Modern construction is no longer complete without earthmoving machines. One of them is a manual trencher. In a short time, it can be used to 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 range of similar products and understand that even the minimum cost for many may be unbearable. Therefore, before making a purchase, it is necessary to evaluate how often you will use the device, as well as what tasks you plan to set for them.
If the equipment will be used once during the construction of a country house and the construction of a bathhouse, then it is more expedient to consider the possibility of renting. This approach is also good because you will pay not only the cost of renting equipment, but also the services of a professional who will dig a trench according to your size in a short time.
Description
Manual trencher is a design ontracked or wheeled chassis. This guarantees excellent traction and stability, which is true even on uneven surfaces. The cutting unit is one of the important components. It has the appearance of a strong frame and a cutting chain with a tension sprocket. Additionally, the chain can be equipped with a reverse. This allows you to free the device from stones.
If you look at the range of manual trenchers, you will be able to note for yourself that models are on sale that allow you to change the chain teeth. Manufacturers also offer models that are complemented by different chains. Depending on the specifics of a particular model, it can be equipped with:
- speed reducer;
- hydraulic drive systems;
- cutting bodies;
- mounted plows;
- mounted cable layers;
- dozer blade;
- special screws.
The latter are needed to discard the soil. There are also such equipment options that are complemented by other devices. The cutting unit can move due to the engine, the power of which starts from 9 and ends with 15 hp. with. The operator will be able to easily control the device using levers, handles and a pedal.
The drive has a robust design, it does not require particularly complex 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 opportunityreduce maintenance and repair time.
Key Benefits
The trencher, as mentioned above, is used for trenching. 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, this construction equipment is a convenient solution for forming recesses in hard-to-reach places. You can work with the help of these units in any conditions, while the trenches are obtained with smooth edges, and you can go deep by at least 20 cm. The maximum value in this case is 1 m.
The hand trencher has the advantage of high productivity, which is especially true when compared with shoveling. Excavated ditches can be used for irrigation and drainage systems, organizing automated irrigation in areas of impressive area.
Such machines are used to dismantle asph alt pavement during construction and repair work. The technique is useful in landscaping areas around objects whose construction has been completed. If you need to quickly lay a curbstone, then you can’t do without this device either.
Cons of trenchers
Trenchers have many advantages, but consumers also note their disadvantages. Among others and the first should be highlighted the high cost. She issometimes it affects the fact that the buyer cannot afford such a narrow-profile technique, because it has to be used infrequently. Another disadvantage is the expensive equipment rental. In addition, you can use it only with certain skills. But if you still purchased such equipment, you may encounter the problem of storing it, because for this you will need to allocate a separate place.
However, a trencher in a private household may come in handy only once or twice when you are building a house and outbuildings. Therefore, before purchasing such a unit, you need to think three times, because otherwise you can spend money on an unprofitable purchase.
Description of the TKMG-1200 trencher
This manual small-sized trencher is a device that does not require registration with the Gostekhnadzor. In the manufacture of this model of equipment, foreign components are used, this should include a Japanese gasoline engine. The drive of the working body is hydraulic.
Among the main advantages of this model should be highlighted:
- durability;
- operational reliability;
- stepless speed control.
You can adjust the rotation of the cutting chain yourself. It should also be mentioned that this equipment has a higher power due to the hydraulic drive. Gasoline engine runs exclusively on rotationhydraulic pump.
The manual trencher TKMG-1200 has an acceptable cost. It is quite often compared with analogues produced in England, the USA and Germany. However, foreign analogues, although equipped with a hydraulic drive, are much more expensive. The advantages of this installation are not only the cost, but also the availability of additional options in the form of the possibility of installing winter chains. They allow you to provide anti-slip characteristics. The unit can be supplemented with a trailer for transportation to the job site.
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 the trench needs to be dug, as well as the soil to be worked with, the digging speed may vary, but it reaches 1.5 m per minute.
Before purchasing the described equipment, it is imperative to ask what the depth will be in the end. Trencher TKMG-1200 digs up soil by 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 hp. with. The fuel tank holds 20 liters.
Additional information about the purpose of the model
The trencher described above is used to develop trenches in frozen and thawed soils of the 3rd category. The shape of the recess will eventually turn out to be rectangular. In the soil there may be inclusions of crushed stone, the diameter of the elements of which reaches 50 mm. The exceptions are waterlogged or loose soils, where it is rather difficult to get a formalized trench.
This mini trencher is designed for use in temperate climates. You can work at any time of the year, while the ambient temperature should be between -10 and +30 °C. The relative humidity of the air should not be higher than 80%. It is also important to pay attention to the dust content of the air - it should be less than 0.1 m3.
Additional device information
The trencher includes:
- case;
- mounting panel;
- reclining plow;
- bar chain;
- tension mechanism.
The body has a guide beam - a bar chain slides along it. The drive sprocket shaft and bearing are installed in the drive bracket. The mounting plate consists of horizontal beams and brackets that fit the hitch. A mounting plate with six bolts is fixed to the body.
The soil is removed from the edge of the trench with the help of an asterisk and an auger, which are mounted on the drive shaft. This design eliminates the shedding of soil back into the trench. If you have to work near fences orwalls, the auger must be removed. To do this, the screw securing the auger is unscrewed.
Cable Ground Trencher
Cable laying can be carried out using a trencher in the form of a cutter. It is designed for digging deep and narrow trenches. Such work can be carried out even in difficult rocky soil. Such equipment has high productivity, and some models are even equipped with the ability to automatically feed the pipe. This allows further electrical and communication cables to be laid.
Cost of spare parts for machinery
