MS HFBV SG / SGX Side Grip Vibratory Hammers
(Variable Moment)

The MÜLLER MS HFBV SG series side grip vibratory hammers are advanced excavator-mounted piling attachments designed for efficient sheet pile installation with reduced vibration during start-up and shutdown. Featuring a variable eccentric moment vibration system, these hammers allow operators to gradually increase vibration force, minimizing ground disturbance and improving control when working near sensitive structures or in urban environments.

The side grip clamping system enables the excavator to pick, pitch, position, and drive sheet piles in a single operation, eliminating the need for a crane on many projects. This makes the HFBV SG series ideal for contractors working on shoring systems, seawalls, cofferdams, and temporary works where mobility, efficiency, and vibration control are critical.
Built with the proven durability of MÜLLER vibration technology, the HFBV SG hammers provide powerful driving performance while offering improved operational flexibility and reduced resonance during operation.
