Power trowels are used to perform work on finishing freshly poured concrete horizontal surfaces on objects of any complexity and are designed to smooth the concrete surface at the device on concrete floors. Are driven by a gasoline engine or electric motor. The device allows the housing to monitor the area of ​​grouting. You can control the angle of the blades.

trowel is used most often when laying screeds for concrete surface grinding. Smoothing the concrete surface with helicopter building takes place in two stages. The first phase (coarse smoothing) – involves the use of scratch disk, which is mounted on the blade. The second stage (final smoothing) – smoothing machine made ​​blades without the use of disks.
