- Most powerful hammer in class: bigger and heavier eccentric weights, 15% higher productivity than traditional vibratory hammers
- Centered double eccentric weights for better durability of bearings
- Transverse cushion array minimizes the chance of bending of hammer and piles
- Auto Tilt: 90° tilt and 360° hydraulic rotation, “Auto Hold” function in the 90° position, no failure-prone tilt cylinders
- Side grip pile drivers: no auxiliary extended arm required, hydraulic revolving mounting adapter (360°) with hydraulic tilt ±30°; a single excavator operator, no ground crew needed
- Low maintenance cost: concise structure of components, longer durability
