Hydraulic Hammers

Demoter Hydraulic Hammers are made in Italy and feature the very latest technology in Hammer design.

Monoblock Body

  • Breakers are monoblock design – increases power and reduces maintenance
  • No tie rods to re-tension or break in the Demoter

N2 Energy System

  • Nitrogen inertial energy recovery powers breakers
  • Increases power of breaker and reduces stresses on arm of carrier

No Diaphragm

  • Unique design of nitrogen accumulator works without need for a diaphragm
  • Increases power over diaphragm breakers by 30%
  • Lowers maintenance costs

Extended Nitrogen Charge

  • New range of Demoter breakers uses new type of sealing system on a floating support
  • Increases charge life by 300%

Silenced

  • Monoblock construction is quiet by design
  • Dampening material inside body results in extremely low working noise levels

Visibility

  • Streamlined design of breakers allows excellent visibility when working close to walls
