Hammer & Breakers

APT hammers and breakers combine flexibility with hard-hitting power. The MH 11 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
