Construction excavator Hydraulic breaker box type

Enstruc Silenced Hydraulic Breakers for 12-50 tonne excavators deliver controlled, high-impact breaking power with reduced noise and vibration. Designed for civil, demolition, and utility applications, these box-type breakers provide reliable performance on small to medium size machines where sound reduction, carrier protection, and consistent impact energy are critical to productivity on busy work sites.

Key Features

  • Noise-damped box housing for quieter operation in urban and regulated areas
  • Strong impact force for reinforced concrete, rock excavation, and demolition tasks
  • Low-vibration design helps protect machine hydraulics and operator comfort
  • Enclosed frame helps contain dust and debris for cleaner jobsite operation
  • High-strength body and wear components suited to heavy daily use
  • Stable impact frequency for efficient material fracture and removal
  • Designed for excavators up to 50 tonnes for civil and infrastructure projects
  • Supplied complete with gas charging unit, hoses, and chisel tool sets
