designed for picking, carrying and loading reinforced concrete or stone blocks, beams, etc. objects weighing up to 1.5 tons and up to 4 tons, which corresponds to the maximum and minimum reach of working equipment.

The grab is installed on the EO-5126 excavator instead of a bucket, using standard axles and fasteners, without modifications or hydraulics.

The grab is made of two jaws, with the lower jaw having three teeth and the upper jaw having two teeth.

To ensure the functioning of the grab as part of the excavator, it is also necessary to install a support rod and bracket, and to ensure safe operation it is necessary to install a protective grille on the excavator cabin.

The support rod is connected at one end to the lower jaw of the grab, and at the other to the bracket, which is welded to the handle.

FSUE PA UVZ is preparing to release new modifications of the EO-5126 crawler excavator to the market.

EO-5126 are equipped with a pre-start engine heater “HYDRONIC-35” from the German company Eberspächer and an automatic centralized lubrication system from the German company LINCOLN. These innovations will be installed on EO-5126 excavators at the request of consumers.

This is another step by the enterprise towards improving the EO-5126 excavator, which is always popular with consumers and is currently the most popular model of Russian-made crawler hydraulic excavators on the domestic market.

The main advantage of the pre-start liquid heater “HYDRONIC-35” compared to the standard one is the presence of an electronic timer for programming the heater to turn on at the right time.

The advantages of using an automated lubrication system based on LINCOLN equipment are as follows:

lack of influence of the human factor on the lubrication process;
reduction in costs for repairs, spare parts and lubricants;
longer duration of trouble-free operation of equipment;
reducing the number of costly repair and maintenance interruptions;
longer intervals between maintenance;
radical reduction in the number of bearing failures caused by the lubrication process;
increasing the productivity of equipment by reducing its downtime, which helps to obtain higher profits.

EO-5126 excavators, equipped with the LINCOLN system and the HYDRONIC-35 engine preheater, were successfully tested in the harsh winter of 2006.

Design and research developments on the use of ACSS and pre-heaters of the HYDRONIC-35 engine on the products of FSUE PA Uralvagonzavod will be continued. In particular, in the near future it is planned to install an automatic centralized lubrication system on wheeled EO - 33211A and utility EO - 33211AK excavators.

About the manufacturer

Uralvagonzavod became one of the high-impact construction projects of the first Soviet five-year plans. The plant in Nizhny Tagil was built in 1931-1936 and was named after Felix Dzerzhinsky. At the beginning of the Great Patriotic War, tank plant No. 18Z named after the Comintern was founded on the basis of Uralvagonzavod and enterprises of the European part of the USSR evacuated to the Urals. Until the end of the war, he produced more than 25 thousand T-Z4 tanks. Every second tank that took part in the battles was made in Nizhny Tagil. Uralvagonzavod also produced armored hulls for Il-2 attack aircraft and artillery limbers.

Tank specialization, along with railway specialization, was retained by Uralvagonzavod in times of peace. T-54, T-55, T-62, T-72 and their modifications - they were all produced here. Currently, the main products of Uralvagonzavod are freight cars, tanks, T-90, and T-14 battle tanks, a modernized version of the T-72 tank; infantry fighting vehicles, fire support, mine clearance, bridge building. The enterprise plays an important role in domestic exports to the world arms market. The plans include establishing the production of modern trams and high-speed trains.

From 2000 to 2010, the company was engaged in the production of both tracked (23-ton) and wheeled (19-ton) universal excavators. At most, 500 of them were produced per year. In 2016, Uralvagonzavod again returned to the production of earth-moving equipment. The first excavators produced after a six-year break were the tracked EO-41211A with a new YaM3-5Z4 diesel engine and Korean-made hydraulics and the wheeled EO-ZZ222A, with similar aggregate equipment.

For the product line of new Tagil excavators, an improved operator cabin was developed, more spacious and comfortable for work, more ergonomically designed, equipped with a comfortable sprung seat. Sales and maintenance of all excavator equipment produced by Uralvagonzavod was organized through the ChT3-Uraltrak dealer network.

Device

Special rigid tracked equipment is produced in two assemblies for different climatic conditions: “standard” (works at high sub-zero temperatures) and “tropical” (up to plus fifty degrees in the tropics). Each design consists of three parts:

Platform with two motors for rotating function . There is also a spacious and modern driver’s cabin with a panoramic view; the glass is straight; if necessary, it can be easily and inexpensively replaced over time. Comfortable workplace, heater with front window defogger function, two windshield wipers, fan and sun visor;
Crawler bogie , consisting of a welded frame and tension wheels, 14 road wheels and 4 support rollers, two track drives and track belts;
equipment and accessories.

The standard kit includes a three-teeth bucket with a capacity of 1.5 cubic meters, a monoblock boom, a backhoe handle and a ripper that can be installed in place of the bucket. It is possible, at the request of the customer, to supplement with replaceable working bodies:

Buckets of different volumes, from 0.8 to 1.8 cubic meters, for certain jobs: narrow for digging trenches; reinforced; for bulk materials; changeling.

