Hitachi ZX200-5G: technical specifications, review, description

Excavators

Hitachi wheeled excavators are a series of high-tech and multifunctional machines ZX and ZAXIS-3 series, which have managed to occupy their niche in the middle price segment . This special equipment is aimed at the markets of developing countries, including the CIS countries. Excavators are able to function normally even when using low-quality fuel, which is a big advantage for the domestic market.

Technical specifications Hitachi ZX200-5G, weight

Middle-class technology consistently occupies a dominant position in the Russian Federation. Moreover, over the past 3 years, the share of 20-ton class models in the total sales of mid-size Hitachi ZX machines has grown to 46% (or 27% among all equipment sold). The most popular modification today is the base model Hitachi ZX200-5G with a standard bucket with a volume of 0.8 cubic meters (their share is 20% of all 20-ton trucks).

Compared to its predecessors, the 5 Series machines have become even more economical, and the HIOS III hydraulic system, developed by the company’s specialists, ensures high speed movement of the working equipment. Improved performance is achieved thanks to faster operation of the drives: the speed of movement of the handle is increased due to the mass of the boom during its lowering, as a result, it is not necessary to create additional pressure in the hydraulic system using a pump, which reduces fuel consumption during this operation. In addition, the boom retraction time has been improved (oil flows from the arm and boom hydraulic cylinders are combined through regenerative valves).

Plant for the production of Hitachi excavators in Tver

In Russia, earth-moving equipment is sold both locally produced and supplied from Japan. In 2014, the Hitachi plant was opened in the Tver region, which produces five models of hydraulic excavators: ZX180LCN-5G, ZX200-5G, ZX240-5G, ZX280-5G, ZX330-5G. All other models are imported.

In the production of excavators in Tver, key components (engine, hydraulic system, electrical components) made in Japan are used. At the same time, a sufficient number of components were localized. The next step was taken this year - in the spring, a procurement shop was opened, where sheet steel is now cut, bent and prepared for the welding stage. Booms, handles, rotary platforms and running frames for excavators are made from this steel. This made it possible to localize another stage of production. It is also important that the rolled metal comes from local suppliers. “We strive to develop partnerships with Russian manufacturers, so we already receive some components of our excavators from local enterprises,” the company noted.

Scope of application

Hitachi excavators on a pneumatic wheel base are widely used for the following activities:

• digging pits for subsequent installation of foundations in them;
• development of trenches for pipelines and network communications;
• creation of artificial reservoirs and pools;
• mining in quarries with a small area;
• leveling and leveling of embankments;
• loading and unloading of bulk materials;
• construction of earthen ramparts;
• demolition of buildings using concrete breaking equipment;
• driving piles using a hydraulic hammer;
• drilling wells when installing auger equipment.

It should be noted that the use of machines of this type is especially effective when carrying out excavation work in areas with complex terrain.

Engine

As for the power units of excavators, based on operating experience of the Hitachi ZX200-3 models, it was decided to use mechanical engines with a direct fuel injection system that meet the Tier 2 eco-standard. These diesel engines have a reduced sensitivity of the fuel system, which reduces fuel requirements.

Chassis

The cross-shaped frame of the Hitachi ZX200-5G excavator consists of monolithic plates connected by welding. This guarantees its increased strength and reliability.

The reduction in dynamic impacts is due to the installation of a track tension element. The front guide rollers and hydraulic cylinders of the tie rods are combined in one functional unit, which increases their wear resistance and provides extended service life.

The brackets for guide rollers and travel hydraulic motors are thicker, which has a positive effect on their durability.

The maximum speed of a crawler excavator is 5.5 km/h.

