Although a conventional piling rig with a free-hanging hammer can install maybe 20 pairs of sheets a day, the LRB 125—fitted with a high-frequency vibratory hammer with variable moment—achieves 75 pairs a day (equivalent to 300 ft.). The machine’s hammer generates a downforce equivalent of 33,700 lbs. Liebherr Nenzing Crane Co. 866-879-6312.
