Appointment
The Komatsu PC200 excavator is designed exclusively for the construction of any objects, including road sections.
This excavator is used for almost all construction purposes, namely, it is capable of doing not only excavation work, which includes digging trenches and pits, but also dismantling. This is due to the presence of special attachments (either a hydraulic breaker or hydraulic shears) that can handle concrete, rebar and other similar materials. Also, this technique, due to a fairly extensive set of buckets, can perform leveling work, which is a fairly frequent process in construction and industry. Drilling work can also be done with this excavator, since, in addition to buckets and dismantling tools, it can also use special hydraulic drilling equipment, which makes it possible not to resort to the use of other equipment, if, of course, such equipment is available and installed on the machine.
Attachments
As described above, the Komatsu 200 excavator is an indispensable machine in the field of construction work, as it has versatility. And for good reason, because this car can use a variety of attachments designed for a particular process. The list of these auxiliary units includes the following type of equipment:
- Digging bucket. It is a standard unit of this excavator and is designed for digging pits and trenches. It can also be used for loading or moving over short distances of various bulk materials in their structure. Has several teeth, usually no more than six. There are several versions with different sizes and number of teeth. Fits to the handle without a special adapter.
- Grading bucket. This equipment has a small volume and no teeth. The main purpose of this bucket is to perform leveling work. There are also several versions that differ in volume and size. Fits to the handle without a special adapter.
- Hydraulic breaker. It is one of the main tools for demolition work. Able to cope with both concrete and reinforced concrete structures.
- Hydraulic shears. Just like the previous equipment, it is one of the main units used in the dismantling of any objects. In addition to the destruction of concrete and reinforced concrete structures, it can also be used for dismantling railways, since the force of this equipment allows you to bite rails. For more precise work, the scissors are equipped with a rotator that allows you to select the required angle. Installed to the handle using a special adapter.
- Drilling equipment. This type equipment is not used as often as previous units, but you can still find it. This unit is intended for drilling different soil structures. Installed to the handle using a special adapter.
- Loosening equipment. It is an indispensable equipment when working on fairly dense ground. There is only one version of this unit, namely this single-tooth type. Fits to the handle without a special adapter.
Of course, the Komatsu 200 excavator has a wide range of various attachments, but some units were not included in this list, since all of the above are commonly used equipment.
Modifications
The Komatsu PC200 excavator has no modified versions, there are only several generations of this model. But there is one version that can still be called a kind of modification, namely this Komatsu PC200 / 7LC. This model differs from the basic excavator in technical characteristics, including overall dimensions. In length, the car has become much larger, this is due to the elongated tracks, which is exactly what the abbreviation LC indicates in the model name. A 143-horsepower diesel power unit is installed on the turntable at the rear, equipped, like in the base excavator, with a turbocharging system. But it is worth noting that this unit is slightly weaker than the base unit, but this does not affect the work in any way.
Of the available functions, you need to pay attention to new system fuel economy that saves up to 20 percent in diesel fuel. The whole point of this option is as follows: if, after work, the levers responsible for the movement of the machine and the operation of the attachment were transferred to the neutral position, then the number of crankshaft rotations will automatically be reduced to medium speed. But if the levers are inactive for four seconds, the system will automatically switch the engine to idle, but after changing the position of the levers, the engine will be put back into normal operating mode.
Specifications
In a fully operational state, the Komatsu 200 excavator weighs 19,200 kilograms, but this takes into account the 500 mm track shoes. The machine can be equipped with wider shoes for increased flotation. There are three values in total, these are 600 millimeters (the mass grows to 19300 kilograms, and the pressure exerted on the ground decreases to 44.1 kilopascals), 700 millimeters (while the weight of the excavator is 19550 kilograms, and the pressure on the ground is 38.2 kilopascals). Well, and 800 mm shoes, with which the excavator has a mass of 19,810 kilograms and a specific pressure of 34.3 kilopascals. On standard 500 mm shoes, the Komatsu 200 excavator exerts a specific ground pressure of 53.0 kilopascals.
The excavator has a length of 9480 millimeters, when the length along the supporting surface is 6270 millimeters. The height of the machine to the highest point of the boom is 2,985 millimeters when the height across the cab is exactly 3,000 millimeters. The width of the excavator is 2800 millimeters. The ground clearance calculated under the counterweight is 1,085 millimeters. The minimum ground clearance is 440 millimeters. The turning radius of the rear platform has a value of 2750 millimeters. The reference track length is 3270 millimeters, when the overall length is 4080 millimeters. The track spacing is 2200 millimeters. The track width is 2800 millimeters. The lug height is 26 millimeters. The height of the cabin itself is 2095 millimeters, and its width is 2710 millimeters. The machine platform can rotate at a speed of 12 revolutions per minute.
The standard excavating bucket has a volume of 800 cubic millimeters. The maximum allowable dumping height is approximately 7110 millimeters. The maximum depth is 6620 mm. The maximum radius is 9875 millimeters, while the minimum is 3040 millimeters. The excavator equipment has a lifting capacity of up to 6750 kilograms. The hydraulic system holds 143 liters of fluid. A hydraulic system pump is installed, the capacity of which reaches 428 liters of fluid per minute. The fuel tank can hold up to 400 liters of fuel. The cooling system tank has a volume of 20 liters.
Peculiarities
The Komatsu PC200 excavator is a highly reliable and productive machine that has a large number of modern technologies, as well as innovative ideas. The main feature of this excavator is a special system with which it is possible to achieve diesel fuel savings of up to 20 percent by automatic switching engine idling. This occurs if the control levers of both the machine and the equipment are in neutral for more than four seconds. There is also a system for automatic adjustment of power, speed and effort when digging, which also affects fuel economy during operation.
