What is the stroke on a pile hammer?

The stroke on a pile hammer refers to the distance that the hammer falls before striking the pile. This distance is crucial because it determines the energy imparted to the pile during driving, influencing the penetration and effectiveness of the pile installation. A longer stroke generally results in greater energy transfer, while a shorter stroke may be used for more controlled driving in sensitive environments. Proper stroke length is essential for achieving the desired performance and integrity of the pile foundation.
