EH Range

APPLICATIONS

The Robi EH series of hydraulic hammers have been specifically designed to fit the most up to date and modern excavators, but have also been designed to be installed on wheel loaders and fixed boom systems. Due to the sturdiness of the Robi EH series are ideal for demolition jobs, and practically all civil engineering hammer jobs may be undertaken with this range of hammers. Bigger Robi EH series models are also suitable for production based rock breaking, and the hammers have proved to be at home with applications that involve penetrative breaking and impact breaking. All four Robi EH series models possess excellent sound suppression as standard.

KEY FEATURES AND BENEFITS

  • All Robi EH series models have a purpose built automatic lubrication system as standard, with the lubrication system ensuring longer life time for bushings and the tool shank. Proper greasing will reduce the risk of the tool failure.
  • Hammer hydraulics have been engineered to enable fixed impact energy. Thus every blow of the hammer is equally powerful, paramount feature to ensure top productivity.
  • All models possess a slim, but robust housing that employs efficient vibration damping. This housing protects the hammer hydraulic power cell from external impacts, and the vibration damping system protects the excavator boom together with its components. These features increase the working life of the breaking unit resulting in reduced cost of ownership.
