A vibratory hammer is a construction tool used to drive piles into the ground. It works by generating high-frequency vibrations that reduce soil resistance, allowing the pile to penetrate more easily. This method is often used in foundation work for buildings and bridges. These hammers can be powered by hydraulic or electric systems and are typically mounted on excavators or cranes. The use of vibratory hammers is efficient and minimizes noise and vibration compared to traditional impact hammers, making them suitable for urban construction sites where noise regulations are strict.
