faults are solved on the spot, as the design of the excavator provides full access to those parts and components that require regular inspection.

In the Russian markets, this excavator holds a leading position in sales, so it surpasses some import analogs in technical terms, however, the cost is the same, but it can be a little lower.

Purpose

The machine is universal and therefore ideal for almost all areas of work. The excavator is in demand in the construction of any objects, the mining industry, the metallurgical industry, companies for the extraction of gas and oil, as well as in many other industries.

The excavator performs such works as falling asleep holes and recesses; development of quarries and wells; loading and unloading of various bulk materials; digging trenches, ditches and trenches; the creation of embankments of soil and other materials in certain places; dismantling of any concrete structures; as well as road repair, but in this area the machine is used extremely rarely.

Attachment Equipment

The widespread use of the Komatsu 400 tracked excavator is due to the extensive range of various attachments. The machine is able to function with the following additional units:

1. Earthmoving buckets. This type of equipment is basic and there are several models, distinguishable by the type of work being done (digging loose soil or rock), width, full capacity, weight and number of teeth on the lower cutting edge. Installation of units is carried out in just a few minutes.
2. Grab buckets. Such units are mainly used to perform loading operations, to create embankments of soil and cleaning the working area of ​​industrial waste. But besides this, they are also intended for earthmoving works with soils of the first and second density categories. To perform more accurate work, there are models equipped with a special rotator that allows you to rotate the equipment 360 degrees.
3. Loosening equipment. It is an indispensable tool in the mining industry, since it is used to loosen solid rocks of the soil. In addition, it can also be used for demolition purposes.
4. Capture cargo pallet type. The main purpose of such equipment is to perform the loading and unloading of various pallet materials.
5. Hydraulic breaker. The scope of this unit is quite wide, namely, it is often used for the destruction of concrete or concrete structures, for loosening rocks and solid rocks of the soil, as well as for removing the asphalted layer of roads. Some models of equipment are equipped with a special rotator, allowing to perform more accurate work.
6. Hydraulic drilling equipment. This type is used for drilling various wells and loosening rocks. It is applied both in construction, and in various industrial branches. Installed to the handle through a special adapter.
7. Vibrating immersion. There is a fairly large variety of this equipment, distinguishable by size, weight and applied force. Intends for driving in piles.
8. Vibrating tamping units. As with the previous equipment, this one has several models that differ in terms of weight, size, speed of work and effort. The main purpose of tamping aggregates is compaction of loose soils and other similar materials. Used in construction and road repair works.

Modifications

Komatsu 400 tracked excavator is produced in a single version - the base version. The manufacturer did not undertake the development of modified versions, as the base came out quite successful, namely, it has a high power of the power plant and hydraulic system, reliability, comfort of the cabin and, also importantly, versatility. The machine is universal, not only with additional equipment, but also with its standard.

Special features

The Komatsu PC400 tracked excavator has a fairly large number of various improvements, namely:

1. The space in the cabin was increased by 14 percent, which had a positive effect on comfort during operation. The increased volume allows you to adjust the inclination of the operator’s seat with a headrest in almost all the necessary positions.
2. High-quality vibration insulation and noise insulation materials are used, due to which a rather low level of extraneous noise has been achieved during operation arising from unloading operations, rotation of the platform, as well as the engine.
3. In order to increase safety and protect the operator, the cabin frame uses high-strength metal. Moreover, additional upper fences (mounted on the roof) and operator fences may be included in the basic package.
4. Sealed cabin equipped with air conditioning and air purification filter. Due to this, it was possible to avoid dust entering the cab, which also affects its comfort.
5. Special guards in the upper part of the cabin comply with the requirements of the second level according to ISO 10262.
6. The cab uses improved dampers that can significantly reduce the level of vibration arising from the track platform when moving.

One of the key features of Komatsu 400 is to do various jobs with extraordinary precision. This is due to the multi-position control levers for working equipment with proportional pressure. In order for the operator to fully customize the cabin for themselves, the manufacturer installed a double-slip mechanism, the essence of which is to move the operator’s seat and operating equipment control levers apart from each other.

In terms of technical characteristics and performance, there are also several interesting and useful advantages, namely this:

• A certain type of work has its own fulfillment requirements, therefore the Komatsu 400 hydraulic system was equipped with two special boom operating modes. The first mode involves the implementation of a smoother and neat movements when the second is designed for cutting.
• For greater efficiency of the machine, the manufacturer has increased the cutting effort of the soil, which allowed the excavator to cope even with fairly hard rocks and soils.
• The hydraulic system was modified and, as a result, it was possible to significantly increase the maximum capacity.
• To work with a heavy weight, or just on uneven surfaces there is a risk, then at some point the machine may lose its stability and tip over. In order for this not to happen, the entire design of the excavator has been modified. Due to this increased stability.

In terms of maintenance, the Komatsu PC400 excavator will not cause any inconvenience and special work, since the following design solutions have been implemented for ease of maintenance:

1. The equipment bushings have a new modified design, due to which the lubrication interval of mechanisms and parts has been extended. Optionally can install improved items.
2. The use of new filtering elements in the design made it possible to significantly increase the intervals between the replacement of oil filters, hydraulic filters and the power plant filter.
3. The turntable has several accesses to the power unit. With the full opening of the hood, a mechanic can get to almost all elements of the engine.
4. The oil cooler and radiator also have a new redesigned design that allows for quick removal and installation.
5. The high-performance air filter is installed.

And finally, we should mention such qualities of the machine as:

• Maneuverability.
• Efficiency.
• Sophisticated design.
• Ergonomic
• Resistance to environmental influences.
• Minimum amount of engine emissions to the atmosphere.
