Socomec DMS Series · Monoblock Silenced Architecture
Socomec DMS Monoblock Silenced Series (135 to 1,630 lbs)
- ✓ Monoblock structure eliminates traditional tie-rod side bolts, totally removing the primary cause of breaker downtime and catastrophic failure.
- ✓ The hydraulic accumulator acts as the top sealing cap, fastened with standard screws to allow immediate access to all bushings and the piston upon removal.
- ✓ Internal monoblock assembly is vulcanized into the external casing using an acoustic polyurethane compound, slashing jobsite noise and isolating the excavator boom from damaging micro-vibrations.
- ✓ Long stepped-section piston design maximizes kinetic energy transfer directly to the tool while significantly attenuating mechanical recoil into the breaker housing.
- ✓ Integrated modular hydraulic brake detects lack of rock resistance and automatically bypasses fluid to eliminate destructive blank firing.
- ✓ Pressure-stabilizing distributor valve maintains uniform operational pressure and energy output regardless of fluctuations in hydraulic flow, keeping impact energy within 80% even when supply falls below minimum spec.
- ✓ Advanced multi-seal package with heavy-duty lower dust wipers permits seamless underwater demolition and underground mining applications.
