Hydraulic Breaker Hammer Assembly is the powerhouse we attach to excavators or skid steers to smash rock and concrete. We hook it up to our machine’s hydraulic system so oil pressure drives a piston back and forth, hitting the tool bit hundreds of times a minute. It has a sturdy steel housing, valve system and mounting brackets so it stays put while working hard. We grease it, check seals and swap worn parts to keep it singing, not rattling, like a jackhammer on steroids.
