HMC Movax Sonic Side Grip Range

The SP-50, SP-80, and SP-100 Sonic Side Grip Vibratory Pile Drivers from HMC Movax are excavator-mounted attachments with articulating side grip that speeds up the pile driving process on any job site.

Manufactured in the U.S.A., the Sonic Side Grip uses an excavator’s hydraulics to safely and quickly pick up, unload, place, drive and extract piling.

This innovative pile driver is designed to overcome obstacles such as low overhead clearance and narrow passageways, as well as eliminate the need for peripheral equipment to be used in the piling operation.

The Sonic Side Grip range from HMC can handle pile up to 50′ long, H-beams, pipe pile and wood pile. There is a model to suit every application.

RPI Construction Equipment is the only company in the USA with HMC Movax Sonic SideGrip® equipment available for rent.
