EO 4121 technical specifications. Technical and technological characteristics of single-bucket hydraulic crawler excavators

The EO-4112A excavator (dragline) is intended for excavation work in light and heavy soils of categories I-IV. The excavator can be equipped with various types of replaceable equipment and perform the following types of work: - dragline - digging canals, trenches, loading soil into vehicles and dumps, using it for reclamation work; — backhoe – loading into vehicles, digging canals, pits, trenches, etc.; — with a straight shovel – quarrying, loading soil into vehicles and dumps; — with a grab – loading and unloading bulk materials, digging pits, wells, etc.

Definition and purpose

An excavator is a machine for digging soil. The working body is a bucket. It can be of different designs. To expand functionality, replaceable equipment is used: crane (hook), hydraulic hammer, pile driver, etc. In addition to the “classic” equipment, there are backhoe loaders and mini-excavators. According to the principle of operation, excavators are divided into the following types:

• Cyclic (cyclic action). This includes single-bucket machines.
• Continuous action. This group includes: multi-bucket rotary, with a front cutter, trench with a toothed chain.
• Vacuum.

Below we consider only the first category - an excavator with a bucket. By purpose, the following classification is adopted:

• Construction. Bucket volume up to 3 m3. They are mainly used for excavation or loading and unloading work. Most models are universal (that is, they have 4 or more types of interchangeable equipment).
• Career. They are equipped with working equipment from 2 m3 to 8 m3. They are used in quarries for the development of rock, coal or ore deposits.
• Overburden. Bucket capacity from 6 m3. They are used when it is necessary to remove (open) the top layer of rock, under which useful minerals lie. A distinctive feature is an elongated boom and greater power.

Special equipment is included in a separate group. This includes peat, destructive, tunnel, rescue, underground, railway, underwater, swamp and other models. They require special equipment and attachments.

General characteristics of dragline EO-4112

The main thing is to carry out technical inspections and scheduled maintenance in a timely manner. Distinctive characteristics also include fairly simple operation of the excavator. Drawing conclusions, it can be noted that buying the EO-4112 model means providing yourself with high-quality special equipment for a long time.

Control Features

A crawler dragline consists of a bogie, a cabin and a working body. The trolley, in turn, consists of a bent profile and a cast running frame. Tracks are made up of links that are attached to a track chain. The operator's cabin is characterized by a high level of thermal insulation. The cabin of the Hyundai R210LC-7 excavator also features comfortable conditions. It is located on rubber shock absorbers. Thanks to this, the excavator operator can spend a long time in the cabin and perform work without losing productivity. A comfortable anti-vibration chair reduces stress on your posture. For comfort, a fan and heating unit are also installed in the cabin. This allows you to control and create the required temperature in the cabin at any time of the year.

Electro-pneumatic control of working bodies makes it possible to quickly switch from one operation to another.

Before starting work for the first time, you should undergo safety training. If malfunctions or various problems occur in the operation of the dragline, it is worth carrying out an inspection or sending the equipment to a specialized center for repair work. If you have your own mechanics, then repair work can be done at home. Spare parts and necessary consumables can be easily purchased in specialized stores.

History of creation

The debut copy of this earth-moving equipment was assembled in 1970. After passing comprehensive tests, serial production of EO-4121 excavators was launched in 1974 at the Kovrov Excavator Plant, Vladimir Region.

Kovrovsky Excavator is the manufacturer of the first excavator in our country and, in general, one of the oldest enterprises in the entire domestic mechanical engineering industry. It was founded on the production base of railway workshops operating since 1861 at the Kovrov station of the Moscow-Nizhny Novgorod railway.

In 1930, the workshops were transformed into a plant for the repair of foreign-made earth-moving machines. And already on April 21, 1931, the first Soviet excavator in history was built here, which became the ancestor of the extensive family of Kovrovets excavators.

Both in Soviet times and to this day, the Kovrov Excavator Plant is one of the most advanced and leading domestic enterprises in this industry. Over the years of operation, about one hundred thousand units of earth-moving equipment rolled off its assembly line, and the number of different models and modifications reached 64 types. The EO-4121 excavator lasted on the factory assembly line until 1991, and its direct “descendants” were the EO-4124, EO-4125, EO-4224, MTP-71 (“EO-71”) models. 4221"). The modern embodiment of the EO-4121 concept can be called the EO-4225 excavator - a more progressive and advanced version.

Today Excavatorny specializes in the production of full-rotary hydraulic crawler excavators: “KiT-26”, “EO-4225A-071”, “EO-4225A-061” with a full range of attachments. It also produces forestry and loading equipment.

Options for purchasing the EO-4112 model

The price for the EO-4112 excavator can be completely different. For used models of earlier years of production, the cost will be within 800,000 rubles. As for models that were produced in a later period and are characterized by minimal mileage and excellent technical condition, the cost can increase up to 3 million rubles. The purchase of this equipment is justified by its technical indicators and high performance in different conditions. If you need to perform one-time work, then it is more advisable to rent equipment for a certain period of time. The cost of renting the EO-4112 model today will vary within 12,000 rubles for an 8-hour working day. Costs may increase when transporting equipment to the job site. Knowing all the prices, you can determine which option is best suited in a particular case.

A comparative analysis of the technical characteristics of excavators shows that the EO-4112 A-1 excavator, having lower ground pressure and higher travel speed, is much more maneuverable. Due to lower fuel consumption, better transportability is ensured.

