Power trowel is used in huge surfaces that need troweling the surface. Motor trowels are used to increase speed and efficiency, and in places where hand-held tools such as manual and telescopic screed are difficult and time-consuming.
Compared to manual tools, these power trowels increase efficiency by up to several times and reduce costs in the long run, as compared to manual tools.
Power trowel also improves the quality of the concrete surface and helps smooth and soften the concrete surface.
Most selling of power trowel:
Power trowels are sold in a variety of sizes, ranging from power trowel size 60 to power trowel size 120, which is the main criterion for selecting the project size to be performed.
Also note that the best-selling power trowel is among the 90cm models available.
The most important tips for buying power trowel:
Generally, the basis for selecting a power trowel is the size and dimensions of the project. Normal motor trowels are the best choice for small and medium-sized projects such as construction projects, flooring and areas where space is not possible to operate a manually operated propeller trowel because of space constraints.
Power manned trowels are most suitable for commercial and industrial projects of a very large extent, and the purchase of manned power trowels for large-scale projects is reasonable and economical.
Project dimensions, environmental conditions and if the project site has obstacles or non-obstacles must be taken into account when purchasing a regular power trowel.
For example, if the environment is warm, dry and stormy, it is advisable to use a propeller trowel with a more powerful motor that provides more torque at a lower speed and a greater weight to the concrete during operation.
For cooler climates and humid conditions, a small lightweight power trowel is the best choice. Note that the poured concrete saves more than three percent of the air inside the surface, which must be removed by hand tools such as vibrator hoses to create a suitable surface that is suitable for trowel operations. Note that the concrete surface troweling should not be initiated before leaving this air.
If there is more than 3% of air inside the poured concrete, this will cause serious problems in the final passes and when the concrete surface is polished by a motor trowel.
The most important factors that have a direct impact on the final surface of the concrete include choosing the right time to start the troweling and the location from which to start the concrete surface finishing operation.
One of the important things to pay attention to is the timing of the concrete surface, which is one of the best way to detect this is using the rule of footstep.
That way, when you step on the concrete surface, only 3 mm of your foot rest on the concrete surface.
There are, of course, other issues, such as project size, machine weight, operator speed during operation, and concrete surface characteristics.
Paying attention to the power trowel blade:
Another important thing is the power trowel blade that must be smooth and have a slight curvature in the corners to work perfectly. Fortunately, today the production of power trowel blades is booming in the country and these blades are manufactured in Iran with high quality, high performance and reasonable price.
Specifications and features to look for when selecting a power trowel:
Reliability, ergonomics of the machine (coordination of selected power trowel with human organs), equilibrium weight of the machine, good speed, high efficiency, equilibrium, low operator fatigue at work, cost savings, high safety are among important things to keep in mind when buying and choosing a regular or manned power trowel.
