Weighing 4200kg, with a 240L/min flow rate, a 5.5-cm splitting gap, and 4-times higher efficiency than a breaker hammer. Behind these figures lies the YG excavator mounted rock drill and splitter, built for maximum efficiency in hard rock mining. The excavator-mounted rock drill and splitter combines precise drilling from a rock drill with the powerful thrust of a splitter, delivering high efficiency and safe operation. It handles jobs without free faces as well as upside-down drilling for rock breaking with ease.
Working Principle of Excavator-mounted Rock Drill and Splitter
This hydraulic rock drill and splitter runs in four simple steps, all controlled by one person via remote control:
Step 1: Position the drill point. The excavator boom moves the drill-splitter module to the target rock face. The concentrated weight design keeps the unit stable even when the boom is fully extended. Remote control allows accurate alignment of the drilling position.
Step 2: Hydraulic drilling. The rock-drilling module with Swedish-engineered technology works with alloy drill bits at a feed rate of 800-1000 mm per minute. A matched screw air compressor blows out rock dust at the same time to keep holes clean.
Step 3: Insert the wedge into the hole. Once drilling finishes, switch to splitting mode. An Italian hydraulic booster system drives the two stage cylinder to push the splitting wedge into the borehole.
Step 4: Hydraulic rock splitting. The two stage cylinders apply pressure together to produce a splitting force of up to 160 KN. Cracks expand upward from the hole bottom to a maximum gap of 5.5 cm, breaking the rock completely from its base.

6 Reasons to Choose the YG Rock Drilling and Splitting Machine
Swedish rock drilling technology: The patented drill frame has a simple, stable structure with precise positioning. Drill bits deliver a far longer service life than competing products.
Italian hydraulic booster system: Dual-stage splitting cylinders offer boosted pressure for high rock output and fast splitting performance on extra-hard rock.
Imported splitting wedge material: Solves complex foundation-construction challenges including multi-angle work, slopes and irregular cross-sections.
Wireless remote control: A single operator works from a safe distance away from the working zone for greatly improved safety.
Optimized centre of gravity design: Machine weight concentrates behind the horse head and on the stick to prevent forward tipping. It can fit mini excavators starting from 20 tons.
High-efficiency-dust-removal system: Equipped with China’s advanced screw air compressor. It runs quietly with a compact footprint for energy saving, dust free construction.
What Working Conditions Suit the Excavator-mounted Rock Drill and Splitter?
Open-pit mining for extra-hard rock: Breaks granite, basalt, and other rock with hardness f=6-20. No blasting permit is required for operation. Tunnel excavation: Drilling and splitting work on tunnel faces for mountain, highway, and railway tunnels.
Municipal projects: Low-vibration, low-noise hard-rock breaking for city road and pipeline works without disturbing residents or nearby buildings.
Metro construction: Compact size allows lifting and lowering into shafts, ideal for confined underground spaces.
High-slope mountain work: Supports multi-angle drilling and splitting, including vertical, inclined, and upside-down positions for rough terrain.
Defence and emergency projects: Special jobs for military facilities requiring quiet, low visibility construction.
Q1: What is the minimum excavator tonnage required?
The YG-130 model fits a minimum 20 ton excavator. The optimized gravity design guarantees stable operation on smaller excavators with no extra counterweight needed.
Q2: How deep does the hole need to be for splitting?
The YG-130 reaches a maximum drilling depth of 1900 mm, while the YG-152 goes up to 2300 mm. Both models meet the splitting depth requirements for most rock types.
Q3: How strong is the splitting force? What rock hardness can it break?
The two stage cylinder delivers a maximum splitting thrust of 160 KN with a 5.5-cm crack width. It works for rock rated f=6-20, such as granite and basalt.
Q4: How much faster is it than a traditional breaker hammer?
Under equal site conditions, the rock drilling and splitting machine works 4 times faster than standard breaker hammers and causes less wear on the excavator boom.
Q5: Does the job produce dust and loud noise?
The matched screw air compressor removes rock dust during drilling for clean operation. Hydraulic power creates far less noise than blasting or breakers, suitable for urban and populated areas.
Q6: Can the machine work at different angles?
Fully supported. The excavator-mounted rock drill and splitter drills and splits accurately at vertical, horizontal, inclined, and even upside-down angles to handle all complex site conditions.
