What is a bar machine

A bar excavator is a loader-excavator with canopies, which is used for excavation work in large areas. The equipment can also be used for loading and unloading work on a construction site, in forestry or municipal areas. The main working part of the earthcutter consists of a bucket and a back bayonet shovel.

A soil cutter (bara) is a tractor to which a tool is attached that cuts the ground. Visually, the device resembles a huge chainsaw. This type of equipment first processes the desired area, and then removes the soil through an auger. This prevents soil from backfilling into the treated area.

Bar machines are usually mobile and compact; they consume little energy but have great productivity.

Purpose

Main purposes of the soil cutter:

  1. Quickly create narrow trenches where you can lay a pipeline or cable line.
  2. Development of hard soils. It is especially convenient to use this technique when you need to dig up frozen ground in winter.
  3. Removing old road surfaces.
  4. Loosening tough soils.
  5. Cutting limestones and sandstones.

The main advantage of the equipment is that it can be used in any climatic conditions. If workers cannot manually process the soil in winter, then they can do this without much difficulty using a special digging machine that has high cross-country ability and maneuverability.

Digging trenches with a bar

If you need to quickly and accurately dig a trench 0.2–0.4 m wide to a depth of 2 m, use a soil cutter. This is a more effective and less expensive solution. Renting a bar is much cheaper than renting an excavator. At the same time, the trencher easily copes with the development of frozen and particularly dense soils, including those where rocks, pieces of asphalt and concrete are found. Another advantage of the soil cutter is the ability to combine the digging process with cleaning the bottom of the trench, which after the excavator has to be done manually. The bara is mainly used for digging narrow trenches for laying electrical, telephone and fiber optic cables and pipes for various purposes.

You can order any excavation work on a turnkey basis and at the most affordable cost in Moscow and the region. Call the number to place an order or get a free consultation on choosing equipment for digging trenches.

Where are bar machines used?

Soil cutting machines are usually used in areas where it is necessary to quickly and accurately excavate a trench or lay various communication systems underground:

  1. Gas pipeline.
  2. Pipeline.
  3. Fiber optic networks.
  4. Water pipes.
  5. Sewerage.

But this is only part of the functionality of earthmoving machines. Bar machines are also used on construction sites, where it is necessary to prepare the work area for the construction of a building - to level the surface and remove excess debris from the site.

The services of soil cutters are often ordered by utility services if it is necessary to remove a certain block of land in order to replant trees or shrubs. A trencher is a useful multifunctional tool that greatly simplifies any type of soil processing work.

Advantages of using a soil cutter with a shovel or other support:

  1. The structure of the bar machine is designed in such a way that the cutting parts rotate at a very high speed. This allows you to create “clean” trenches in the shortest possible time.
  2. Since there is no need to remove soil from the treated area, you can immediately move on to the next stage of construction, which significantly saves time.
  3. If necessary, the unit can quickly remove the ice and move on to digging tasks.
  4. The treated soil will have smooth, non-crumbled edges.
  5. Possibility of using a soil cutter on different types of soil - from hard to unstable.

This will ensure the quality of the work performed.

Digging a trench: manually and with an excavator


Preparation for the construction of buildings and structures begins with excavation work. Here, one of the most important stages is the laying of trenches under the foundation and the installation of communications, which is preceded by design and soil analysis. The more carefully the preparatory work is completed, the fewer problems will arise during the construction process.

If you have to dig a trench, you also need to know which excavation method will be most effective in your case. You will also be interested in the cost of the work. Therefore, in this article we will also tell you how much it costs to dig a trench manually, using a mini excavator and a trencher bar.

Device of soil cutters

An industrial soil cutter consists of several main parts:

  1. The tractor to which the main working part is connected is the bar machine. The soil cutter weighs a lot, and therefore it is advisable to connect it with mobile special equipment, rather than carry it manually.
  2. Bulldozer blade. This part is of a rotating type, which improves backfilling of the trench if necessary after digging.
  3. The bar working body is precisely this part that is needed for digging.
  4. Hydraulic speed reducer. Designed to reduce the speed of the tractor when the bar mechanism is activated. To reduce the speed, a hydraulic speed reducer is installed on the tractor gearbox. After installation, the machine will not be able to reach speeds higher than 800 m per hour.

Thanks to this device, the soil cutter crushes and loosens the soil, and then carries it outside the created ditch.

