A plate compactor is a construction tool used to compress soil, gravel, or asphalt. It features a heavy, flat plate that vibrates to increase the density of the material beneath it. This tool is essential for preparing surfaces for foundations, driveways, and walkways, ensuring stability and reducing the risk of settling. These machines come in various sizes, making them suitable for both small and large projects. Operators typically use gasoline or diesel engines to power the compactor. Safety features, such as handles and protective covers, help ensure safe operation while minimizing the risk of injury.
