Advantages and Applications of EP Series Resonance Free Variable Frequency Variable Torque Vibration Pile Hammer

The vibrating pile hammer is one of the important equipment in pile foundation construction. It generates vibration through the rotation of an eccentric body, which can "liquefy" the soil around the pile, reduce the resistance between the pile and soil, and quickly achieve the purpose of sinking and pulling out the pile. Compared with other pile driving machinery, the vibrating pile hammer has both the functions of sinking and pulling piles, and can be used to produce prefabricated piles and cast-in-place piles.

Pile sinking and pile pulling functions

The vibrating pile hammer, with its high-frequency and low amplitude vibration characteristics, can control the lateral displacement of the pile body within 3mm during the pile sinking process, effectively avoiding damage to the pile head, especially suitable for soft soil foundation and dense pile group construction. Its non impact load operation method ensures the integrity of the concrete structure of the pile body, and reduces the comprehensive construction cost by 25% -30% compared to the hammering method. With the continuous expansion of China's infrastructure scale, the iteration speed of vibration pile hammer technology has accelerated, and it has become an indispensable equipment for modern pile foundation construction.

High efficiency, good results, and more economical

As the world's largest market for the production and application of electric vibration pile hammers, China's related technology has reached the international leading level.

The EP series resonance free variable frequency torque electric drive vibration pile hammer, one of the main products of Shanghai Zhenzhong with complete intellectual property rights, uses a hydraulic control eccentric torque conversion device to continuously adjust the eccentric torque of the vibration pile hammer from zero to the maximum value during start-up, shutdown, and operation. Due to starting and stopping under zero eccentric torque, the occurrence of "resonance" is avoided, and the amplitude can be adjusted to adapt to changes in soil conditions, making it highly adaptable and widely applicable. At present, this series of products is one of the advanced products in vibration pile hammers, and the products have been exported to developed countries such as Japan.

Export to various countries

The Shanghai Zhenzhong EP series resonance free variable frequency torque electric drive vibration pile hammer has the characteristics of compact structure, convenient use, and high efficiency. It can smoothly and freely adjust the eccentric torque from "0-maximum" or "max-0" during the starting, stopping, and running processes, realizing the machine's ability to adjust the eccentric torque freely for different working conditions, soil types, etc.

The advantages of Shanghai Zhenzhong EP series resonance free variable frequency torque electric drive vibration pile hammer compared with traditional ordinary electric vibration pile hammer are as follows:

This machine can be started under non eccentric torque conditions with a small starting load. Solved the problem of requiring a large capacity power supply for starting ordinary electric vibration pile hammers with eccentric torque, which was previously widely used.

02 overcomes the "resonance" caused by starting and stopping with eccentric torque, enabling the machine to start and stop smoothly and freely. Preventing the occurrence of severe vibration noise and damage to other components caused by resonance.

The 03 large vibration hammer adopts a variable frequency vibration resistant dual output shaft motor, and the drive belts are symmetrically installed on the front and rear pulleys of the exciter, which disperses and distributes the force on the shaft evenly, reduces the pressure on the bearing, and lowers the temperature rise of the bearing without being easily damaged.

No resonance, environmentally friendly

In recent years, Shanghai Zhenzhong has re created the EP series resonance free variable frequency torque electric drive vibration pile hammer and successively developed EP120KS、EP160、EP160KS、EP200、EP240、EP240KS、EP320、EP320KS、EP400、EP550、EP650、EP800、EP1100、EP1600 The mechanical structure of electric vibration pile hammers of the same model, especially for large electric vibration pile hammers, has been deeply optimized, further expanding the applicability of the equipment and improving product quality.

In terms of structural design, the large vibrating hammer has been changed from a traditional vertical structure to a horizontal structure, which reduces the center of gravity of the equipment, improves operational stability and safety, and reduces working noise. The new beam type independent vibration reduction device is directly connected to the exciter, simplifying the installation and disassembly process, reducing the overall height of the machine, and avoiding the risk of collision between traditional suspension type vibration reduction structures and motors. This design not only enhances the vibration reduction effect, but also facilitates equipment transportation and maintenance.
