Electric vibratory hammer is used very commonly in piling foundation, especially in Southeast Asian countries. It’s designed as per resonance theory. When the pile forcing vibratory frequency is consistent with the soil vibratory frequency, the soil will occur resonance phenomenon. Meanwhile, the largest amplitude, sufficient vibratory frequency and acceleration will break the cohesion between the soil and pile. In that case the pile will disintegrate from the soil in a short time. Pile-sinking resistance especially side resistance will be reduced very quickly. Then the pile sinks under the gravity. As the sinking is depended on reducing the friction between the pile and the soil, it’s effective to extract the pile only using a little more force than the pile weight. As a result, the vibratory hammer develops rapidly and broadly used in pile driving and extracting construction.
Yongan machinery is one of the most professional vibratory hammer manufacturers in China with more than 30 years’ experience. The company has always devoted to the technological innovation and development of new products including DZ and DZJ series vibratory hammers. The product were applied in more than 300 large bridges such as Hangzhou Bay Bridge, Jintang Cross-sea Bridge in Ningbo City, and so on.), and won prizes and praises for the good quality and excellent performance.
Yongan electric vibratory hammer is suitable to drive and extract piles for different geological situation except the hard rock layer. For example, pre-made concrete pile, cast-in-place concrete pile, concrete expanded bore pile, lime pile, stone column. Besides, it’s widely used in cofferdam, trestle work, offshore working platform, and also wind mill single pile or group pile. It’s well equipped with good quality of spare parts of well-known brands, such as FAG bearing, Rexroth pump, shock-proof motor, and so on. The hammer includes low frequency and high frequency series. Low frequency hammer is best choice to drive piles in a stable and efficient path. High frequency can accelerate liquefy soil, reduce soil resistance, high efficiency and noise reduction. This series can adjust eccentric moment, which is good for the sticky clay and soil condition.
