Product Overview
The R‑Series is TGEC's compact‑profile fully‑hydraulic breaker, designed for construction, demolition, and site work on 20‑ to 40‑ton excavators. Like all TGEC gas‑free breakers, it runs entirely on hydraulic pressure – no nitrogen gas, no charging, no gas seals. The fully‑hydraulic valve handles both strokes, which simplifies maintenance and keeps performance consistent across temperature and altitude changes. That's a real advantage for contractors working across multiple sites with varying conditions. Part of the TGEC excavator gas‑free hydraulic breakers lineup.
Four models cover carriers from 20 to 40 tons, with operating weights from 320 to 410 kg and tool diameters from 70 to 85 mm. Impact rates range from 440 to 990 bpm depending on the model and flow, with operating pressure from 120 to 125 bar and oil flow from 30 to 100 L/min. The R‑Series is for contractors who want a reliable, low‑maintenance breaker for everyday demolition and construction – good performance, smooth operation, and no nitrogen charging or gas-pressure maintenance. For more power, check the mid‑size M‑Series (10‑32 ton machines) or the heavy‑duty V‑Series (18‑120 ton carriers).
Compact Fully-Hydraulic Design
The R‑Series packs a fully‑hydraulic impact system into a compact package. A precision hydraulic valve shuttles high‑pressure oil between the upper and lower piston chambers, driving the piston through both strokes with hydraulic force alone – no nitrogen gas assist, no gas chamber, no charge valve, no gas seals. The compact profile keeps the breaker nimble in tight spots like building foundations, utility trenches, and confined job sites.
Key design features: low overall height improves visibility and fits under overhead restrictions. Rubber isolation mounts between the power cell and housing cut vibration to the excavator, making the operator's day more comfortable and extending boom and stick life. The fully‑hydraulic system delivers smooth, consistent impacts – the hydraulic valve controls piston motion precisely, reducing harsh shock loads to the carrier.

Application Scenarios
General construction and site work: Break footings, remove rock from excavation, break hardpan, and prep ground for foundations.
Building demolition: Bust slabs, foundations, walls, and structural elements. The compact profile fits tight spaces.
Road and utility work: Break asphalt, concrete, and rock in road repair, utility trenches, and pipeline jobs. Gas‑free design simplifies maintenance across multiple sites.
Landscaping and site prep: Remove rock, break up hard ground, and prep areas for drainage and development.
Hydraulic Requirements and Carrier Matching
Flow: 30–100 L/min depending on model. Pressure: 120–125 bar operating, relief at 180 bar. Aux circuit needs relief valve set to spec, shut‑off valve, and rated hoses. Case drain recommended – max back pressure 10 bar. The gas‑free design means no nitrogen checks, but make sure your excavator's cooling system can handle the extra load, especially in hot weather.
When picking a model, verify carrier weight range, auxiliary flow, and lift capacity at working reach. Mounting brackets are custom‑built per make/model; quick coupler compatible. Order with: 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 tool and retaining pins for wear. Check front head bushing weekly – replace if clearance exceeds limit. Inspect hoses and through‑bolt torque. No nitrogen checks – one less thing to worry about.
Full service – seals, piston, valve, bushings – every 500‑1000 hours depending on duty. Any qualified hydraulic tech can handle it; no special breaker tools or nitrogen gear needed. TGEC stocks full spare parts for all R‑Series models. Accepts all four standard hydraulic breaker chisel types: moil point, blunt tool, flat wedge, and conical point, 70–85 mm diameters.
