DZ150A Vibratory Hammer – 150 KW Motor + 12.5 Mm Amplitude – Ideal For Offshore Foundations And Cofferdams In Russia

The DZ150A Electric Vibratory Hammer is a heavy-duty piling solution from the DZ Series, designed for large-scale foundation projects that demand exceptional power and reliability. Suspended from crawler cranes with a minimum 80-ton capacity, this machine delivers outstanding performance for both pile driving and extraction in the most challenging soil conditions – from dense gravel to frozen permafrost.

The DZ150A handles an extremely wide range of pile types: steel sheet piles (for large retaining walls and cofferdams), heavy I-beams and H-sections, steel pipe piles (up to 2500 mm diameter), precast concrete piles (square or round, up to 2500 mm), and stone columns for deep ground improvement. Its dual clamp option (single/dual selectable) provides secure gripping for extra-large diameter piles – a critical advantage for offshore ports, bridge foundations, and high-rise building projects in Vietnam, India, and Russia.

• Eco-Friendly & Low-Noise Operation
  Despite its massive power, the DZ150A operates with significantly lower noise than diesel hammers. This is essential for projects near residential areas or environmentally sensitive zones, including night work permits in Ho Chi Minh City, Mumbai, and St. Petersburg.

• High-Grade Vibration-Resistant Motor
  A 150 kW leading domestic brand motor delivers stable, long-lasting performance under continuous high-intensity vibration. The motor is engineered to perform reliably in Russian sub-zero temperatures (down to -30°C with proper cold-weather grease) and the tropical humidity of Southeast Asia.

• Intelligent Wireless Remote Control
  The integrated distribution box features wireless remote control for safe one-person operation. The baked enamel finish provides superior rust resistance – critical for coastal and offshore projects in Vietnam and India (e.g., port terminals, seawalls, and oil rig foundations).

• Renowned Frequency Converter
  Simplifies troubleshooting and reduces downtime. Local technicians across India, Vietnam, and Russia can easily maintain the unit, lowering service costs and maximizing uptime.

• Single/Dual Clamp Type
  The DZ150A supports both single and dual clamp configurations. Use single clamp for standard sheet piles and H-beams; switch to dual clamp for large-diameter steel pipe piles (up to 2500 mm) or heavy concrete piles to ensure secure, even gripping.

• High Exciting Force (1387 kN)
  One of the highest in its class. This force easily penetrates dense sands, gravels, stiff clays, and even frozen ground – ideal for Russian permafrost and Indian laterite soils.

• Substantial Total Weight (14,500 kg)
  The heavy machine weight (14.5 tons) improves energy transfer to the pile, reducing vibration loss and increasing driving efficiency for extra-long piles.

The DZ150A is the optimal choice between the DZ135A (9.5 t) and DZ180A (14.5 t as well but higher power).

• Offshore and port foundations – Driving large-diameter steel pipe piles (up to 2500 mm) for jetties, quay walls, and oil terminals in Vladivostok, Chennai, or Ho Chi Minh City.

• Bridge cofferdams – Installing steel sheet piles for deep-water bridge piers (e.g., Mekong Delta bridges, Ganges river bridges).

• High-rise building foundations – Driving precast concrete piles (up to 2500 mm) for skyscrapers in Mumbai, Moscow, or Hanoi.

• Temporary shoring extraction – Removing heavy H-beams after deep excavation for underground metro stations.

• Ground improvement for industrial parks – Stone column installation for liquefaction mitigation in Indonesia and the Philippines.

1. Q1: What generator size do I need for the DZ150A in India?
   A: Minimum 450 kW. For voltage fluctuations, long cable runs (over 50 m), or simultaneous crane operation, use 500–550 kW.

2. Q2: Can the DZ150A drive concrete piles of 2500 mm diameter?
   A: Yes, but you must check the concrete pile’s tensile strength and reinforcement. The 12.5 mm amplitude is suitable for most heavy precast concrete piles. For very slender piles, reduce vibration time to prevent cracking. We recommend consulting our engineering team with your pile design.

3. Q3: How do I switch between single and dual clamp on the DZ150A?
   A: The clamp system is modular. A trained technician can reconfigure it on-site in approximately 2–3 hours. Your local dealer can supply the dual clamp conversion kit.

4. Q4: Is the wireless remote control reliable in extreme cold (Russia)?
   A: Yes. The control box is rated for -30°C operation. Use lithium batteries for better performance in sub-zero temperatures. Keep the remote unit in a warm pocket when not in use.

5. Q5: What maintenance is required for the DZ150A in humid coastal sites (Vietnam)?
   A: Rinse the unit with fresh water daily after use near saltwater. Inspect the baked enamel coating for scratches and touch up immediately. Grease the vibratory case every 150–200 operating hours. Check cable insulation on the 110 mm² power cable regularly.

6. Q6: Can I use the DZ150A for pile extraction only?
   A: Absolutely. The 400 kN extraction force combined with 1387 kN exciting force will loosen even deeply driven piles. Use the remote control to reverse vibration direction. For piles stuck in dense clay or frozen ground, apply vibration for 20–30 seconds before lifting.

7. Q7: What crane brand do you recommend for the DZ150A?
   A: Any crawler crane with ≥80 t capacity – Kobelco, Hitachi, Sany, XCMG, Liebherr, or Zoomlion. Ensure the crane has a auxiliary hydraulic circuit for clamp operation (or use the electric-over-hydraulic power pack included with the hammer). The crane must also have sufficient height for the 3.3 m hammer plus pile length.

8. Q8: Does the DZ150A come with a power cable?
   A: Yes, a 110 mm² power cable is supplied. Standard length is 15–20 meters. For deeper or longer reaches, order an extension cable (maximum recommended length 50 m to avoid voltage drop).

9. Q9: What is the maximum pile length the DZ150A can handle?
   A: The hammer itself does not limit pile length – only the crane’s lifting height and the pile’s buckling resistance. With an 80 t crane and leader or long boom, you can drive piles up to 30–40 meters. For longer piles, use a larger crane or a pile gate.

10. Q10: How does the DZ150A compare to hydraulic vibratory hammers?
    A: The DZ150A offers lower operating costs (no hydraulic oil, fewer filters), lower noise (electric motor vs. diesel power pack), and simpler maintenance. However, it requires a generator of at least 450 kW. For very remote sites without grid power, a hydraulic hammer might be preferred, but the DZ150A remains more eco-friendly and cost-effective for most projects.

• Highest exciting force (1387 kN) in its weight class – beats many hydraulic hammers of similar weight.

• Lower total cost of ownership – no hydraulic oil changes, no diesel engine maintenance, only electric motor and bearing lubrication.

• Dual clamp versatility – one machine handles sheet piles, H-beams, pipe piles up to 2.5 m diameter, and heavy concrete piles.

• Global support – frequency converter and motor components available in Ho Chi Minh City, Delhi, Mumbai, and Moscow.

• Proven in extreme conditions – from tropical monsoons to Siberian winters.
