MÜLLER MS HFB S Excavator Vibratory Hammers

The MÜLLER MS HFB S series is a compact and efficient line of excavator-mounted vibratory hammers designed for strong performance in a streamlined package. Built with proven Müller engineering, the HFB S models deliver reliable vibration output, optimized hydraulic demand, and excellent maneuverability for confined and urban job sites.

Models including the MS-4 HFB S, MS-6 HFB S, and MS-7 HFB S provide strong centrifugal force and consistent amplitude while maintaining a balanced weight profile for mid-size excavators. This allows contractors to achieve high productivity without moving into heavier hammer classes.

When paired with MÜLLER MSU clamp systems, the HFB S series offers a versatile solution for driving and extracting sheet piles, casings, and beams across a wide range of soil conditions.
