The Hydraulic Pile Hammer is mainly installed and used on excavators, including land based excavators and amphibious excavators. Excavator pile drivers are mainly used for driving piles, including pipe piles, steel sheet piles, steel pipe piles, precast concrete piles, wooden piles, and photovoltaic piles driven on water.

The hydraulic pile hammer utilizes its high-frequency vibration to vibrate the pile body with high acceleration, transmitting the vertical vibration generated by the machinery to the pile body, causing changes in the soil structure around the pile and a decrease in strength due to vibration. The soil around the pile body liquefies, reducing the frictional resistance between the pile side and the soil. Then, the pile is sunk into the soil using the downward pressure of the excavator, the vibration sinker, and the self weight of the pile body. When pulling out the pile, use the lifting force of the excavator to lift the pile while vibrating on one side. The excitation force required for pile driving machinery should be comprehensive based on the soil layer, soil quality, water content, and the type and structure of the pile on the site
Operating principle:
1. The hydraulic pile hammer is equipped with two eccentric shafts, which are driven by hydraulic motors to generate high-speed rotation and vertical excitation force. After passing through the damping rubber block, it maintains a certain amplitude and can meet various types of soil and pile driving requirements.
2. The excitation force is proportional to the size of the eccentric shaft and the square of the number of vibrations. The eccentric shaft has undergone detailed calculation and testing, which can balance the strong excitation force and material characteristics, not only meeting work needs, but also ensuring mechanical reliability.
Matters Needing Attention:
1. The operator of the hydraulic pile hammer must be familiar with the equipment's structure, performance, and operating essentials.
2. Strictly follow the instructions for proper maintenance.
3. When the hydraulic pile hammer is working, all personnel should check the operation signals with each other in advance.
4. Before working on the hydraulic pile hammer, other unrelated personnel must stay away from the site
