VIBRO HAMMER S-Series
MOST VERSATILITY
BULLSTERN SIDE GRIP VIBRO HAMMER can handle, pitch and drive the sheet and tube piles. It is capable to accomplish the whole pile driving process without need of manual handling of the piles or assisting machinery – especially when limited space, head room or access is available.
KEY BENEFITS
- DESIGNED FOR MANY TYPES OF PILES & BEAMS
- 2 JAWS OPENING FOR MORE AGILITY
- ENHENCED CLAMPING FORCE BY ACCUMULATOR
- 360-DEGREE ROTATION / ±30-DEGREE TILTING

BULLSTERN Side Grip – Secure Grip, Strong Performance
1. High-Stability Clamping System
The Side Grip uses a dual-cylinder clamping structure with independent load-holding check valves, ensuring a secure grip even under high-frequency vibration. This stable clamping performance minimizes slippage and increases vibration transfer efficiency during pile driving.
2. Optimized Grip Force Distribution
The jaw geometry is engineered to distribute load evenly along the pile surface, helping maintain alignment and reducing stress concentrations during driving or extraction. This contributes to smooth handling and consistent penetration rates.
3. Durable Structure for Heavy-Duty Operation
All major load-bearing components—arms, bushings, pins, and clamping interfaces—are built with precision machining and high-hardness heat treatment, providing strong resistance to wear and deformation under repetitive loading.
4. Efficient Vibration Delivery
Although BULLSTERN Side Grip is not a resonance-free system, its rigid frame and stable clamping force support effective energy transfer from the hammer to the pile. This results in reliable driving performance across mixed or moderately dense soil conditions.
5. Flexible Pile Positioning Capability
The ±30° tilt function enables pile installation in offset or angled positions without repositioning the excavator. Integrated hydraulic protection prevents unintended drift, keeping the pile stable throughout the driving process.