Experience in operating excavators shows that the EO-4112A-1 excavator's annual soil production is 10-12% greater than that of the EO-5116-1 excavator. The presence of a torque converter in the EO-5116-1 excavator entails additional costs for hydraulic oil and, as a result, the excavator requires higher operating costs.

In addition, the low-speed diesel engine installed on the EO-4112A-1 excavator has a longer service life compared to the high-speed diesel engine installed on the EO-5116-1 excavator.

Specifications table

The technical characteristics of excavators are scattered over a very wide range. This is due to the fact that the machines have different purposes and are designed for different volumes of work. The main technical characteristics are summarized in the table:

The volume of the bucket is given geometrically. The actual amount of soil removed during operation, due to the “cap”, is 15-30% higher. On machines that are planned to be used on heavy soils, buckets of a smaller volume than necessary for this group are installed.

In addition to the parameters indicated in the table, the performance of an excavator depends on its design and technical condition. And also on factors not directly related to the unit: proper organization of work, driver qualifications, soil density, etc.

Engine

The EO-4121 excavators were equipped with diesel engines of the A-01 and A-01M brands from the Altai Motor Plant, Barnaul. It is simple in design and maintenance, unpretentious, high-quality motor, which is still produced and installed on a number of agricultural, industrial and forestry tractors, and on road construction equipment.

A six-cylinder four-stroke naturally aspirated diesel engine of type “A-01” is equipped with a two-valve gas distribution mechanism on each cylinder. The arrangement of the cylinders is in-line, vertical. The mixture formation method is direct fuel injection. Cooling method – liquid.

Engine A-01

In the design of the motor, special cast iron liners were used, with the working surface treated by flat-top honing; pistons with a three-ring set of piston rings, optimized side surface profile and graphitized skirt; crankcase with increased strength and improved cooling of cylinder liners. The engine has a solid service life (up to 12,000 operating hours).

• Cylinder displacement: 11.15 l;
• Rated power: 99 kW, or 135 hp;
• Cylinder operating order: 1-5-3-6-2-4;
• Cylinder diameter: 130 mm;
• Piston stroke: 140 mm;
• Compression ratio: 16.5 (+/- 0.5);
• Rated crankshaft rotation speed – 1700 rpm;
• Nominal torque reserve factor – 25%;
• Specific effective fuel consumption at rated power – 221 g/kWh (163 g/hp-h);
• The relative oil consumption for waste is 0.3% of fuel consumption.

The A-01 engine drives two hydraulic pumps with adjustable output. Both pumps are installed in the same housing and driven through a gearbox. Additionally, a pre-start heater “PZHB-300V” is installed, which makes it easier to start the engine in conditions of especially low temperatures.

Chassis

The chassis is a tracked mechanism in which each track receives force from an individual hydraulic motor through a gearbox. The hydraulic cylinder is responsible for tensioning the track. The design of the chassis is equipped with widened links, which can significantly reduce the pressure on the ground. This option is intended for use on waterlogged and weak soils.

The turning mechanism includes a three-stage gearbox, a rotary gear and a hydraulic motor, consisting of safety and distribution equipment, a double pump and executive working elements. The performance of pumps mounted in a single housing can be adjusted. They themselves are started by diesel engines through a transfer gearbox. On the turntable behind the cab there are spool distribution blocks.

The crawler trolley of the EO-4124 excavator is equipped with tracks made of cast tracks with lantern gears. Nowadays, such a solution is no longer used, or is used quite rarely. However, it provides excellent reliability and wear resistance of excavator tracks. As a rule, the service life of tracks of this design is two to three times longer compared to conventional tracks.

Hydraulic system

The hydraulic drive of the excavator includes: a double pump, distribution and safety equipment, executive working elements. Hydraulic pumps of adjustable capacity, mounted in a single housing, are driven by a diesel engine through a transfer gearbox. The spool distribution blocks are mounted on a turntable behind the cab. The pressure of the working fluid in the hydraulic circuit of the drive of the working parts of the excavator was ensured at the level of 250 kg/cm, which for those times was a record figure for both the Soviet Union and Europe.

Excavators EO

EO excavators are part of municipal construction equipment. The machines are used not only in the countries of the former USSR, but also abroad. EO excavators are suitable for municipal construction work due to their high efficiency and versatility. Now the machines are used not only by state enterprises - they are in the public domain. The model range is also valued by owners of construction companies for cheap repairs of EO excavators and a large selection of replacement parts. Production continues today - two types of EO excavators are rolling off the assembly lines of the largest factories (the main supplier-manufacturer of EO excavators is Ural-MASH):

• Tracked vehicles;
• Wheeled vehicles (in limited quantities).

Modifications

A total of two modified versions of this crawler excavator were produced, namely EO-4121A and EO-4121B. The most popular version of them was the second modification.

The EO-4121B differs from the basic excavator in having a reinforced boom, due to which the scope of application of the equipment has been expanded. The machine began to be used for quarrying and loosening rocks. In addition, this change allowed the excavator to work with very heavy weights, which is also a big plus.

EO-4121B

The machine can use a hydraulic breaker, pincer-type gripper, as well as loosening equipment in the working process. All this allows the equipment to carry out stripping work in frozen and rocky soils.

The operator's cabin is located on rubber shock absorbers, which absorb strong vibrations and shocks that occur during operation. The cabin also has an adjustable seat and transport air conditioning (installed optionally).
