Background

The hydraulic hammer belongs to an impact pile hammer and can be divided into a single-acting type and a double-acting type according to the structure and the working principle. The single-acting type means that the impact hammer core is lifted to a preset height through a hydraulic device and then is released quickly, and the impact hammer core strikes a pile body in a free-falling mode; the double-acting type means that after the impact hammer core is lifted to a preset height through a hydraulic device, acceleration energy is obtained from a hydraulic system to increase impact speed so as to strike a pile body. The single-action hydraulic pile hammer is corresponding to a heavy hammer light driving theory, is characterized by larger weight of the hammer core, lower impact speed and longer hammering action time, has large penetration per driving of the pile hammer, is suitable for pile types of various shapes and materials, has low pile damage rate and is particularly suitable for driving concrete pipe piles.
