What are Hydraulic Hammers?

Hydraulic hammers are impact type pile hammers, which can be divided into single-acting and double-acting according to their structure and working principle. The so-called single-acting type means that the impact hammer core is quickly released after being lifted to a predetermined height by a hydraulic device, and the impact hammer core hits the pile body in a free-fall manner; the double-acting type means that the impact hammer core is lifted to a predetermined height by the hydraulic device, The system obtains acceleration energy to increase the impact speed and strike the pile. This also corresponds to two pile driving theories. The single-acting hydraulic pile driving hammer corresponds to the heavy hammer light driving theory. It is characterized by a larger hammer core weight, lower impact speed, and longer hammer action time. Large penetration, suitable for piles of various shapes and materials, low damage rate, especially suitable for concrete pipe piles. The double-acting hydraulic pile driving hammer corresponds to the light hammer heavy driving theory. It is characterized by a smaller core weight, a higher impact speed, and a shorter hammer pile action time. It has a large impact energy and is most suitable for driving steel piles.
