Product Overview
The M‑Series is TGEC's mid‑range fully‑hydraulic breaker, designed for everyday demolition, road construction, utility work, and medium rock breaking on excavators from 10 to 32 tons. Like all TGEC gas‑free breakers, it runs entirely on hydraulic pressure – no nitrogen gas, no charging, no gas seals to fail. The fully‑hydraulic valve handles both the power and return strokes, which simplifies maintenance and keeps performance consistent no matter the temperature or altitude. Part of the TGEC excavator gas‑free hydraulic breakers lineup.
Five models cover carriers from 10 to 32 tons, with service weights from 750 to 1650 kg and tool diameters from 100 to 140 mm. Impact rates range from 320 to 840 bpm depending on the model and flow, with operating pressure from 140 to 180 bar and oil flow from 80 to 170 L/min. The M‑Series is aimed at contractors who need a solid, low‑maintenance breaker for daily demolition and construction work – a good balance of impact energy, smooth operation, and no nitrogen charging or gas-pressure maintenance. For a compact‑profile breaker, check the R‑Series (20‑40 ton machines); for heavy‑duty jobs, the V‑Series covers 18‑120 ton carriers.
Balanced Fully-Hydraulic Performance
The M‑Series is designed to operate across its specified hydraulic flow range, allowing impact frequency to vary according to model and hydraulic input. This gives contractors a balanced mix of impact energy and frequency across the carrier range, suitable for materials from asphalt and friable concrete to medium‑hard rock. The fully‑hydraulic valve manages piston timing throughout the cycle, keeping operation smooth and consistent across different working conditions.
The fully‑hydraulic setup delivers smooth, consistent impact delivery. The hydraulic valve controls piston motion precisely throughout the cycle, reducing harsh impact spikes. Rubber isolation mounts between the power cell and housing help reduce vibration transmission to the excavator, improving operator comfort on long runs and reducing wear on the boom and stick.

Application Scenarios
General building demolition: Break slabs, foundations, walls, and structural elements in commercial and residential demolition.
Road and bridge work: Tear up asphalt pavement, concrete road surfaces, and bridge decks for repairs and replacement.
Utility and trenching: Break rock, hardpan, and concrete obstructions in utility trenches, pipeline work, and foundation digging.
Medium rock breaking: Fragment boulders and rock layers in quarry secondary breaking, site prep, and landscaping rock removal.
Hydraulic Requirements and Carrier Matching
Getting the hydraulics right is key to getting the most out of your M‑Series breaker. Each model has specific flow requirements from 80 to 170 L/min, with operating pressure from 140 to 180 bar. The auxiliary circuit needs a properly sized relief valve set to the breaker's max pressure, a shut‑off valve to isolate it when not in use, and hoses rated for the pressure. A case drain is recommended to keep back pressure from damaging the valve assembly and seals. Make sure your excavator's hydraulic cooling system can handle the extra load, especially if you're running in hot weather or doing continuous work.
When picking an M‑Series model, check that your excavator's weight falls within the carrier range, that your auxiliary flow is within the breaker's spec, and that your circuit can deliver the required pressure. Also verify that your machine's lift capacity can handle the breaker's service weight at the reach you'll be working at. Mounting brackets are custom‑built for each excavator make and model – quick coupler compatibility is available for both mechanical and hydraulic systems. When ordering, give us the excavator make and model, operating weight, auxiliary flow and pressure, pin‑to‑pin spacing, pin diameter, stick width, and coupler type if you're using one.
Maintenance
The M‑Series is simpler to maintain than traditional nitrogen‑charged breakers because there's no gas system to deal with – no charging, no pressure checks, no gas seals. Daily maintenance: grease the tool bushing every two to four hours with good breaker grease, and inspect the working tool and retaining pins for wear or damage. Check the front head bushing weekly and replace it when clearance exceeds the limit. Keep an eye on hydraulic hoses for leaks or chafing, and check through‑bolt torque periodically. Full service – seal replacement, piston inspection, valve overhaul, and bushing replacement – is recommended every 500‑1000 hours depending on how hard you're running it. Any qualified hydraulic tech can do this work without special breaker tools or nitrogen charging gear. TGEC stocks a full range of spare parts for all M‑Series models. The M‑Series works with all four standard hydraulic breaker chisel types: moil point, blunt tool, flat wedge, and conical point.
