Two Types Of Hydraulic Impact Pile Hammers

Based on the structure and working principle of the hydraulic impact hammer hammer, it can be divided into single-acting and double-acting types. The single-acting type refers to the hydraulic impact hammer pile driver hammer core being rapidly released to a predetermined height via a hydraulic device, allowing for free-fall pile driving. The double-acting type refers to the hammer core being raised to a predetermined height via a hydraulic device, then accelerated through the hydraulic system to increase the impact speed and drive the pile. This corresponds to two different pile driving theories.

The single-acting excavator impact hammer hammer corresponds to the heavy hammer, light-impact theory, characterized by a large hammer core weight, low impact speed, and long hammering time. Each impact of the single-acting hydraulic hammer pile driver hammer should have high penetration, making it suitable for pile types of various shapes and materials, with low damage rate and special settling rates.