1. A type of earthmoving bucket. The equipment can be equipped with several types of buckets, namely a bucket designed for digging pits, a bucket designed for planning a working area, and a bucket designed for digging trenches. The latter differs from the others only in its width. Such buckets are usually quite narrow. In the basic configuration, the excavator has the first bucket, since it allows you to perform a lot of different tasks related to earthworks.
2. Hydraulic breaker. Almost all modern equipment can be equipped with this equipment. This unit is intended for the destruction of concrete or reinforced concrete structures. This is precisely his main task. However, a jackhammer is often used in road repair work, where it is used to open the asphalt layer of road sections. Some models of such equipment are equipped with a hydraulic rotator, which allows for more precise and accurate work.
3. Hydraulic shears. This equipment is a kind of analogue of a jackhammer, as it is used to perform the same tasks. This unit is most effective in destroying concrete containing reinforcement. This is explained by the fact that the hydraulic cylinders of the jaws allow cutting through iron and steel rods. Just like the hammer, some models have a special rotator.
4. Hydraulic drilling equipment. This type is indispensable in drilling operations. But it is worth noting that the equipment can also be used to loosen solid masses of soil and rocks. Screws are available in various diameters and lengths.
5. Ripping equipment of single-tooth type. As is clear from the name, such a unit is used for loosening hard soil, rocks, and, well, for loosening minerals.

Maintenance

Service intervals for the Hitachi ZX200-5G have been increased from 250 to 500 operating hours. Improvements have also been made to the ergonomics of the cabin: the location of the control levers has been changed, additional compartments have appeared, legroom has been increased, etc.

The Global e-Service remote monitoring system is available for Hitachi machines, providing data on each piece of equipment about its technical and operational condition, maintenance and location. Another service is Consite. With its help, information about the operation of the machine is summarized and monthly reports are generated with a detailed analysis of operational parameters. In addition to these reports, the system also sends notifications about vehicle alarms as they occur directly to the vehicle owner and dealer. Maintenance Pro diagnostic equipment was created to check the condition of equipment.

Additional opportunities to expand the range of activities

The driver's cabin of these excavators is thought out to the smallest detail. The doorway was made even wider, and there was even more space inside. The console is quite compact and does not restrict the operator’s movement. You can easily lift up the windshield and secure it in this position, or open the skylight. Particular attention was paid to ventilation - the shafts are placed so that they ensure uniform air circulation. The domestic analogue of the E200C includes less electronics and automation, but absolutely complies with safety standards. A special word about the operator's seat. Fabric upholstery, armrests, several adjustable positions, the ability to tilt the backrest, shift and even a heating system at the request of the client. All this in a crawler excavator! The control panel is located so that all levers and sensors are at hand and the control process is a lot of fun. The cabin itself is made of high-strength material with additional protection against rollovers and heavy objects falling onto the roof. The cabin is equipped with a multimedia display, where the operator can change the operating mode with one click, selecting any of the 11 offered and using one of the additional equipment.

Modifications of Hitachi ZX200-5G

The company's line includes several main types of Hitachi models:

• basic;
• with an extended undercarriage (designation LC) for work where less ground pressure is required;
• narrow-size (LCN) - narrow chassis (overall width does not exceed 2,500 mm) significantly simplifies transportation on public roads and maneuvering equipment around the site in limited space;
• for severe operating conditions (H), equipped with reinforced working and attachment equipment, additional protective and reinforced elements, a weighted counterweight;
• for dismantling work (K) with pipelines for additional attachments, reinforced working and attachment equipment, additional protective guards and reinforced elements, additional wiper blades and a full-flow filter;
• for heavy duty use with Long Undercarriage (LCH).

Excavator modifications: ZX210K-5G, ZX200-5G and ZX210H-5G

For each model there are several modifications depending on the type of installed working and attachment equipment:

• (SA) - shortened handle with a larger bucket;
• (LA) - extended handle with a smaller bucket;
• (B) / (C) / (D) - various types of buckets other than standard ones.

Russian-made models are available in Standard, LC (long wheelbase), LCH (strengthened version) modifications. All these models can be prepared for work in cold climates (from -40 to +40?). The plant produces models with expanded standard equipment compared to those imported from Japan. A rear view camera and additional lights on the cab are included in the standard equipment package, and additional hydraulic piping for working with a hydraulic hammer, track shoes (from 600 to 800 mm depending on the machine version), and buckets of different sizes and designs are optionally available. Gradually, the plant is developing new options based on requests from customers in Russia and the CIS.

Also in the Hitachi line there are hybrid excavators, which differ from previous models in lower toxicity of exhaust gases and greater efficiency. This technique is gaining popularity in Japan, Europe and Australia, where the cost of fuel is much higher than here. For these countries, purchasing hybrids is a profitable investment in the long term. “Most likely, as control over exhaust emissions and fuel quality increases, these excavators will become interesting in Russia,” explained representatives of the manufacturer.