Equipment equipment

Standard set of soil cutting machine:

  1. The main part is the bar organ.
  2. Guides where the chain is installed.
  3. An auger through which excess soil is thrown to the side during operation.
  4. A scraper used to finish a trench.
  5. Rotary blade.
  6. Wear-resistant blades for the blade.
  7. Speed ​​reducer.
  8. Front loader or tractor.
  9. Snow dump.
  10. Knives with carbide surfacing.
  11. A set of hoses through which the trencher is installed with the hydraulics of a loader or excavator.

If necessary, you can order additional equipment or spare parts from the manufacturer for more specific work. Universal trenchers are a mounted and replaceable tool for loaders that can be modified by ordering additional parts.

In addition to the described capabilities, with the correct configuration, it will be possible to configure the device for creating reclamation systems and drainage drains.

Soil processing becomes possible thanks to special teeth, which have several types. The differences are due to the strength and purpose of the work performed:

  • for working with soft soil, steel teeth are suitable;
  • if the soil is mixed, it is advisable to have not only steel samples, but also tungsten ones;

According to user reviews, tungsten teeth cope with cutting asphalt, ice and hard soil.

Types of soil cutters

Bar machines are divided into two types: by drive type and device size.

Depending on the type of drive used, you can additionally find on sale:

  1. A trencher powered by a hydraulic drive. Typically a JCB 3CX loader or excavator is used as a base.
  2. Bars connecting to the tractor shaft, through which there is a further connection to the engine of the bar machine. This is a mechanical type of device.
  3. The latter type is divided into subtypes - combined or electric drive. These devices are now rarely used.

Depending on the size, equipment is divided into heavy, medium and manual:

  • A manual machine is rarely used in industry - it is a unit for private property in rural areas.
  • Heavy series - equipment used in mining activities (stone-cutting mechanism).
  • The middle type is used in construction, laying roads and underground communications (ETS-1609, BGM-2U and similar models);

The most popular is the medium type of soil cutter.

Soil cutters based on MTZ

This type of machine is used in combination with various construction means, domestic and foreign. MTZ bar machines are most in demand for:

  • laying communications in a trench;
  • ice removal;
  • excavation;
  • demolition of old buildings.

The main advantage of the excavator (bar) at MTZ is mobility and practicality. These types of tractors have greater maneuverability and are lighter than tracked models. An additional advantage of the soil cutter is the ability to move on asphalt surfaces (without damaging the road layer) at speeds of up to 60 km/h.

Any type of domestically produced equipment based on MTZ is assembled in accordance with European standards and is adapted to operate in any weather, even rain and snow.

One of the most common types of equipment under consideration is a bar installation on MTZ 82 and ETC 2086.

  • Cutting width up to 300 mm
  • Trench depth up to 1.8 m
  • Minimum order: Eight hours

Manual soil cutters

Manual soil cutters are used when the trench width should be no more than 150 mm and the depth should be 50 mm. In construction, such equipment is used extremely rarely, since without a base in the form of a tractor or loader, the speed of work will be significantly reduced.

A manual soil cutter is usually used on private plots or farms, where you need to lay pipes on your own or create trenches for other purposes. Portable trenchers are called "ditchers" because they cannot handle the amount of work that can be done with industrial equipment.

For ease of movement, manufacturers equip the bar machine with two or three wheels (the number depends on the chosen model). In the catalogs of construction stores there are also tracked models, which are very popular when compared with wheeled units. Manual machines are not mounted on tractors, and therefore the operator must be behind the machine, turning the toggle switches that regulate the progress of the machine.

A mini trencher is relatively inexpensive and is capable of creating a trench up to 65 cm deep and 10-15 cm wide. Bar equipment is placed on a small platform. The higher the price of a soil cutter, the more opportunities there will be for use on a private plot. For more expensive types of equipment it will be possible to install additional canopies:

  • dump body;
  • concrete mixer;
  • chainsaw;
  • Boer.

When choosing a suitable soil cutter for your site, you need to know that foreign companies dominate the sale of manual equipment (a similar situation with walk-behind tractors). A domestic small-sized model will objectively be inferior in quality to foreign technology. The opposite situation is observed when choosing attachments for tractors or loaders - Russian manufacturers occupy the leading positions in quality and assembly.

Application of bar soil cutters in construction

The change in habitat and the versatility of the use of bar working bodies in construction had a detrimental effect on the unification of terminology. Thus, in textbooks and reference books on different types of equipment, machines with a bar organ are called differently: chain, trench excavator, scraper unit, asphalt cutter, ditch digger, soil cutter or bar machine .

