[0002] Hydraulic impact hammer is an impact pile hammer, which can be divided into single-acting and double-acting types according to its structure and working principle. The so-called single-acting type means that the impact hammer core is lifted to a predetermined height by a hydraulic device and then quickly released, and the impact hammer core strikes the pile body in a free-falling manner; the double-acting type means that after the impact hammer core is lifted to a predetermined height by a hydraulic device, it obtains acceleration energy from the hydraulic system to increase the impact speed and strike the pile body.
