Impact hammers are tools used to deliver a strong, sudden force to a surface or object. They are commonly employed in construction and engineering for tasks such as driving piles into the ground or breaking concrete. The design typically features a heavy weight that is dropped or swung to create a powerful impact. These hammers can be powered by various means, including manual operation, hydraulic systems, or pneumatic mechanisms. The effectiveness of an impact hammer depends on its weight, drop height, and the material being struck. They are essential in ensuring structural integrity in projects involving construction, geotechnical engineering, and demolition.
