Hammer efficiency refers to the ratio of kinetic energy of the hammer to the rated energy1. Energy efficiency is the efficiency of the hammer in terms of energy consumption and output2. A hammer may be more energy efficient than a diesel hammer2. Hammers driving a batter pile are driving at an angle, so they do not fall as far through the gravity field as those driving plumb piles, reducing their energy3.Learn more:✕This summary was generated using AI based on multiple online sources.
