Overview

The excavator-mounted vibratory pile driver (also known as a vibro hammer) is a hydraulic vibratory hammer designed for installation on excavators. It is suitable for both land-based and amphibious excavators. The vibratory pile driver can be used for both pile driving and pile extraction, making it a versatile tool for foundation construction. It is capable of driving various types of piles, including sheet piles, H-piles, pipe piles, and photovoltaic piles.
This equipment is particularly suitable for municipal projects, bridges, cofferdams, and building foundations. With low noise and minimal vibration, it meets urban construction standards.

Working Principle

The hydraulic vibro hammer utilizes high-frequency vibration to generate a strong vertical force, transmitting the vibration to the pile. This process loosens and liquefies the surrounding soil, reducing the friction between the pile and the ground. With the excavator’s downward pressure and the pile’s self-weight, the pile is driven smoothly into the soil.
For pile extraction, the vibratory pile driver uses single-sided vibration while leveraging the excavator’s lifting force to remove the pile efficiently.

Advantages

• High Efficiency

The excavator vibratory pile driver operates at an average speed of 3 minutes per pile, with a maximum efficiency of up to 12 meters per minute (in non-silty soil). Compared to pneumatic hammers and diesel hammers, its efficiency improves by 40%-100%. This enables rapid completion of piling tasks, significantly shortening construction timelines. In large-scale construction projects, it ensures fast pile installation, allowing more time for subsequent operations.

• Wide Application Range

The vibro hammer can drive various types of piles and is equipped with interchangeable pile clamps designed for different pile structures.
BeiYi Machinery offers eight types of jaws to suit different working conditions.

• Energy-Saving & Environmentally Friendly

The excavator-mounted vibratory pile driver consumes less energy and generates lower noise levels, making it compliant with environmental regulations while reducing its impact on surrounding areas. This makes it highly favored in urban construction projects.

• Flexible & Adaptable

With excellent mobility and flexibility, the vibratory pile driver can operate in diverse site conditions, from narrow alleys to open construction sites. It can also adjust pile positions and angles according to project requirements, ensuring adaptability to different engineering needs.

Conclusion

The excavator-mounted vibratory pile driver (vibro hammer) is an efficient, versatile, and environmentally friendly piling solution. With its high speed, adaptability to various pile types, and reduced energy consumption, it is widely used in urban and infrastructure construction. Its ability to operate in different environments with minimal impact makes it a preferred choice for modern piling projects.