The working body - the bar - consists of a guide frame and a cutting cam chain with teeth. Depending on the number of bars connecting the fists, one- or two-bar cutting chains are distinguished. If there are no bars and the knuckles are hinged, the chains are called barless. During operation, the bar moves in a vertical plane with the translational movement of the entire machine, as a result of which the soil is destroyed and carried by a chain to the surface. The soil brought to the surface is moved by a screw conveyor to the sides of the trench.

Bar soil cutting machines are used for cutting cracks in frozen and hard soils when digging trenches and pits; cutting narrow trenches (when working with one bar) intended for laying communication lines and electrical cables; works on cutting limestones and sandstones; cutting blocks around tree plantations during their winter replanting; destruction of frozen soil peaks.

The speed of excavating material from a trench using a specialized trench excavator can be six times faster than that of a conventional excavator. Moreover, a trench excavator removes just enough material to lay the pipeline, leaving the trench clean and ready for the final installation of pipes or cables. Finally, the material removed by such an excavator has a uniform particle size structure and can be used for backfill, whereas the material removed by a conventional excavator may contain large blocks that require additional destruction. These advantages provide high productivity, 4.5 times greater compared to traditional technology, and, accordingly, profitability of specialized trenchers where there is sufficient volume of work.

In construction, bar machines of various modifications are used, cutting 1. 3 slots with a width of 140. 500 mm and a depth of 1 to 6 m. The cutting speed, depending on the number of slots, cutting conditions and the strength of the soil or rock being mined, is 2. 1000 m/h. The most effective bar machines used in construction are those equipped with high-strength teeth and bar chains, as well as base machine creepers, pile ejectors, augers and other hydraulic control and drive systems. It must be taken into account that for different types of soil, bar canopies may differ in the design of the drive mechanisms. The chain drive is usually carried out from the tractor's hydraulic system or mechanically from the rear PTO of the base tractor. Electric and combined drives are extremely rarely used.

In total, 18 enterprises produce mounted bar equipment in the CIS countries: Amkodor-Udarnik, Belkommunmash, Dor-Elektromash, Navlinsky, Oktyabrsky, Gorlovsky and Okhtinsky construction machinery plants, Omsktransmash, Orelstroymash, VAT "Stroydormash" (formerly DP "Kiev Engineering Plant") machines to the Ministry of Machine Industry of Ukraine"), the Dmitrovsky Excavator Plant, the Kopeysky Machine-Building Plant, the Mikhnevsky Mechanical Repair Plant, the Zametchinsky Mechanical Plant, the Khmelnitsky Mechanical Plant, the Chelyabinsk and Lipetsk Tractor Plants and the Turbomotor Plant in Yekaterinburg. In addition, the Russian market includes American trench excavators Trencor, Ditch Witch, European Case and Vermeer and Estonian AS ET MOisakУla (PO Tallex).

Wheeled universal tractors "Belarus", ZTM, LTZ, YuMZ or mini skid-steer loaders of domestic and foreign production on caterpillar or pneumatic wheels are usually used as the base chassis for municipal services. For field and construction work with large volumes of work, the KhTZ T-150K chassis and the ChTZ, PTZ and VgTZ tracked tractors are most often used.

Currently, almost all foreign-made mini-loaders are equipped with bar working bodies - Bobcat, Case, Caterpillar, Gehl, JCB, Locust, New Holland, etc. Chain trenchers are installed as additional equipment on domestic skid steer loaders from Kurganmashzavod MKSM-800, Mosgormash KSM-1, Uralvagonzavod PUM-600 and PUM-1000. Belarusian mini-loaders are equipped with a chain mechanism only by Gomselmash (Polesie UES-30). The main advantage of using a bar working body on loaders is the ability to quickly change, the compactness of the equipment, the ability to work in hard-to-reach places and in limited space. The drive of the working body is carried out from the hydraulic system of the loader.

The basis of the bar trencher fleet in Russia is made up of machines based on wheeled tractors of traction classes 0.9 and 1.4 with bulldozer equipment. This popularity is explained by the prevalence of Belarus, LTZ, YuMZ and ZTM tractors in municipal and road construction and the presence of a sufficient material base. Ease of use, as well as high wear and tear of equipment on a wheeled tractor, can only be limited by the absence of a creeper and the inability to adjust the speed of movement of the cutting chain. A strong argument in favor of installing trenchers on wheeled tractors "Belarus-80" and -82 is the combination of cutting slits and loading and transport operations (the tractor must be equipped with loading equipment "Tallex" (MOisakУla), "Amkodor" or "Dorelektromash" ).

