Shanghai Zhenzhong's new product EP1300H submersible resonant free hydraulic vibration hammer with large eccentric torque unveiled at BMW exhibition

EP1300H submersible eccentric moment infinitely adjustable resonance free hydraulic vibration impact hammer is a high-end equipment specially designed for deep-sea underwater large-scale pile foundation construction, newly developed by Shanghai Zhenzhong Construction Machinery Technology Co., Ltd. This new product not only integrates Shanghai Zhenzhong's profound technical accumulation in the field of vibration hammers, but also comprehensively optimizes its structure and innovates its functions to address the unique challenges of deep-sea water pile construction. It aims to become the core key equipment for future deep-sea offshore wind power foundation construction, especially for deep-sea anchor pile construction of floating wind turbine platforms and deep-sea subsea pipeline wind power foundation construction.

Its main features include:

1. Eccentricity infinitely adjustable and zero eccentricity starting and stopping:

EP1300H adopts advanced hydraulic control eccentric transformation device, which realizes stepless adjustment of eccentric torque from zero to the design maximum value, allowing the amplitude to be smoothly adjusted from "0-maximum" or "max-0", perfectly adapting to the requirements of pile sinking and pulling in different soil types.

The zero eccentric torque start and stop function effectively avoids the resonance problem caused by traditional vibration hammers with eccentric torque start and stop, protecting the equipment from resonance damage and significantly reducing the impact of noise and vibration on the surrounding environment.

2. Extremely large eccentricity and strong vibration impact impulse:

The machine is designed with a large eccentric moment, coupled with a powerful hydraulic drive system, which can generate a huge vibration impact impulse, easily meeting the sinking needs of heavy piles and in dense and hard soil layers, improving construction efficiency and quality.

3. The overall structure of the vibration impact pile hammer adopts a horizontal structure:

The horizontal structure design ensures a low center of gravity and good stability of the entire machine, allowing it to maintain a stable operating state even in deep-sea environments.

At the same time, coupled with an efficient lubrication system and vibration reduction device, the reliability and durability of the pile hammer under long-term high-intensity operation are ensured.

4. Adopting pressure difference compensation technology to meet the construction requirements of large piles in ultra deep seawater:

EP1300H specifically adopts pressure differential compensation technology, which enables pile hammers to perform stable and efficient pile construction operations in ultra deep seawater (up to 120m), providing strong technical support for the construction of offshore wind power foundations in deep seas.

In addition, EP1300H inherits the consistent high quality and reliability of Shanghai Zhenzhong products, and its excellent performance and innovative design concept have won widespread attention and praise from the industry at the bauma CHINA 2024 exhibition in Shanghai. Shanghai Zhenzhong Construction Machinery Technology Co., Ltd. has always been committed to providing global customers with more efficient, environmentally friendly, and safe construction machinery solutions through technological innovation and product upgrades. EP1300H is an outstanding representative of this concept.
