How to choose hydraulic hammers?

The working principle is similar to that of the electro-hydraulic hammer. After the improvement, the striking frequency can be increased, the oil temperature can be reduced, the service life can be prolonged, the quality of the forgings can be improved, and a lot of energy can be saved. Hydraulic hammer belongs to impact pile hammer, which can be divided into single-acting type and double-acting type according to its structure and working principle. The so-called single-acting type means that the impact hammer core is quickly released to a predetermined height by a hydraulic device, and the impact hammer core falls freely.

Double-acting type means that the impact hammer core is lifted to a predetermined height by a hydraulic device, and the acceleration energy is obtained from the hydraulic system to increase the impact speed. This also corresponds to the two piling theories. The single-acting Hydraulic Pile Hammer corresponds to the light hammer theory. It has the characteristics of large hammer core weight, low impact speed and long hammering time.
The pile hammer has a large penetration per strike, is suitable for pile types of various shapes and materials, and has a low damage rate, especially for concrete pipe piles. The double-acting hydraulic pile hammer corresponds to the light hammer and heavy hammer theory. It has the characteristics of low weight of hammer core, high impact speed and short action time of hammer pile. The impact energy is large, which is more suitable for steel piles.
