Concrete trowelling machines, also known as concrete finishing machines or trowel machines, are specialized tools used for the processing of freshly poured concrete surfaces after their placement. These machines play a crucial role in the final finishing of concrete surfaces, ensuring uniformity, smoothness, and durability of the concrete. Here are some key features and applications of concrete trowelling machines:

1. Working Element: Concrete trowelling machines typically feature a rotating working element known as a trowel disc or trowel blade. This element is used to process the top layer of fresh concrete, giving it a smooth and even texture.

2. Adjustable Trowelling Depth: Many trowelling machines have mechanisms for adjusting the trowelling depth, allowing the user to control the amount of material removed from the concrete surface. This is important for achieving the desired finish.

3. Types of Trowel Discs: Depending on the required finish, trowelling machines can use various types of trowel discs, including smooth discs and textured discs for creating non-slip surfaces.

4. Electric or Gas-Powered: Trowelling machines can be electrically powered or run on gasoline, depending on the availability of a power source and specific task requirements.

Concrete trowelling machines are essential tools for achieving high-quality concrete surfaces, providing the necessary smoothness and texture. They enhance the aesthetics and functionality of concrete structures.
