Modern construction is no longer without earthmoving machinery. One of them is a manual trencher. In a short time, with its help you can dig a trench in the soil of any hardness. Engineering communications, power supply systems, communication cables and pipelines are laid there.
This technique is rarely purchased by private consumers, because it is quite expensive. You can familiarize yourself with the assortment of such products and understand that even the minimum cost for many can be unbearable. Therefore, before making a purchase, you must evaluate how often you will use the device, as well as what tasks you plan to set for them.
If the equipment will be operated once during the construction of a country house and the construction of the bath, then it is more advisable to consider the possibility of renting. This approach is also good because you will pay not only the cost of renting the equipment, but also the services of a professional who in a short time will dig a trench according to your size.
Description
Manual trencher is a design on a tracked or wheeled chassis. This ensures excellent soil grip and stability, which is true even on uneven surfaces. As one of the important nodes is the cutting unit. It has the appearance of a solid frame and a cutting chain with a sprocket of tension. Additionally, the circuit can be equipped with a reverse. This allows you to free the device from stones.
If you familiarize yourself with the assortment of manual trenchers, you can note for yourself that models that allow you to change the teeth of the chain are on sale. Manufacturers also offer models that are complemented by different chains. Depending on the specifics of a particular model, it can be equipped with:
- stroke reducer;
- hydraulic drive systems;
- cutting organs;
- mounted plows;
- mounted cable layers;
- dozer blade;
- special screws.
The latter are necessary for discarding the soil. There are also such equipment options that are complemented by other devices. The cutting unit can move due to the engine, whose power starts from 9 and ends with 15 liters. from. The operator will be able to easily control the device using levers, knobs and pedals.
The drive has a robust construction; it does not require particularly complicated maintenance. Many models do not require vertical shafts, belts and flywheels, which is ensured by the equipment of the devices with hydraulic pumps. Trenchers have a well-thought-out design, due to this, the operator has the opportunity to reduce the time for maintenance and repair.
Main advantages
A trencher, as mentioned above, is used to construct trenches. Subsequently, they are used to fill the foundation for future construction projects. However, trenches may be needed for laying gas and water pipes, as well as for other construction tasks.
Due to its compact size, such construction equipment is a convenient solution for forming depressions in hard-to-reach places. It is possible to work with the help of these units in any conditions, while trenches are obtained with smooth edges, and you can go deep by a minimum of 20 cm. The maximum value in this case is 1 m.
The manual trencher has the advantage of high productivity, which is especially true when compared with shovel operation. Dug ditches can be used for irrigation and drainage systems, the organization of automated irrigation in areas of impressive area.
Such machines are used to dismantle asphalt during construction and repair work. The technique is useful in landscaping around facilities whose construction has been completed. If you need to quickly lay a curb stone, then you can’t do without this device either.
Cons of trenchers
Trenchers have many advantages, but consumers note their disadvantages. Among the others and the first, high cost should be highlighted. It sometimes affects the fact that the buyer can not afford such a narrow-profile technique, because you have to use it infrequently. Another disadvantage is the expensive rental of equipment. In addition, you can use it only with certain skills. But if you nevertheless purchased such equipment, you may encounter the problem of its storage, because for this you will need to allocate a separate place.
However, a trencher in a private household can be useful only once or twice when you will be building a house and outbuildings. Therefore, before purchasing such an aggregate, you need to think three times, because otherwise you can spend money on an unprofitable purchase.
Description of the TKMG-1200 brand trencher
This small-sized handheld trencher is a device that does not require registration with the State Technical Supervision Authority. In the manufacture of this model of equipment, foreign components are used, this should include the Japanese gasoline engine. The drive of the working body is hydraulic.
Among the main advantages of this model are the following:
- durability;
- operational reliability;
- stepless speed adjustment.
You can adjust the rotation of the cutting chain yourself. We cannot but mention that this equipment is characterized by higher power due to the hydraulic drive. The gas engine runs exclusively on the rotation of the hydraulic pump.
The manual trencher TKMG-1200 has an acceptable cost. It is often compared with analogues produced in England, USA and Germany. However, foreign analogues, although equipped with a hydraulic actuator, are much more expensive. The advantages of this installation is not only the cost, but also the availability of additional options in the form of the ability to install winter chains. They provide anti-slip performance. The installation can be supplemented with a trailer for transportation to the place of work.
Model Specifications
If you need to carry out cable laying, then you can choose the TKMG-1200 installation. Its overall dimensions are 2850x880x1150 mm. Transport speed reaches 4 km / h. Depending on the depth to which it is necessary to dig a trench, as well as what soil to work with, the digging speed may vary, but it reaches 1.5 m per minute.
Before purchasing the equipment described, it is imperative to inquire what the depth will ultimately be. The TKMG-1200 trencher digs soil for 1200 mm. The width of the trench is 90 mm. This applies to the case when the "Arctic" chain is used, while the soil must correspond to the 4th category. If the chain trencher uses a summer chain, and the soil corresponds to the 1st or 2nd category, then the width of the recess will be 150 mm. The rated power is 16.4 kW or 22 liters. from. The fuel tank holds 20 liters.
More about model assignment
The above trencher is used to develop trenches in frozen and thawed soils of the 3rd category. The shape of the recess will ultimately be rectangular. In the soil, there can be inclusions of crushed stone, the diameter of the elements of which reaches 50 mm. As an exception, waterlogged or loose soils are where it is quite difficult to get a decorated trench.
This mini trencher is designed for use in temperate areas. You can work at any time of the year, while the temperature of the external environment should be a limit of -10 to +30 ° C. The relative humidity should not exceed 80%. It is important to pay attention also to the dustiness of the air - it should be less than 0.1 m 3 .
Additional device information
The structure of the trencher includes:
- housing;
- mounting plate;
- folding plow;
- bar chain;
- tension mechanism.
The case has a guide beam as part of it - a bar chain slides along it. The drive sprocket shaft and bearing are mounted in the drive bracket. The mounting plate consists of horizontal beams and brackets that correspond to the hitch. A mounting plate with six bolts is fixed to the housing.
Soil is removed from the edge of the trench with an asterisk and auger, which are mounted on the drive shaft. This design eliminates soil shedding back into the trench. If you have to work near fences or walls, then the auger must be removed. To do this, the screw for fastening the screw is loosened.
Cable digging trencher
Cable laying can be carried out using a trencher in the form of a cutter. It is designed to dig a deep and narrow trench. Such work can be carried out even in difficult rocky soil. Such equipment has high performance, and some models are even equipped with the ability to automatically feed the pipe. This allows you to further lay the electric cable and communication cables.
The cost of spare parts for equipment
The described technique is quite expensive, as are some parts for a trencher. For example, chains can be purchased on average for 45,000 rubles. But the driven asterisk costs 100 rubles.
Buy or rent
If you are associated with activities that require the regular use of the described units of special equipment, then it would be more advisable to purchase it than to lease it. However, it should be borne in mind that a manual small-sized trencher can cost you 150,000 rubles. minimum. The maximum cost reaches 500,000 rubles.
If you purchase a trencher to solve a specific problem, then it is better to rent it. The machine is selected individually, and the cost of leasing usually involves the remuneration of the operator, as well as the cost of additional materials.
Conclusion
