Principle of operation with the
There are various types of floors: magnesian, polymeric, linoleum and so on. However, the basis for all of them is a concrete slab. Here it must be carefully leveled. For these purposes, a trowelling machine for concrete is used. With its help, the surface is monolithic, which increases the service life of floor coverings. At the same time, labor costs are minimal.
The surface with the machine is processed in two stages. The first thing to do is eliminate all the irregularities and swings that are inevitable in the concreting process. It is done by trowel disks. To eliminate the irregularities, you can start after the traces of walking are no longer on the concrete. Then the grouting starts with the trowel. This process makes the final leveling of the floor. Blades on the machine are placed at an angle of 10 degrees, and the speed of rotation is made maximum.
Tip! In order to maximize the quality of the work, the blades must be regularly changed.
Versions of the
unit The machine can have one or two engines. It works according to the following principle: the engine, which is firmly attached to the frame, rotates the blades or grinding discs, due to which the grouting of concrete occurs. The engines are gasoline or electric, in the manner of lawn mowers. Accordingly, fuel is gasoline or electricity. Machines with a gasoline engine have more power, but the electric motor allows you to work in enclosed spaces. In addition, electrical devices are much cheaper than gasoline "brothers".
There are several types of machines:
- Manual;
- Self-propelled;
- Standalone.
Manual single-rotor trowels are very manoeuvrable and easy to use. Without them, it is difficult to do work in limited spaces and corners. Due to their mobility, they are often used in the construction of multi-storey buildings. Self-propelled twin-engine vehicles are equipped with an operator's chair. They are used for work in large rooms. Also there are fully autonomous devices, but their price is very high, so they are rare.
Note! Despite the high cost of stand-alone devices, the costs for them are quickly justified.
Concrete trowelling machine: how to choose it?
Appropriate selection of the grinding machine is necessary very carefully. Choose them, focusing on the expected areas on which the concrete will be grouted. If you plan to use the device every day, it is recommended to give preference to more powerful units. It will cost an order of magnitude more expensive machines with lower power, but this will allow grouting every day and for a long time to operate the device.
Note! The grouting quality does not depend on the type of engine.
More powerful machines are vehicles with a gasoline engine. However, as mentioned above, they are not recommended for use in small areas and non-ventilated areas due to exhaust from the engine. However, without these machines can not do on construction sites, which are not supplied with electricity. Another advantage of the gasoline engine is that there is no wire that can interfere with the operation. In turn, the electric device is cheaper and mobile. So when choosing, one should be guided by specific working conditions.
