Product Description
Introduction

The FV-700 is a heavy‑duty Four eccentric mechanism system pile driver engineered for 65–75 ton excavators, designed to drive and extract large steel sheet piles, steel casings, and PC hybrid piles up to 24 meters in length. This machine leverages a dual pump flow merging system that increases hydraulic flow from 380 L/min to 700 L/min (with 1.5 inch piping) on demand, delivering exceptional excitation force (915 kN) to overcome dense boulder clay, weathered rock, and deep permafrost. The low maintenance cost design – featuring an integrated bearing self‑lubrication system inside the gearbox – eliminates daily greasing, dramatically extends bearing life, and reduces total ownership cost. With low noise eco friendly operation (hydraulic drive vs. diesel hammers), the FV-700 meets strict urban and environmental noise regulations. Despite its massive power, the compact structure confined spaces design keeps overall dimensions minimal, allowing it to work in congested port yards, bridge abutments, and industrial sites where traditional large pile drivers cannot fit. Equipped with German FAG bearings, original Parker motors, a super‑strong cast steel clamp (650 kN clamping force), and an electronic control system, the FV-700 is the ultimate solution for mega‑infrastructure projects across Southeast Asia, India, and Russia.

Key Features & Advantages (Integrating the 5 Keywords)
Feature Benefit for Large-Scale Piling Projects
Four eccentric mechanism system Four eccentric weights rotate in opposite pairs. Horizontal forces cancel completely, minimizing lateral vibration and protecting the excavator. Vertical forces sum to produce 915 kN of pure impact. Drives 24 m piles straighter, faster, and with less operator fatigue than two‑eccentric designs.
Dual pump flow merging system Standard flow of 380 L/min handles normal soils. When ground gets tough (gravel lenses, weathered rock, permafrost), activate the merging valve to combine dual pump flow – boosting flow to 700 L/min and increasing excitation force by ~40%. No need for a larger carrier.
Low maintenance cost design The gearbox houses a continuous oil circulation system that bathes all bearings. No daily greasing of hard‑to‑reach points. Oil change intervals are 1000 hours. Compared to conventional greased bearings, maintenance labour is reduced by 80% and bearing life is extended by 3x – drastically lowering total cost of ownership.
Low noise eco friendly operation Hydraulic drive eliminates the deafening impact noise of diesel hammers. Typical sound level at operator position is under 85 dB – low enough for night work in residential zones, near hospitals, or in ecologically sensitive areas. Meets IFC environmental standards for construction noise.
Compact structure confined spaces Despite 915 kN of force, the FV-700 maintains a slim profile (arm weight only 1000 kg, hammer weight 3850 kg). The short overall length allows operation inside sheet pile cofferdams, under bridge decks, or between closely spaced piles. No need for oversized swing radius.

Why FV-700 for Southeast Asia, India & Russia

Southeast Asia (mega port terminals, deep foundations, mixed soils)

India (large bridge piers, heavy metro viaducts, variable geology)

  • Four eccentric mechanism system with 915 kN impact handles the mixed ground of the Deccan Plateau – from basalt to alluvium.

  • Dual pump flow merging system overcomes weathered rock and gravel layers common in Western Ghats and central India.

  • Compact structure confined spaces fits inside cofferdams for bridge pier construction, eliminating the need for crane‑mounted hammers.

  • Low maintenance cost design keeps machines running reliably across remote bridge sites with limited maintenance access.

Russia (permafrost, deep industrial piles, Arctic conditions)

  • Low maintenance cost design eliminates cold‑weather greasing – the continuous oil bath uses low‑temperature hydraulic fluid, preventing bearing starvation at -30°C.

  • Dual pump flow merging system delivers the extra punch needed to break through frozen active layers and ice‑rich permafrost.

  • Four eccentric mechanism system with German FAG bearings and low‑temperature seals operates reliably in Arctic conditions.

  • Low noise eco friendly operation allows piling near residential areas in cities like Norilsk or Yakutsk without disturbing communities.

FAQ (Frequently Asked Questions)
Q1: How does the four eccentric mechanism system improve pile straightness?
A: In a Four eccentric mechanism system, two pairs of eccentric weights rotate in opposite directions. The horizontal components cancel each other, producing virtually no lateral vibration. The vertical components add up, delivering pure vertical impact. This prevents the pile from wobbling or bending, which is critical for driving 24 m long piles straight into the ground – reducing rejection rates by over 30% compared to two‑eccentric hammers.
Q2: When should I activate the dual pump flow merging system?
A: Use the dual pump flow merging system when the standard 380 L/min flow cannot maintain a penetration rate of at least 5 m/min. Typical scenarios: entering a dense gravel lens, weathered rock layer, or permafrost. The merging valve boosts flow to 700 L/min, increasing excitation force from ~650 kN to 915 kN. Once the hard layer is passed, switch back to standard flow to save fuel.
Q3: What makes the low maintenance cost design so effective?
A: Conventional pile drivers require daily greasing of 6–10 bearing points, often in hard‑to‑reach locations. The FV-700’s low maintenance cost design uses a closed‑loop oil circulation system inside the gearbox. Bearings are continuously oil‑bathed, never need manual greasing, and last up to three times longer. This reduces maintenance labour by 80%, eliminates grease disposal costs, and prevents bearing failures caused by missed greasing.
Q4: Is low noise eco friendly operation really possible at 915 kN?
A: Yes. The FV-700 is hydraulically driven, not impact‑based. The sound is a smooth hydraulic hum combined with the soil liquefaction noise – typically 80–85 dB at 7 meters. Diesel hammers of equivalent power (e.g., 10‑ton drop hammers) exceed 110 dB. The low noise eco friendly operation allows you to work in noise‑sensitive areas without expensive acoustic barriers, and often permits night shifts under local noise ordinances.
Q5: How compact is the compact structure confined spaces design?
A: The FV-700’s overall height (including clamp) is approximately 2.5 m, and the width (excluding the pile) is under 1.5 m. This compact structure confined spaces design allows it to operate inside sheet pile cofferdams as narrow as 2.5 m, under bridge decks with 3 m clearance, or between existing pile rows spaced 2 m apart. A traditional crane‑suspended vibratory hammer would need much more room.
Q6: What excavator size is required for the FV-700?
A: The FV-700 fits 65–75 ton excavators. It requires a hydraulic flow of 380 L/min at 32 MPa (with merging capacity up to 700 L/min). Compatible models include Komatsu PC650‑PC700, Hitachi ZX650‑ZX750, Liebherr R960‑R980, Sany SY650‑SY750, and similar class carriers.
Q7: Can the FV-700 drive piles longer than 24 meters?
A: While the FV-700 is rated for 24 m max pile length, the four eccentric series includes larger models (FV-800 and FV-900) capable of driving piles up to 32 m. Contact us for specific recommendations based on your pile type and ground conditions.
Q8: How does low maintenance cost design benefit remote jobs in Siberia?
A: In remote Siberian locations, sending a maintenance technician every week to grease bearings is logistically difficult and expensive. The low maintenance cost design requires only a bi‑annual oil change. The sealed system also prevents contamination from dust and snow, ensuring reliable operation even when temperatures drop to -40°C (with appropriate hydraulic oil).
Q9: Can the dual pump flow merging system be retrofitted to older machines?
A: The system is integrated into the FV-700’s electronic control and hydraulic manifold. It is not a standalone add‑on. However, older FV series machines can be upgraded to this specification at our factory. Please contact our service department for retrofit feasibility.
