MS HFB SG Side Grip Vibratory Hammers
(Fixed Moment)

The MÜLLER MS HFB SG series side grip vibratory hammers are compact excavator-mounted piling attachments designed for efficient sheet pile installation in confined or restricted jobsite conditions. Featuring a fixed eccentric moment vibration system and a powerful side-grip clamping mechanism, these hammers allow contractors to pick, pitch, and drive sheet piles directly with the excavator without the need for a crane.

The side grip design enables the operator to grab sheet piles directly from the ground, rotate them into position, and drive them in a single operation. This significantly improves installation efficiency on smaller projects, urban jobsites, and temporary works where mobility and speed are critical. The MS HFB SG hammers combine reliable MÜLLER vibration technology with robust clamping force, providing consistent driving performance across a wide range of soil conditions.