When combining road and utility work, a DEM-10035 bunker harvesting machine can be installed on MTZ tractors. In order to expand the functionality for tractors from the Chelyabinsk, Minsk and Volgograd tractor plants, the Mikhnevsky Mechanical Repair Plant offers trenchers with two cutting bodies. Dorelektromash, MОisakУla and Case also install a disk asphalt cutter in addition to the bar working tool. Since 2003, Orelstroymash has been offering for installation the hydraulically driven BGM-3U-60 with a chain scraper working body and a chain body with carbide plates. Kiev VAT “Stroydormash” is installing an MRMG installation with a bar cutting chain from a Ural-33 shear mining machine on HTZ T-150K tractors.

Digging trenches with a mini excavator

Small-sized special equipment allows you to mechanize excavation work on medium- and large-sized objects. Digging a trench with a mini-excavator is an effective solution on land plots that require soil excavation up to 2.5 m deep with a channel width of 0.3 m. In addition, the use of special equipment optimizes the timing of the work, ensuring high quality and accuracy of digging, as well as possibility of quick backfilling after installation of formwork, laying pipes or cables.

Cost of digging with a mini excavator

The price of mechanized trench digging depends on the amount of work. The minimum cost will be 20,000 rubles. It includes an 8-hour shift of an excavator (12,000 rubles) and its delivery to the site (8,000 rubles). However, this is significantly less than the cost of digging trenches by hand.

In 8 hours, a mini-excavator digs up 60 m 3 of soil. This is 150 linear meters of a trench 1 m deep and 0.4 m wide. Thus, the cost of 1 m 3 of developing a land plot using a mechanized method is 300 rubles. This is 2.5 times cheaper than the minimum prices for excavators - 800 rubles per 1 m3, which increase depending on weather conditions. With a larger volume of work, the price per trench becomes even lower: you pay for delivery once, and it can work in three shifts.

Bar soil cutters

In the history of technology, it is extremely rare for types of equipment to change their “registration”. Soil cutting machines are an exception. Bar working bodies were originally used in mining on cutting machines at the end of the 19th century. In the practice of earthworks, from the end of the 19th century, bar machines began to be used in the construction of railways. Bars, the working parts of cutting machines, began to be mounted on tractors and self-propelled tracked chassis. Later, these machines found wide application in public utilities and construction for cutting trenches when laying pipelines, cables and other engineering structures. At the same time, the use of shearing machines in mining decreased.

The change in habitat and the versatility of the use of bar working bodies in construction had a detrimental effect on the unification of terminology. Thus, in textbooks and reference books on different types of equipment, machines with a bar organ are called differently: chain, trench excavator, scraper unit, asphalt cutter, ditch digger, soil cutter or bar machine.

What is a bar machine

Before studying the technical characteristics of the bar installation on the MTZ 82, as well as other models of attachments for tractors, you should familiarize yourself with this type of device in more detail. Products of this kind are a kind of earth-moving unit, placed on the basis of tractors and some other types of special equipment.

The main working element of such installations is the bar chain for Ural 33 and other models, which is used for processing soil and rocks. Another more popular name among specialists for such devices is a soil cutter, for example, a bar soil cutting machine BGM 1. The design and technical characteristics of a particular unit depend on the model and its manufacturer.

It must be taken into account that today there are several types of construction equipment in this category on the market. Among them it is worth mentioning:

  • bar installation on MTZ 82 and other models;
  • devices on tractors DT-75%
  • installations on tractor equipment T-130, 170, T-10 and B-10;
  • chain excavators;
  • separate soil cutting machines.

Having found out what trenchers are, it should be noted that each of the varieties has different operating parameters, as well as advantages, disadvantages and features that should be taken into account during operation. Repair of such products, as a rule, does not cause problems, which is due to the simple design of the working elements.

Machines in mining

For the first time, units of this kind began to be widely used in mining - the first cutters used in mining operated using a chain drive. The device was first developed by Scottish engineers and later refined by American specialists. Among domestic users, the Victoria bar stone-cutting machine is most widely used.

