Device

The Komatsu excavator is based on a frame made of high-strength steel alloys. All working mechanisms and equipment units are ergonomically spaced across the entire area of the frame. The machine's boom and bucket handle have a reinforced design that allows them to withstand impressive loads. The powertrain, fuel and hydraulic systems are developed in-house by Komatsu. All technological elements are characterized by high wear resistance and reliability. The cylinders of the working mechanisms are equipped with protective rings, which increase their service life and protect them from premature failure. Thanks to the use of advanced Japanese technologies, the excavator's electronic systems have an increased level of reliability and can be safely used in the harsh conditions of the Russian climate.

Cabin

Special attention was paid to the design of the cabin in the excavator, so work in the machine takes place with convenience and comfort. The sealed cabin is optionally equipped with air conditioning. Together with the built-in air filter and increased internal pressure, this blocks dust from entering during active use. High-quality sound insulation minimizes sounds from a running engine and equipment. Thanks to the revised damper with additional spring and long stroke, minimal vibration levels are achieved. The right and left panels feature a reinforced design, which also reduces vibration and noise from the operator's seat.

Multi-position control levers with proportional pressure ensure easy and comfortable operation. The ability to move the levers and the double sliding mechanism of the chair provide maximum ergonomic organization.

The Komatsu PC300's protective characteristics have also been improved:

The cabin received additional protection from falling objects. In addition, the design of the equipment provides for the possibility of installing additional fencing on top;
changing the shape of the rear window mount and removing the right window pillar made it possible to increase the visibility from the operator's cabin by 34%;
a heat shield appeared near the heating areas of the engine and fan drive;
Partitions were installed between the pump compartment and the power unit compartment to block oil splashes on the engine if the hydraulic hose ruptured;
An anti-slip layer was applied to the steps of the equipment, which, together with large handrails, provides strong support.

Description and features

This model is a representative of the middle class of tracked special equipment. The scope of application is not limited to earth-moving work, since in addition, paired with additional attachments, the equipment is ideal for solving other various tasks. The excavator has an optimal balance of operational and technical characteristics. The Komatsu brand also pays great attention to the build quality of its products, which is exactly what is observed in this model. The assembly of each piece of equipment is carried out on automated conveyor lines, where manual labor is extremely small.

As described at the beginning, the Komatsu PC300 is popular in all areas, however, it is most in demand in the mining and construction industries. This is explained not only by the high productivity and reliability of the equipment, but also by the fact that it uses many different modern technologies and solutions, thanks to which the operator or maintenance personnel can monitor the operation of the excavator. This allows you to avoid serious breakdowns that arise in unforeseen situations.

The fuel consumption of the excavator is very low, but it would seem that the power indicators should also decrease, but that was not the case. The manufacturer increased the power of the equipment in active operation mode, and the traction force was increased by 17 percent, as a result of which the equipment is easily able to climb any slope.

The manufacturer also improved the hydraulic system of the excavator, as a result of which it was possible to significantly increase the cutting force on the bucket and handle. When operating at maximum machine power, the cutting force on the bucket increases by 78 percent and at the same time the force on the handle increases by 18 percent. Not every modern technology can boast of such indicators. In addition, the hydraulic lifting capacity has been increased, but this is largely due to the improved lateral stability of the excavator.

The machine has a lot of modern solutions, which, in addition to performance indicators, also affect the simplification of equipment maintenance:

The replacement intervals for lubricating fluids and filter elements, both the power plant itself and the hydraulic system, have been significantly increased.
The standard equipment includes a special moisture separator.
Compared to previous models, this fuel tank capacity has been increased, which allows you to carry out any operations without stopping to refuel.
It is possible to remotely install a special tap, which is necessary for draining fuel and lubricating fluids.
Radiator cleaning has been greatly simplified.

Komatsu 300 has quite a lot of advantages and features, however, the most important of all are:

The cutting force on the bucket and the supporting force on the handle have been increased.
High power of the power plant combined with low fuel consumption.
The lateral stability of the vehicle has been improved.
Overall tractive effort has been increased by 20 percent.

This excavator stands out from its class mainly due to its durability and high reliability, which the manufacturer has achieved thanks to the following:

The excavator frame design is highly durable. Emission microscopy analysis and computer-aided design technology were used to develop the main support structures and chassis.
High-strength working equipment is used. The design of the boom and handle were significantly strengthened, which allowed the machine to work with very heavy loads.
Highly reliable electronic devices were used. These devices were designed specifically for use in rather harsh conditions.
The power plant, hydraulic distributors and hydraulic system pumps are Komatsu’s own developments, which ensures their high quality and, of course, increased reliability.
The hydraulic cylinders use metal safety rings to improve the reliability of the excavator.

The manufacturer also took care of the comfort and convenience of the operator when working. The cabin is sealed and uses a lot of high-quality noise-absorbing and vibration-insulating materials. Thanks to this, it was possible to significantly reduce the noise level arising from the operation of the power plant and working equipment. A damper with an additional spring and a long stroke was also provided, which allows smoothing out strong shocks and shocks during operation, thereby reducing the level of vibrations. This is also facilitated by the side panels of the cab, which use a reinforced structure. An optional air conditioner can be installed to provide comfortable conditions for the operator during the hot season. It has a built-in air filter, which during active operation of the equipment does not allow dust and other small particles to enter the cabin.

Simplicity and convenience during operation were achieved through the use of multi-position control levers with proportional pressure. It is also worth noting the ability to move the control levers and the double sliding mechanism of the chair, thanks to which the operator can set up the workplace as conveniently and ergonomically as possible.

Improvements are also observed in the protective characteristics of the excavator:

The cabin design has additional protection against any falling objects. But optionally, a special frame can be installed to provide increased operator protection.
The operator's view of the work area has been increased by 34 percent. This is because the shape of the rear window mounting has been radically changed and the right side pillar has been removed.
The power plant was shielded with heat-absorbing materials in those places where heating occurs quite quickly and the temperature is very high. This minimizes the risk of fire.
The hydraulic system pump compartment and the engine compartment are separated by a special partition. This solution was used to prevent oil from splashing onto the engine in the event of a hydraulic system hose rupture. As in the previous paragraph, this feature also allows you to avoid the occurrence of a fire.
To make it more convenient and safe for the operator to enter the cab in the winter or in humid climates, the steps were covered with an anti-slip layer.

If we focus all our attention on the technical characteristics of the excavator, then this model is noticeably superior to previous machines. The undeniable advantages of the Komatsu PC300 crawler excavator are high operator safety, build quality and all structural elements, as well as the durability of all components and assemblies.
