High-frequency vibration reduces resistance for smooth penetration — as a mainstream excavator piling attachment, the excavator mounted vibratory hammer has become an efficient “tool” for infrastructure projects, thanks to its scientific structural design and strong adaptability.【WhatsApp/WeChat/Phone】+86 13837122632
How Does the Excavator Mounted Vibratory Hammer Penetrate Soil Efficiently?
- Power generation: Two built-in eccentric shafts rotate at high speed in opposite directions driven by a hydraulic motor, generating strong centrifugal force.
- Excitation force synthesis: These centrifugal forces superimpose vertically to form periodic excitation force (or vibration force) of up to tens of tons.
- Energy transmission: The excitation force is transmitted to the pile through special shock-absorbing rubber blocks. While buffering harmful vibrations and protecting the excavator structure, the shock-absorbing rubber blocks maintain an ideal operating amplitude of 3-8mm.
- Soil liquefaction: High-frequency vibration temporarily disrupts the structure of soil particles around the pile tip, sharply reducing frictional resistance. The pile penetrates smoothly under its own weight and the downward pressure of the equipment, enabling fast, low-noise piling and pile extraction operations.
What is an Excavator Mounted Vibratory Hammer?
Excitation force, measured in tons (t), is the core parameter determining the working capacity of an Excavator Vibratory Hammer. It directly dictates the soil resistance the equipment can overcome. Improper selection will lead to low efficiency or equipment damage.
- Matching excavator tonnage is a prerequisite: Excitation force must match the excavator’s weight and hydraulic power. Small excavators cannot safely carry or drive hammers with excessive excitation force.
- Determine specifications based on geology and pile type: On the premise of matching the excavator, choose excitation force “higher rather than lower”. Moderate models are suitable for loose sand and clay; for compact sand, gravel, or construction of long piles and large-diameter piles, select equipment with higher excitation force to ensure construction efficiency.
Hydraulic Pile Driver vs. Excavator Mounted Vibratory Hammer
Hydraulic pile driver: “Drills” into the soil through bit rotation, mainly used for pilot drilling of cast-in-place piles, micro-pile installation, or in conditions requiring soil extraction and replacement. It causes little soil disturbance, but the bearing capacity of the pile depends on subsequent pouring processes.
Excavator Mounted Vibratory Hammer: Excels in extremely fast construction speed, especially suitable for driving precast piles (such as steel sheet piles, steel pipe piles, H-beam piles) and efficiently completing pile extraction. It drives the pile into the soil through vibration, providing good lateral frictional resistance. For projects with tight schedules and mainly driven piles, it is usually a more economical and efficient choice.
Advantages of YG Vibratory Pile Driver for Excavator
- More stable transmission system: Adopts a self-lubricating and cooling gearbox with excellent ventilation and heat dissipation. The innovative box structure ensures concentricity, extending gear service life by 50% and guaranteeing construction progress.
- More durable structural design: Reinforced detachable boom and rotating shaft with additional oil passages not only have a longer service life but also facilitate daily maintenance and component replacement.
- Safer and more reliable operation: Built-in gear design prevents contamination and accidental collisions. Cast steel fixtures paired with cylinder pressure-retaining locks firmly secure the pile, eliminating the risk of slipping during piling.
- More flexible adaptability: The full range of models covers 8-55t excavators. The hydraulic system is highly compatible with mainstream excavator brands, requiring no complex modifications for attachment retrofitting.

Maintenance Tips for the Excavator Pile Driver
- Daily inspection: Before and after operation, check for hydraulic oil leaks in hoses, ensure all connecting bolts (especially those connecting to the excavator and fixture) are tight, and inspect shock-absorbing rubber blocks for cracks or excessive wear.
- Regular lubrication: Strictly follow the maintenance manual to regularly inject specified grease into the oil passages of the boom, rotating shaft and other parts through oil nozzles — this is key to reducing wear and extending service life.
- Hydraulic system care: Ensure the cleanliness of the excavator’s hydraulic oil meets standards and monitor oil temperature. Good hydraulic oil condition is the foundation for protecting the equipment’s internal precision hydraulic motors and valve groups.
- Long-term storage: When the equipment is not in use, clean the surface, apply anti-rust grease to exposed metal parts, and store it in a dry place.
