EO-5126 "Tagil" is a multi-purpose tracked single-bucket hydraulic excavator with a rotating platform and rigid suspension of working equipment. Products of the Research and Production Corporation "Uralvagonzavod", Nizhny Tagil. This special equipment is used for the development of unfrozen soils of categories 1-4 - for the development of trenches and pits, with pieces no more than 500 mm in size. It can also be used on frozen and rocky soils, after they have been previously loosened. EO-5126 was also produced at the Voronezh Excavator Plant, which finally ceased to exist in 2OO9.
This excavator model is available in two versions: standard, adapted for use in cold climates (full temperature range: −4О°C ... +4О°C), and tropical – for work in hot climates (full temperature range: −2О° C … +55°C). It was completely developed by Uralvagonzavod specialists and is produced at the enterprises of this large state corporation.
The E0-5126 excavator meets the current criteria for the structural reliability of special equipment, and the traditional quality of Uralvagonzavod and the impressive safety margin of all its components and mechanisms are guaranteed by a certified production quality system. Access to the main components of the excavator is convenient, the design is thought out in such a way that it is possible to carry out maintenance and repair of the special vehicle without problems in any, including non-specialized, workshops.
The manufacturer provides an 18-month warranty for E0-5126 excavators (or 1.5 thousand operating hours, whichever comes first); provides comprehensive service technical support for this equipment both within the warranty period and after its expiration. This is designed to ensure the longest possible operating time of the excavator and reduce the cost of its maintenance and repair.
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 released after a six-year break were the tracked 1A with a new Korean-made diesel engine and hydraulics and the wheeled 2A, 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.
The EO-5126 excavator consists of three main parts: a rotating platform with mechanisms and hoods; crawler trolley; working equipment. The rotating platform of the EO-5126 excavator houses its engine; hydraulic pump drive; rotary drive; pipelines and other elements of hydraulic equipment. At the front left, on the EO-5126 rotating platform, there is a driver’s cabin, in which all the excavator controls are located.

Review of the EO-41211 excavator produced by OJSC UKBTM, Nizhny Tagil.
Technical characteristics of the EO-41211 excavator:
| Excavator weight | 23000 kg |
| Engine power | 135 kW |
| Excavator speed | up to 4 km/h |
| Main bucket capacity | 0.85 cubic meters (5 teeth) |
| Capacity of replaceable buckets | 0.42; 0.95; 1.05 cubic meters |
| Digging depth | up to 7400 mm |
| Unloading height | up to 7300 mm |
| Digging radius | up to 10400 mm |
| Overcome angle of climb | up to 30 degrees |
| Excavation angle | up to 5 degrees |
| Cycle time | 18 sec |
| Estimated performance | 170 cubic meters/h |
| Working pressure in the hydraulic system | up to 36 MPa |
| Bucket cutting force | 15000 kg |
| Handle cutting force | 15001 kg |
| Resource | not less than 10000 h |
The new EO-41211 excavator is equipped with a DEUTZ BF6L2012C engine with a turbine, this is already a big plus; previous machines had YaMZ-238 engines on the EO-5126 crawler excavator, and YaMZ-236 on the EO-33211 wheeled excavator.
Of course, DEUTZ is a world name in engine building, and these engines are installed on a huge number of vehicles, ranging from small Chinese-made trucks to shipbuilding.
The DEUTZ BF6L2012C engine has the following parameters:
| Working volume, cm3 | 6057 |
| Power, kW/hp at 2000 rpm according to ISO 3046 IFN | 125/170 |
| Specific fuel consumption, g/kWh | 214 |
In the future there will also be configurations with a YaMZ-534 engine with a power of 135 kW, and of course with a turbine.
Refill containers:
| Cooling system, l | 24 |
| Engine crankcase, l | 14 |
| Fuel tank, l | 370 |
The cabin has a completely different shape, more reminiscent of a Hitachi cabin; the manufacturer claims that it is made of a metal frame for maximum structural rigidity and operator safety.
There was more comfort, a standard radio and an OS-7-U2-24 heater from the Murom Climate Equipment Plant appeared. The seat has become much more comfortable, the instrument panel has changed. However, the hydraulic controls remain the same.
Hydraulic control joysticks and pedals are manufactured by Pnevmostroymashina OJSC, as on their predecessors.
The hydraulics as a whole have undergone changes; the pump unit and hydraulic motors for travel and rotation are installed from the Bosch Rexroth brand; Voronezh predecessors such as EO-5225 and VEKS 30L were equipped with similar ones.
Hydraulic filter elements were also replaced with imported ones, “Sofima”. The manufacturer does not specify the brand of hydraulic units; perhaps they were also inherited from previous EO-5126 models.
The excavator is also equipped with a “Hydronic-M12” pre-heater with a timer, which greatly facilitates engine starting at low ambient temperatures. It is simply necessary for our country.
The chassis has undergone changes, but not completely. The guide wheels remained the same, as on the EO-5126, and on the earlier Voronezh models. The tracks, support rollers and sprockets were also inherited from the predecessor EO-5126.
The track rollers look different, and there is also no mechanism for tensioning the track chain.
The attachments, judging by the standard bucket with the basic configuration, have not undergone any changes; the crowns and adapters of the bucket are very similar to those from the EO-33211 excavator, as is the design of the bucket itself, as well as the rods and levers of the bucket.
The following types of attachments can be used:
- hydraulic hammer
- pneumatic hammer
- grab grip
- bucket leveler
- grab digging
- bucket 0.85 m3 (standard)
- upside-down bucket
- ripper
- bucket 1.05 m3 (for bulk materials)
- bucket 0.42 m3 (trench)
41211 will also be produced as a tractor, as evidenced by numerous photos on the Internet.
From 2020, UVZ planned to produce 50 of these excavators per year, but information on prices and sales could not be found on the Internet, only pre-orders, which did not indicate delivery times and forms of payment.
Technical characteristics of EO-5126
For its size and standard equipment, the excavator has quite good characteristics. The kinematic digging depth is up to 6 m, and the working radius is 9.5 m. The equipment is capable of unloading to a height of about 5.8 m. At the same time, the pressure on the supporting surface (very important when digging trenches so that the excavator does not push through the walls) varies from thickness of the model tracks. If this is an option with 600 mm tracks, then the pressure is 70 MPa, and if it is 900 mm, then 46 MPa.
An experienced driver completes a work cycle in 20 seconds. The digging force is approximately 175 kN. The rotating platform is capable of making up to 10 full revolutions per minute. The standard model has a bucket with a total capacity of 1.4 m3, however, depending on the version, the figure may vary, although not very significantly.
