APPLICATIONS

Robi mini-series hydraulic hammers are designed to be a perfect match with modern mini excavators, small skid steer loaders and demolition robots. They have proved to be ideal for the demolition of light concrete structures, walls, floors and ceilings. In such applications they have proved their worth in breaking asphalt, frozen or compact ground, and additionally, digging spaces for cables and small scale pipe lines can be undertaken with these agile, yet highly productive machines. Also available with sound suppressing housing (C-model).

KEY FEATURES AND BENEFITS

  • The hammers are designed for effective penetrative breaking, with the high impact frequency of each model ensuring superior productivity in every size class, in any suitable application.
  • Hammer hydraulics are designed to accept the sufficient oil flow in every carrier weight class with no extra valves or flow restrictors being required. This ensures installation is easy and results in a longer working life for the hammer.
  • Excellent hydraulic efficiency reduces fuel consumption, thus reducing the total cost of operation and ownership
  • City model available with silenced housing (read more)
  • Available also with side plates (read more)
