Darda Splitters

400 tons of splitting force in one hand!


  • Enormous splitting force up to 413 tons
  • Dust free and near silent operation
  • Vibration free
  • Light weigh

Splitting Cylinders are handheld demolition devices, which controllably split material with the use of hydraulic pressure. Above all they convince, when larger conventional demolition devices are ruled-out because they produce dust, flying debris, vibrations, noise and possibily exhaust fumes.