Modern chainsaws and bar digging machines operate on a similar principle, since the equipment uses an endless cutting chain element placed in the grooves of a special frame. The design and the presence of additional elements - cutters, teeth, blades directly depend on the purpose of the unit.

Excavation machines

Despite the fact that the products were first used for mining operations, today they are widely used in the construction of various structures, as well as in the public sector. Such units are called soil cutters and trenchers.

There are 3 main types of them:

  • portable units, for example, manual mini installation;
  • medium/compact devices;
  • heavy installations.

The latter are used relatively rarely, since they are used to form large trenches. The use of the first two groups is widespread due to their mobility and efficiency. They are used to create small trenches with the release of crushed soil to the surface.

Most often, consumers are interested in renting such devices, since a bar stone-cutting machine requires a significant investment for purchase, and its scope of application is small.

Digging trenches by hand

The oldest, most labor-intensive, time-consuming and ineffective way to develop trenches. The cost of manual labor is high, and the speed of work directly depends on the condition of the soil. However, it is still used today - where there is no other opportunity to make a narrow excavation or when the use of equipment is not economically justified. But even in this case, the work should be entrusted to professionals who know the requirements of SNiP and RD. Otherwise, utility lines running through the site may be damaged.

Cost of digging manually: price per 1 m 3

Working conditionsPrice
At a depth of 0.75 mFrom 500 rub./m 3
In conditions of soil freezing by 1.5 mFrom 1000 rub./m 3

Manual trenching has one advantage: it is more efficient when digging through hard and heterogeneous soils. In addition, this method allows you to perform work more accurately and accurately. The disadvantages of the method include factors that determine the price per linear meter:

  • design trench depth;
  • characteristics and current state of the soil;
  • season;
  • weather;
  • building density;
  • the presence of previously laid communications at the site;

All this affects the increase in the cost of work. Therefore, manual trench development is an extreme measure, which is resorted to when it is impossible to use more economical solutions using high-performance special equipment.

Setting up bar installations

When studying the design of these devices in more detail, it is advisable to first consider the main working body. Its device allows you to simultaneously cut, grind the soil and move it to the side, avoiding shedding into the resulting trench.

Considering the design of the ETC bar installation and others, it should be noted that the devices differ significantly from each other in the type of drive of the working unit, since it can be either mechanical or hydraulic. Some less common models may use combined or electric operating units.

In order to increase operating efficiency, as well as synchronize equipment, creepers are widely used together with bar installations. The units are indispensable when laying trenches for various cables, pipes and other types of communications.

Equipment

The equipment of this kind of machines directly depends on the equipment manufacturer. They are a tractor on which bar attachments are installed. In this case, the equipment may include the following devices:

  • front loader;
  • rotary blade, including one equipped with hydraulic skewing;
  • mounted forklift.

The use of additional equipment can significantly expand the functionality of the units , making their operation more convenient and efficient. However, it should be remembered that if the client is interested in renting a bar installation, its cost will increase not only in proportion to the condition of the device, but also to the presence of additional elements.

Rent a trencher (bars) in the Moscow region, Moscow and the region

A short guide to renting trenchers in the Moscow region, Moscow and the region

What you need to know to rent a trencher

Trencher (ground cutter, bara) is a motorized equipment for digging trenches for communications. The different designs of trenchers differ in characteristics and areas of application: trench excavators, mounted bar installations or manual trenchers (mini-trenchers).

Based on the type of design of the main working body, trenchers are divided into chain cutters (the most popular), disk cutters and multi-bucket cutters.

How to avoid work disruption

Make sure that the work site does not cross the routes of any communications (cables, pipes). If necessary, obtain permission for excavation work. Remember that the customer of the work bears responsibility for damage to communications.

To avoid disruption of work due to a breakdown of the bar installation, conduct a soil analysis at the work site before ordering bars. Usually, for this purpose, soil samples are taken in several places at the site of the upcoming work (with an excavator or shovels) to make sure that there are no hidden hard rocks, reinforcement, or concrete structures that could break the chain and other trencher units.

Discuss in advance and describe in the rental agreement how you will act if, after delivery of the equipment, it turns out that the quality of the soil will not allow the bar to work or its use will lead to a breakdown:

  • who will remove the equipment?
  • will there be penalties
  • At whose expense will repairs be made in the event of a breakdown?

How to choose the best offer for renting trenchers in the Moscow region, Moscow and the region
