Hydraulic hammers belong to impact foundation piling hammers. According to their structure and principle, hydraulic piling hammer manufacturers can be divided into single function and double function. To put it bluntly, the single-effect type means that the impact hammer core is quickly released after the hydraulic device is increased to a predetermined aspect ratio, and the impact hammer core severely hits the pile through free fall; the double-effect type means that the impact hammer core is raised to a predetermined height according to the hydraulic device After the aspect ratio, the instantaneous speed kinetic energy is obtained from the hydraulic transmission system to increase the impact rate and severely hit the pile.
This also matches the two foundation piling foundation theories. The single-effect hydraulic foundation piling hammer matches the heavy-hammer light-driving basic theory, which has the characteristics of the net weight of the hammer core, the low impact rate and the long impact time. The pile hammer has a large penetration per stroke and incorporates pile types of various appearances and materials, and the pile damage rate is low, especially for concrete pipe piles. The dual-effect hydraulic foundation piling hammer matches the basic theory of light hammer heavy piling. It has the characteristics of small hammer core weight, high impact rate, short hammer effect time, high impact performance, and more suitable for steel pile driving.
Hydraulic foundation piling hammers have completely replaced diesel foundation piling hammers and become the main force in the foundation piling sales market. With the development of social civilized behavior and economic development trend, it is imperative to replace diesel foundation piling hammer with hydraulic foundation piling hammer, which is a representative of the national industrial production level and civilized behavior level.
