Product Overview
Built for urban demolition, interior work and noise-sensitive sites, the silenced box-type breaker wraps the power cell in sound-dampening material, reducing noise by 5–10 dB versus open-body units while protecting internals from dust and debris. Nitrogen gas-assisted with accumulator and valve integrated inside the enclosure. Part of the TGEC excavator hydraulic breakers lineup.
22 models cover 0.5–160 ton carriers, weighing 86–5580 kg with tool diameters 40–255 mm. Impact rates 70–1400 bpm, operating pressure 90–270 bar, oil flow 15–580 L/min. For comparison, the side-type breaker has a compact open frame, while the top-type open-body breaker offers maximum heat dissipation for quarry work.
Silenced Enclosure Design
The breaker runs on a nitrogen gas-assisted hydraulic impact system, fully enclosed in a sound-dampening box housing. Hydraulic pressure drives the piston down; nitrogen in the accumulator stores energy during the power stroke and assists return. Multiple sound-dampening layers and rubber isolation mounts absorb vibration and cut noise transmission. The enclosed design also protects internals from dust, debris and water.
Key benefits: reduced noise allows work in residential and commercial areas where open-body breakers would violate noise ordinances; the housing protects components and contains grease and hydraulic fluid for cleaner work areas. Trade-off: the enclosed housing dissipates heat less efficiently than open-body designs, so monitor hydraulic cooling during extended runs, and service access requires removing housing panels.

Application Scenarios
Urban building demolition: Break concrete in residential/commercial areas with noise limits. Enclosed housing cuts noise by 5–10 dB.
Interior demolition: Remove concrete walls, floors and structural elements inside buildings where noise and dust containment are critical.
Hospital, school and sensitive facility work: Demolition near noise-sensitive facilities where reduced noise is required to keep normal operations running.
Road and bridge repair in urban areas: Break asphalt and concrete pavements in city centers and residential neighborhoods with noise restrictions. Silenced design allows work during restricted hours.
Hydraulic Requirements and Carrier Matching
Flow: 15–580 L/min. Pressure: 90–270 bar. Aux circuit needs relief valve (set to max pressure), shut-off valve and rated hoses. Case drain recommended for larger models. Check nitrogen charge periodically. Enclosed housing runs hotter than open-body designs – verify excavator cooling capacity for extended use, especially in hot weather.
Select model by carrier weight range, auxiliary flow/pressure and lift capacity at working reach. Mounting brackets are custom-built per excavator make/model. Quick coupler compatible. When ordering, provide: make, model, weight, flow, pressure, pin spacing, pin diameter, stick width and coupler type if used.
Maintenance
Daily: grease tool bushing every 2–4 hours; inspect working tool and retaining pins for wear; check nitrogen charge. Weekly: inspect front head bushing (replace if clearance exceeds limit); check hydraulic hoses and through-bolt torque. Periodically remove housing panels to inspect internals, clear debris and check sound-dampening material and isolation mounts.
Full service – seals, piston, valve, accumulator, bushings – every 500–1000 hours depending on duty. TGEC stocks full spare parts for all silenced box-type models: seal kits, pistons, front heads, valve assemblies, accumulators, through-bolts, bushings, retaining pins, hoses and housing components. Accepts all four standard hydraulic breaker chisel types: moil point, blunt tool, flat wedge and conical point, 40–255 mm diameters.
