Model 100 Hydraulic Rock Breaker (chisel diameter:100mm) fits 10–15 ton excavators, available in open-side triangle type and silent box type. With oil-nitrogen drive & built-in main valve, it delivers strong impact, low failure rate and fuel-saving durability, a mainstream medium breaker for earthwork and demolition.

1. MSGB100 Side Type Hydraulic Breaker comes with 100mm chisel diameter, perfectly compatible with all brands of 10–15 ton excavators. Adopting Korean-style built-in main valve & oil-nitrogen hybrid system, it is a bestselling side-type rock hammer for global municipal demolition, road breaking and quarry secondary crushing. Different from fully enclosed silent box breaker, its low side-mount design delivers superior performance in narrow foundation pit and wall-side trenching jobs with balanced striking power & lightweight body, solving buyers’ top worry of mismatched model and limited working space on site
2. To resolve global buyers’ common buyer concerns: cheap breakers crack piston/cylinder easily, leak oil under high temperature and fail quickly during continuous hard rock breaking, MSGB100 core components including piston, cylinder and bushings are forged from 42CrMo alloy steel with full vacuum quenching heat treatment in line with Korean & Japanese OEM standard. CNC precision machining keeps tight matching clearance to avoid cylinder pulling and oil leakage even under long-hour granite & reinforced concrete demolition. Built-in large-volume accumulator absorbs hydraulic pulse fluctuation, stabilizes consistent blow energy to prevent unstable striking force, cutting unexpected downtime and maintenance loss effectively
3. Standard equipped with quenched high-manganese 42CrMo chisel, available in point, blunt and moil point for rock, concrete and frozen ground with longer wear life than ordinary cast chisel. All wear parts including seal kit, bushing, chisel and nitrogen charging tools are in permanent stock for global fast delivery, saving buyers long lead time and high aftermarket part markup. Optional auto-grease system automatically feeds lubricant to cut manual maintenance and extend service life of bushings & chisels
4. Widely applied in European & American municipal building demolition, asphalt pavement breaking, foundation excavation; Southeast Asia quarry secondary crushing & river reef clearance; Middle East earthwork and frozen soil breaking, realizing multi-scene utilization to improve equipment ROI
