APT Hammers and Breakers combine flexibility with hard-hitting power. The MH11 pick hammer is designed for horizontal work in renovation, demolition, and structural alterations, while the MH 55 (medium-weight) and MH 70 (heavy-duty) multipurpose breakers are ideal for road building and maintenance on asphalt, brickwork, frozen soil, or concrete.
Features:
- Slim design for excellent line of sight to the working tool
- Quick-release couplings for fast connections
- No external side bolts or protruding parts
- High-back pressure (HBP) models can be operated from the PTO outlet of most skid steers
- Vibration-reduced (A) models offer the same breaking performance with additional operator comfort