Advantages and disadvantages

A durable modern unit with a powerful motor and high cross-country ability. With automatic control system and alarm. The design provides access to any element, which allows repairs to be made on site or in any, even non-specialized service. Russian equipment significantly reduces maintenance costs. There is one drawback - a tracked vehicle is less maneuverable than a wheeled vehicle. For small areas it is not suitable for turning, but this is easily compensated by good stability; for large slopes and in conditions of weak-bearing soils, it is an indispensable unit. EO 5120 photos, prices and descriptions on the Internet are always an extensive base. You just need to study everything, analyze the market and make the right decision.

A little about pricing policy

Absolutely all new models are assembled only to order. The price will vary depending on the configuration and the presence of various additional design elements, etc.

The manufacturer does not openly say anything about the cost of EO-5126. You can find out only by individual request, for example, by phone. Therefore, we can only judge by the price of a used version, which starts from 600 thousand rubles. This gives every reason to believe that a new one will cost approximately 1.5-2 million rubles, however, it should be emphasized that this figure is approximate.

"Standard"

The “standard” version of the EO-5126 excavator is designed to work in the widest temperature ranges, in northern conditions with frosts down to -40?C, and in regions with heat up to +40?C. For such conditions, all-season oil can be used.

"Tropical"

For work in climatic conditions with high temperatures, up to +55? C, the “tropical” version of the excavator is designed.

Prices for new and used excavators

Today, new equipment assembled in 2002-2004 will cost about 900,000 rubles; those produced in 2008-2010, approximately, from two million to two million; for a new one you can pay three and a half or four million rubles. The difference depends on the sales region, year of manufacture and assembly. The price of used equipment will also depend on the operating time. Well-known Russian provides technical support for the entire warranty period. Taking into account all the requirements and innovations, the research and production corporation constantly updates and improves its products. The EO 5126 excavator was no exception - special equipment at the level of world standards.

The EO 5126 excavator is special equipment at the level of world standards.

Purpose

The EO-5126 crawler excavator is a multifunctional piece of equipment. It is often used by construction organizations, large industrial sectors, and mining industries.

The equipment can cope with such types of work as digging trenches and foundation pits; creation of embankments of soil and other bulk materials; cleaning work areas from industrial waste; loading and unloading various materials; excavation; quarrying; loosening frozen soil and rocks; compaction of loose soils; destruction of various concrete or reinforced concrete structures; digging canals and many other similar tasks.

It is worth noting that this excavator has the first, second, third and fourth categories of soil density in terms of strength, but to work with the fourth category, preliminary loosening is required. This action should also be performed if you are working with rocks and minerals. The maximum size of pieces of loosened rock should not exceed 500 millimeters.

The excavator can also be used on sticky soils and swampy areas, since the manufacturer offers wider caterpillar tracks specifically for this purpose.

Special equipment is available for sale in two assemblies:

"Standard". Operating temperature range -40°C/+40°C, copes well with cold climates.
"Tropical". Operating temperature range -20°C - +55°C, suitable for working in tropical climates.

Each assembly consists of 3 main parts:

Rotating platform with hood and mechanisms. It contains:

engine;
swing drive;
hydraulic equipment (pipelines, etc.)
driver's cabin (it contains the control system for special equipment);

Crawler trolley;
Working equipment;

The excavator chassis consists of:

welded frame;
caterpillar tracks;
two track drives;
wheels with surrender function;
swivel support (attached to frame):
skating rinks;

The standard equipment of the excavator includes 2 batteries, a generator, a starter, as well as signaling devices common to special equipment:

It should be noted that the automatic control system works like a clock and instantly signals any deviations from the norm. Considering the standard package, you can notice many advantages, such as:

Adaptation to harsh Russian winters.
Adaptability to work in conditions of high humidity and temperature (“tropical” assembly).
A comfortable cabin with a wide view, a heater with a front window blower function.
Components manufactured in Russian factories. This reduces maintenance costs.
Durability and reliability. The boom, frame and handle of the excavator are made of alloy steel with a strength class of 390.

The EO-5126 excavator was developed on the basis of the design bureaus of the Ministry of Defense, therefore it is balanced in characteristics, reliable and can withstand extreme use.

Other important indicators

The weight of the EO-5126 excavator is 32 tons.
Length/Width/Height for 600mm track model: 10.4/3.17/3.1 m
Length/Width/Height for 900mm track model: 10.4/3.47/3.1 m

As you know, the operating conditions of such special equipment can be very diverse. Working with soils in the far north with temperatures below -30 C can be fraught with breakdowns of some important components if the excavator was not designed for this. That is why the manufacturer released two different modifications of EO-5126: “Standard” and “Tropical”.

Both models have identical appearance, dimensions, and so on. However, the first one works at temperatures of -40°C - +40°C and can easily withstand harsh Russian winters. The second option is intended for use in warmer areas. Its operating temperature range is slightly different -20°C - +55°C. The name “Tropical” was not given to this variation by chance. Field tests have shown that the excavator really copes well with tropical climates, and its most important components are subject to wear in such conditions, no more than in ordinary ones.

What's included in each package:

1. Rotating part (platform). It has many important components installed, including the engine, hydraulic drive equipment, and the driver’s cabin. 2. Crawler 3. Additional work equipment

Among other things, the basic kit includes 2 batteries, a starter and a generator. On top of that, there are various sensors and indicators for temperature, fuel, pressure, and so on.

The EO-5126 excavator showed excellent performance in field tests. Particularly noteworthy is the operation of the automatic control system. At the slightest change or deviation from the norm, the alarm went off instantly and did not give any false information.
