Excavator Hitachi (Hitachi): specifications. Japanese machinery

Construction works are always closely connected with the development of the soil, which is impossible without excavators – earth-moving machines of cyclic action. They are designed to move bulk materials, digging Foundation pits, trenches, excavate rocks, clearing the roads, construction of embankments and other operations. Therefore, when choosing this equipment should give preference to proven and reliable instances.First and foremost, pay attention to Japanese cars of Hitachi – world-renowned manufacturer of special vehicles. Excavator “Hitachi” – is a reliable, hardy and undemanding worker who can handle any task correctly in a short time. A huge range of earthmoving vehicles of the group will allow you to select the instance to work in different environments.

Types of excavators

The Financial and industrial group Hitachi there since 1910. For all time of its existence it has accumulated vast experience in construction machinery production. The company embodied innovations and proven technologies. Therefore, the popularity of Japanese machinery is growing every year.

The model number of the machine-building concern, the instances are divided according to their size. Thus, there are small, medium and large excavator "Hitachi". The first type is designed for operation in cramped urban conditions. Their dimensions may not exceed the dimensions of the car. These representatives are used for laying, digging shallow trenches.Special Equipment medium size has a broader scope. It can be used on large building sites, in small quarries, on priemootpravochnyh stations and in other areas. Large excavators are usually used for the extraction of minerals by open method. Their weight reaches 800 tons and the duration of continuous operation can amount to more than a day.

Excavators ZX series

Wheeled excavator “Hitachi” – usually, the technique of medium and small sizes. All models are available in two series – and ZAXIS ZX-3. Special equipment ZX range is characterized by the following indicators:

• Operating weight – from a 13.4 to 20.3 tonnes;
• Work bowl capacity – from 0.5 to 0.8 cubic meters;
• Maximum digging depth – from 5.05 to 6.42 meters;
• Powerplant – 4 or 6-cylinder turbocharged diesel engine with water cooling.

For the development of soil hydraulic system responds with suction and polnoprotochnogo filters. Regulation of power and speed is a stepper motor. Wheeled excavator “Hitachi ZX” works in two modes – the digging mode or when using attachments.All members of the series are equipped with shockproof valve, quick warm-up two axial-piston pumps with differentiated performance and a turntable.

Series excavators ZAXIS-3

Wheel excavator ZAXIS-3 is designed to work on large construction sites. They are characterized by the following indicators:

• Operating weight – from 16.5 to 21.1 tons;
• Bucket capacity - 0,19-1,2 cubic meters;
• Boom length – from 2.52 to 2,71 meters;
• Capacity – from 90 to 122 kilowatts.

Each excavator "Hitachi" the price of which is reasonable equipped with hydraulic system HiosII that has established itself as a reliable and high performance. The power plant consists of a diesel Isuzu motor with a direct-fuel injection and water cooling.In Addition, the model distinguished by the presence of auto-locks the bridge and hold the brake and two-speed transmission and variable displacement axial piston pumps with variable flow.

Crawler excavators

Earthmoving equipment company caterpillar presented in two series-the ZX-3 and EX-6. Typically, the crawler excavator ZX-3 has a mass in the range from 1 to 85 tons. They are used in construction works and mining. Representatives of the lineup of EX-6 features a larger operating weights (from 114 to 811 tons) and are used in quarries and during Stripping operations.Model crawler have better permeability and resistance to weather and climatic conditions. Operating temperature range is from -50 to +45^O. There are instances that are designed to work with rocky and hard rocks, demolition of structures and operation in remote places. Each crawler excavator can be equipped with a shortened boom and increased in volume bucket if you need to withdraw a large amount of ground in a short period of time.

Marking crawler excavators

The working characteristics of the excavator "Hitachi" of the crawler depends on the installed hardware. Learn the features of the machine can be labeling:

• LC – models withthe engine of the increased length, are used on soft ground.
• LD – diggers "shovel" is intended for the development of soil above the point of support.
• N – copies to work with and heavy rock.
• K – modifications for carrying out the dismantling works, are equipped with attachments.
• MT – models with high traffic to work on the "cluttered" territory.
• USR, US and U – the representatives with a short, small and “zero” radius of the turntable.

Such a wide range of equipment allows each customer to choose exactly the model that will be needed to perform specific tasks.

Famous representative – Hitachi ZX 330

The Most popular crawler models, the company is excavator “Hitachi 330”, which is power. Despite the fact that the instance belongs to the middle class of technology, it competes with heavy excavators. It helps a reinforced boom design and steps, whereby increased safety and productivity. You realize the magnificence of the techniques, examining the technical characteristics. - Integrated automated functions and workflows has increased the functionality of the machine – it is suitable for any ground and for use in difficult conditions.

One of the few disadvantages possessed by excavator “Hitachi 330” is the speed. She is only 5.5 km/h. Therefore, for the transport to the place of excavation requires a special truck. The cost of such equipment is in the range of 7 million rubles.

Service equipment

For reliable and smooth operation of excavators "Hitachi" need high-quality and timely maintenance. Should be carried out periodically elektrosistem diagnosis techniques, inspection of hydraulic cylinders, Troubleshooting the major components and assemblies.

When fault detection is required urgently to replace a defective element. The benefit of the Japanese technique in the public domain are parts. "Hitachi" - excavators that will serve you faithfully for decades, if you will preserve them.
