MÜLLER MS HFB Excavator Vibratory Hammers

The MÜLLER MS HFB series is a line of high-performance excavator-mounted vibratory hammers engineered for efficient sheet pile installation and extraction across a wide range of soil conditions. Designed with proven German engineering, the HFB series combines compact design, high centrifugal force, and optimized hydraulic efficiency to deliver reliable performance on both small and large job sites.

Available in multiple models from MS-1 through MS-17, the HFB range covers carrier classes from compact excavators to heavy-duty machines, offering scalable solutions for trench shoring, temporary works, marine construction, and foundation support applications.

Each hammer is built with a rugged eccentric system, delivering consistent amplitude and vibration output while maintaining low overall weight for improved carrier compatibility and maneuverability. When paired with MÜLLER clamp systems (MSU series), the MS HFB becomes a versatile and highly productive attachment for driving and extracting sheet piles, casings, and beams.
