MÜLLER MS HFV-Series Vibratory Hammers
(Variable Moment)
The MÜLLER MS HFV-Series vibratory hammers are advanced free-hanging pile driving systems designed with a fully variable eccentric moment, allowing operators to precisely control vibration force throughout the driving process. By gradually increasing and decreasing the eccentric moment, these hammers significantly reduce ground vibration during start-up and shutdown while maintaining powerful driving performance during operation.
This variable moment technology provides improved control and efficiency when installing piles in sensitive environments or urban construction sites where vibration management is important. The HFV series is commonly used in crane-suspended applications and paired with dedicated hydraulic power packs for driving sheet piles, pipe piles, and structural beams in a wide range of soil conditions.
Built with Müller’s proven vibration technology and heavy-duty construction, the HFV-Series delivers high productivity, reduced resonance effects, and reliable performance on demanding foundation projects.
