YEKUN Weiboro FV-600 high frequency vibration hammer | 920 kN high centrifugal force – ultra-class PV pile driver that crushes difficult geological conditions
At the top of the YEKUN Weiboro FV series is the FV-600, a high frequency vibratory hammer designed for 55-70 ton excavators. With a rated high centrifugal force of 920kN delivered at 2800rpm, this machine doesn't just drive piles - it overcomes challenging geological conditions that stop other hammers: massive boulder deposits, dense glacial till and layers of weathered limestone.
The FV-600 functions as a dedicated PV pile driver for gigawatt-scale solar farms, but its 21-meter maximum pile length and enormous clamping force make it equally capable of driving heavy sections of composite walls, large-scale steel tubular piles, and precast concrete piles for deep-sea bridge foundations.
Any pile within its reach is immersed or retrieved on command.
What provides such strength? The heart of the hammer is a forged eccentric shaft with a torque rating of 12.5 kgm, supported by German precision bearings with a double lip seal system that prevents the entry of contaminants even when plunged into dirty trenches. The service life of these bearings at full load is 3000 hours. The body is made from 12mm wear-resistant steel plate, robotically welded with full penetration at all stressed joints.
A compact and lightweight design may seem impossible for a hammer head weighing 4200kg (plus 950kg boom), but the FV-600 measures just 1650mm long, 850mm wide and 3100mm high. This footprint allows it to be transported on low-load trailers without special permits and to work inside sheet piles or between existing pile caps. The universal mounting system fits any excavator from 55 to 70 tons, including Caterpillar 349-374 models.
When the ground refuses to give way, the dual pump flow fusion system provides a decisive response. The activation of the second stage vibration combines two high-flow hydraulic circuits (total flow rate up to 500 l/min at 32 MPa), creating a sudden burst of excitation that breaks down cohesive soil structures and instantly liquefies dense sand layers. Operators report that the FV-600 turns what was previously a “drill first, plug later” procedure into a one-pass operation.
The valve block has a degree of protection IP67, completely sealed against dust and immersion in water. It separates clamping, lifting and vibration into independent colored circuits. A technician can replace a faulty solenoid cartridge in 20 minutes without special tools. As a pure piling solution for an excavator, the FV-600 receives all hydraulic power from the base carrier - no auxiliary motor, no umbilical hoses to a separate power unit, no additional fuel consumption.
The clamping force exceeds 1000 kN (calculated), with parallel jaws that are automatically centered according to pile thickness from 10 to 50 mm. Jaw tips are reinforced with tungsten carbide for long service life in abrasive soils.
For contractors who regularly face the most challenging geological conditions—think offshore wind foundations or high-rise basement excavation in rocky soil—the YEKUN Weiboro FV-600 High Frequency Vibratory Hammer is the ultimate PV piling hammer and deep foundation tool. It turns impossible ground into routine production.