For the convenience of servicing, several special handrails and anti-slip pads were installed in the engine compartment on the upper platform, which ensured safe movement. There is also easy access to the power unit and all necessary filters, thanks to the hatches located on the sides of the excavator platform. It is worth noting that thanks to this, you can get to the rest of the important mechanisms and systems.
Noise-insulating porous materials are used in the cab, which can significantly reduce the noise level during operation. This, in turn, provides a comfortable working environment for long periods of work. A fairly large glazing area provided a large all-round view from the workplace. It is also worth paying attention to the fact that in the cab of this excavator there is a locking system for levers and other controls, which prevents accidental pressing when entering the cab. Before starting work, you should check whether the lever of this system is in a horizontal position, if not, then move it.

In this model, the developers have implemented a fairly large number of modern solutions and innovative ideas, which also allowed the technology to take a leading position in the world market. In the Komatsu 200, a mechanism for automatic adjustment of the digging force was applied, the hydraulic power of the digging system was increased and the intervals for parts replacement were extended.
Moreover, the excavator has received three different operating modes, which allow you to select the optimal engine speed and set the required pressure in the hydraulic system. This allows the machine to be configured for certain types of tasks.
Let's take a closer look at each mode:
- Mode A. This mode is active, that is, it achieves maximum power indicators and productivity. This has a positive effect on the speed of the full cycle, but it should be noted that the specific fuel consumption increases slightly.
- Mode E. Represents the economical operation of the excavator. If we compare it with the previous regime, then in this particular fuel consumption is reduced by 20 percent and, moreover, the amount of toxic emissions is much less. With all this, the machine has its standard performance.
- Mode B. This mode is mainly designed to work with a hydraulic breaker, as it allows you to select the optimal pressure of the hydraulic system and the speed of rotation of the crankshaft of the power unit.
It is worth noting that there is also a maximum cutting force function, which increases the force on the bucket when digging by 7 percent. This is especially useful when working on hard ground or rock formations.
The manufacturer also focused on the comfort of the machine when working. There are special handrails with anti-slip pads for safe movement on the turntable near the engine compartment.
The service personnel will not have any problems when servicing this model, since there is full access to all the most important components and mechanisms, as well as to various filters. All access is provided by access doors located on the sides of the turntable and at its platform.
Each door has a sound-insulating porous coating, as a result of which the noise level of equipment operation has been significantly reduced.
The most sophisticated element of the whole design is the operator's cab. Its distinctive features are the verified ergonomics of the controls and a fairly large all-round visibility. In order to increase safety, the manufacturer has used a so-called "mini-barrier" at the entrance to the cab, which prevents accidental movement of the control levers.
On the side of the operator's seat, there are several modern small-size displays, on which all information about the technical condition of the machine is displayed. The operator's seat is air-suspended and fully adjustable with armrests.
It is worth noting that the seat can be moved with or without control levers, which is quite convenient. In the cab, the level of extraneous noise and vibrations arising during the working process is quite low.
This was achieved through the use of a sprung platform and a multilayer spring-hydraulic system.
The cabin has a hatch with a window, which, if necessary, can be opened and fixed in the open position. The same applies to the door leaf. The design of the cab itself is very sealed, which allows the operator to do any work with maximum comfort in very dusty conditions.
At the request of the client, the excavator is additionally equipped with a radio tape recorder and air conditioning. The operation of this model can take place not only during the day, but also in dark time days or in conditions with poor visibility. This is because bright headlights are installed on the cab, boom and turntable.
For added convenience, rear-view mirrors are installed, however, they are used only during daylight hours.
The hydraulic system is monitored electronic system HydrauMind. This was applied in order to reduce fuel consumption during operation. There are valves that monitor the degree of load, which serve to increase or, conversely, reduce the performance of the motor and hydraulic system. This feature is one of the key benefits of the Komatsu 200 excavator.
The manufacturer has increased the reliability of the working parts of the machine by using the continuous welding method, which also has a positive effect on reliability.
The improved hydraulic system allows you to perform any action with maximum precision, which is undoubtedly a big plus.
The excavator showed this advantage even at the presentation, when it was required to carefully cut the watermelon, which the equipment coped with perfectly.
Among its class, Komatsu PC200-7 stands out with its modern diagnostic system, thanks to which the timing of replacement of filter elements, oil and much more is fully monitored. As a result, the time required to diagnose the entire excavator is significantly reduced.
Even in the basic configuration this model It is quite multifunctional, however, to expand the scope and additional convenience, the following is optionally installed on the equipment:
- Handles of various lengths.
- Window heating system.
- Air conditioning.
- Accessories for the cab, designed to protect from sunlight and rain.

This excavator is in high demand on the world market. This is due to the fact that the technique ideally combines high reliability of the entire structure, modern appearance, excellent efficiency and very good power indicators.
A six-cylinder diesel engine of the SAA6D102E-2 brand is installed under the hood of the vehicle. This power unit was developed by Komatsu and is turbocharged with charge air cooling.
The engine complies with Tier II environmental standards, which is just valid in the territories of Japan, America and Europe. Fuel system has a special moisture separator that removes all water from the fuel.
This element is found in many modern cars, as it also affects the proper operation of the power plant.
In addition to turbocharging, this engine has a system of direct fuel injection into the combustion chambers and liquid cooling. There is also a modern control system that has a positive effect on fuel consumption.
