Heavy-Duty Electric Pile Driver DZ120A – Low-Noise Operation & Wireless Remote Control for Steel Pipe and Concrete Piles

The DZ120A Electric Vibratory Hammer is a powerful, mid-range piling solution from the DZ Series, designed for contractors who need higher output than the DZ90A without moving to the largest models. Suspended from crawler cranes (minimum 70 t capacity), this machine excels at both pile driving and extraction in challenging soil conditions.

The DZ120A handles a wide variety of pile types: steel sheet piles (retaining walls, cofferdams), I-beams, H-sections, steel pipe piles (up to 1200 mm diameter), precast concrete piles (square or round, up to 1200 mm), and stone columns for ground improvement. Its dual clamp option (single/dual selectable) provides flexibility for different pile shapes and sizes – a key advantage for rental fleets and multi-project contractors in Vietnam, India, and Russia.

• Eco-Friendly & Low-Noise Operation
  Significantly reduces noise pollution compared to diesel hammers. Perfect for urban construction in Ho Chi Minh City, Mumbai, or Moscow, where noise restrictions are strictly enforced.

• High-Grade Vibration-Resistant Motor
  A 120 kW leading domestic brand motor delivers stable, long-lasting performance under continuous high-intensity vibration. The motor is designed to operate reliably in Russian sub-zero temperatures (with appropriate cold-weather grease) and 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 exceptional rust resistance – critical for coastal projects in Vietnam and India (e.g., port foundations, seawalls).

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

• Single/Dual Clamp Type
  The DZ120A supports both single and dual clamp configurations. Use single clamp for standard sheet piles and H-beams; switch to dual clamp for larger diameter steel pipe piles or concrete piles to ensure secure gripping.

• High Amplitude (12.2 mm)
  Ideal for denser soils and precast concrete piles. The higher amplitude helps penetrate stiff clay or sandy gravel common in Indian and Russian sites.

The DZ120A bridges the gap between the DZ90A (5.58 t) and larger DZ135A (8.8 t to 9.5 t? DZ135A weight 9520 kg, but DZ120A is 8800 kg).

• Cofferdams for river bridges – Driving steel sheet piles in Vietnam’s Mekong Delta or India’s Ganges.

• Port and harbor foundations – Installing steel pipe piles (up to 1200 mm) in Chennai or Vladivostok.

• Precast concrete pile driving – Square or round piles for high-rise foundations in Moscow or Mumbai (ensure amplitude matches pile stiffness).

• Temporary shoring extraction – Removing H-beams after deep excavation in soft Bangkok clay.

• Ground improvement – Stone column installation for liquefaction mitigation in Indonesia.

Q1: What generator size do I need for the DZ120A in India?
A: Minimum 350 kW. For voltage fluctuations or long cable runs (over 50 m), use 400–450 kW.

Q2: Can the DZ120A drive precast concrete piles of 1200 mm diameter?
A: Yes, but check the pile’s tensile strength. The 12.2 mm amplitude is suitable for most concrete piles. For very long or slender piles, reduce vibration time to avoid cracking.

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

Q4: Is the wireless remote control reliable in cold Russian winters?
A: Yes. The control box is rated for -30°C operation. Keep batteries warm; use lithium batteries for better performance in extreme cold.

Q5: What maintenance is required for the DZ120A 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 as needed. Grease the vibratory case every 200 operating hours.

Q6: Can I use the DZ120A for pile extraction only?
A: Absolutely. The 400 kN extraction force combined with 786 kN exciting force will loosen most driven piles. Use the remote control to reverse vibration direction.

Q7: What crane brand do you recommend?
A: Any crawler crane with ≥70 t capacity – Kobelco, Hitachi, Sany, XCMG, or Liebherr. Ensure the crane has a auxiliary hydraulic circuit for clamp operation (or use the electric-over-hydraulic power pack included with the hammer).

Q8: Does the DZ120A come with a cable?
A: Yes, 95 mm² power cable is supplied. Length is typically 15–20 meters. For longer reaches, order an extension cable.

• Best power-to-weight ratio in its class (120 kW / 8.8 t = 13.6 kW/t) – more efficient than many hydraulic vibratory hammers.

• Lower operating costs – no hydraulic oil changes, fewer moving parts, lower fuel consumption (electric vs. diesel).

• Dual clamp versatility – one machine handles sheet piles, H-beams, pipe piles, and concrete piles.

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