Purpose

The Komatsu 220 crawler excavator is most in demand in construction organizations, industrial sectors, mining and deposits. The equipment turned out to be quite multifunctional and is capable of performing work such as digging trenches and foundation pits; creation of embankments of soil and other bulk materials; loading and unloading of any cargo; loosening of rocks and solid soil masses; compaction of loose soils; cleaning areas from industrial waste; leveling the work site; drilling wells of various diameters and depths; destruction of any concrete or reinforced concrete objects and much more.

Device

In the Komatsu PC220, Japanese specialists have implemented a number of interesting developments:

1. equipped with a specialized air filter and air conditioning system that maintain a pleasant microclimate in the cabin. In addition, the operator's cabin is protected to prevent smoke and dust from entering;
2. installation of a modified damper with a longer stroke and additional shock absorption. The solution had a positive effect on the level of vibration and noise, allowing for comfortable unloading and turning of the platform. Strengthening the structure had a beneficial effect on reducing vibration and noise;
3. modernization of comprehensive protection of parts and working units from damage. The hydraulic system of the equipment has complete and enhanced protection;
4. equipping with innovative equipment monitoring and control systems, including functions for storing emergency data and servicing equipment. Automatic performance monitoring is carried out during initial startup and during operation.

The chassis of the model includes a cross-shaped central frame, which has a box shape. The platform is rotated using a hydrostatic drive mechanism. Thanks to its wide support, which guarantees excellent stability, the Komatsu RS 220 can be used when working on loose soil and on slopes.

The steering of the excavator is presented in the form of two pedals and levers. The model retained the hydrostatic drive type. Proportional pressure ensures operator ease and comfort. Mechanisms for moving the levers and sliding the chair help the operator work in a comfortable position.

Scissor car lifts

Mechanisms of this type are used for vehicle maintenance and adjustments.
The advantage is the ability to install flush with the floor surface. Thanks to their special design, they take on a compact form when folded. Many models lift vehicles using a hydraulic drive. The latter provides them with such advantages as complete silence during operation, smooth running, and high durability. There are two types of lifts of this type - stationary and mobile. The latter are used for operational maintenance outside the workshop. These lifts have a lifting capacity of 5 tons. The main disadvantage is the high cost.

Excavator capabilities

Smart design provides quick access to service points. Thanks to this solution, missed repairs and maintenance operations are minimized. The increased distance between the oil cooler and the radiator makes the latter easier to clean. As a standard unit, the Komatsu PC220 is equipped with a water separator, which is used to remove water trapped in the fuel. This element prevents damage to the fuel system.

A unique self-diagnosis monitor shows 39 probable faults and information about the operation of equipment systems. Highly efficient filters are installed in the Komatsu RS 220 hydraulic system and power plant. The fuel tank of the model is additionally treated with a specialized compound that provides additional protection against rust formation and increases corrosion resistance.

The following are installed as standard equipment on the Komatsu PC220:

• automatic air removal system from the fuel line;
• standard capacity batteries;

Table No. 1. Technical characteristics

Power unit

The excavator is driven by a six-cylinder diesel engine of its own production. This is a four-stroke, in-line, water-cooled model. Fuel injection occurs into the cylinders under electronic control. This reduces fuel consumption and reduces the toxicity of flue gases. To increase efficiency, the engine design provides turbocharging with cooling of the incoming air.

Table No. 2. Motor parameters

Chassis

• The rotating platform is mounted on a tracked chassis, which is an X-shaped box-shaped welded frame.
• Hydraulic axial piston motors with final drives and parking brakes, and drive sprockets are mounted on the frame.
• The excavator rests on the ground with rollers through tracks. The tension of the latter is carried out by hydraulic cylinders.

The manufacturer produces 4 standard sizes of shoes: 0.5; 0.6; 0.7; 0.8 m. As the width increases, the weight of the machine increases, but the specific pressure on the ground decreases and stability increases. In total, there are 7 road wheels and 45 shoes per side.

Hydraulic system

The excavator has a closed center hydraulic system with load sensing and pressure compensation valves called HydrauMind. The working fluid is pumped by a variable displacement piston pump. Maximum performance is 439 l/min at rated engine speed. Unloader valves limit pressure in the following circuits:

• actuators - 37.3 MPa;
• movement - 37.3 MPa;
• platform rotation - 28.9 MPa;
• control - 3.2 MPa.

Cabin

According to established tradition, the workplace complies with international standards for ensuring safe work of the operator. The design of the cabin implements the ROPS/FOPS principle of protection against rollovers and falling of heavy objects.

• Panoramic glazing does not interfere with visibility, which makes the car safe for others.
• The hydraulic system is equipped with a locking device, without which the movement of the excavator or actuators is impossible.
• For the convenience of the operator, a sprung seat was installed in the cab, which dampens dynamic vibrations well.
• In addition, the frame itself is not mounted on rubber-metal silent blocks, but on original shock absorbers of its own design.
