What is a Construction Power Trowel (Helicopter Concrete Machine)?
A Construction Power Trowel (commonly called a Helicopter Machine due to its rotating steel blades) is essential concrete finishing equipment used immediately after pouring and laser-screeding industrial concrete slabs. As the concrete begins to set, walk-behind or ride-on power trowels compact the surface, close capillary air voids, and work quartz/corundum surface hardeners into the slab to create a dense, level sub-base ready for epoxy coating or heavy traffic.
