Product Overview
In traditional hard‑rock work, you’d need a drill rig to open the hole and then a separate splitter to crack the material. The TGEC integrated unit merges those two jobs onto one excavator—no switching machines, no wasted time. A single operator, working from a wireless remote, positions the drill, bores the hole, swings the splitter head into place, and drives the wedge to break the rock along a clean, controlled line.
The attachment replaces the bucket and runs off the auxiliary hydraulic circuit. An onboard full‑hydraulic air compressor delivers air for dust control and hole cleaning, while a load‑sensing electro‑hydraulic system automatically adjusts drill feed, rotation speed, and splitting force. Both the main frame and the splitter head rotate a full 360 degrees without limit, so you can tackle vertical walls, overhead surfaces, and sloped faces without moving the carrier. The dust suppression system uses air‑pressure balanced jet technology to capture dust at the source with no added power draw. As part of the TGEC excavator rock drill and splitter family, three sizes cover the full mid‑to‑large excavator spectrum.

Series-Wide Technical Highlights
Integrated drill‑and‑split design lets one excavator do both jobs, eliminating the need for separate drilling and splitting equipment.
Unrestricted 360‑degree rotation on both the main frame and splitter head means you can drill and split on vertical, overhead, and angled surfaces without repositioning the machine.
Wireless remote control enables a single operator to run the excavator, drill, and air compressor from a safe distance, reducing exposure to debris.
Non‑destructive dust removal uses air‑pressure balanced jet technology to capture dust at the source with no extra energy consumption.
Automatic displacement compensation adjusts splitting force continuously during the wedge stroke, maintaining steady pressure as the rock fractures.
Rolled integrated reinforced frame with adjustable height adapts to various working heights and ground conditions across all three models.
Excavator Compatibility Guidance
TGEC integrated rock drill and splitter models are sized for excavators from 20 to 50 tons. The TG-RDS115 is built for 20‑ton carriers, the TG-RDS130 fits 30‑ to 36‑ton machines, and the TG-RDS152 handles 30‑ to 50‑ton excavators. Every unit needs an auxiliary hydraulic circuit that can deliver adequate flow and pressure to run the drill, splitter, and onboard air compressor simultaneously. Required flow ranges from 210 to 280 L/min depending on the model, while air compressor displacement falls between 15 and 21 m³/min.
Final fit depends on the excavator's auxiliary hydraulic capacity, mounting bracket geometry, and pin dimensions. The machine's lift capacity at the working reach must accommodate the attachment weight (3.2 to 4.85 tons) plus the expected drilling and splitting loads. When placing an order, provide the excavator make and model, operating weight, auxiliary hydraulic flow and pressure, pin‑to‑pin spacing, and pin diameter. The TGEC engineering team will confirm the correct model and supply a custom mounting bracket matched to your machine. If you use a quick coupler, we can also design the bracket to fit that interface. For a complete selection guide, see How to Choose an Excavator Rock Drill and Splitter for Hard Rock Excavation.
Typical Applications
Quarrying and dimension stone: Drill and split large blocks in granite, marble and limestone quarries without blasting, preserving stone grain quality and reducing waste from explosive fracture.
Mining and underground excavation: Break hard ore and rock in tunnel headings where blasting is restricted by ventilation, ground control or proximity to existing structures.
Tunneling and shaft sinking: Process rock in confined environments where breaker vibration and noise must be minimized, and where controlled fracture direction is critical for tunnel profile.
Demolition and foundation work: Split reinforced rock, concrete foundations and bedrock during building demolition, basement excavation and site preparation in urban areas.
Non-blasting rock excavation: Process hard rock near pipelines, utilities, buildings and environmentally sensitive zones where blasting is prohibited or heavily restricted.
Road and railway construction: Split rock cuts, trench rock and slope stabilization material in right-of-way construction where controlled breaking reduces flyrock and vibration.

Working Principle
The integrated drill‑splitter runs through a straightforward four‑step sequence: position and drill the hole to depth while onboard air clears cuttings, retract and rotate the main frame 180 degrees to bring the splitter head into line, ｉｎｓｅｒｔ the wedge and apply hydraulic force to expand the counter‑wedges and break the rock, then retract and move on to the next hole. An automatic displacement compensation valve keeps splitting pressure steady as the rock fractures, and dual 360‑degree rotation lets you work vertical, overhead, and angled faces without repositioning the excavator.

Wear Parts & Service Support
The main wear components are the drill steel and bit, the splitter wedge and counter‑wedges, the pivot pins and bushings at the rotation joints, and the hydraulic hoses that flex across the rotating frame. Inspect the drill steel and bit after each shift for wear, cracking, or thread damage. Check wedges regularly for chipping and deformation—worn wedges reduce splitting efficiency and can cause uneven fracture. Grease the rotation bearings according to the maintenance schedule and inspect hoses for abrasion or leaks. The onboard air compressor needs periodic filter changes and oil level checks, and the dust removal nozzles should be cleaned regularly to maintain effective suppression. With routine care, the system delivers dependable performance in the most demanding rock conditions.
