The integrated rock drill and splitter, also commonly known as a combined rock drilling and splitting machine or hydraulic rock drilling and splitting machine, and referred to as a rock drilling and splitting machine in the industry, is a highly efficient attachment mounted on an excavator. It is specifically designed for breaking and demolishing rock and concrete in areas where blasting is prohibited or restricted. Its core function is to integrate the two functions of drilling and splitting, allowing for the complete “drilling-splitting” rock-breaking process without switching equipment. It is suitable for breaking hard materials such as granite, limestone, and concrete, and is widely used in mining, infrastructure construction, and demolition projects. Compared with traditional separate equipment, its work efficiency is more than 50% higher, significantly reducing equipment investment and site occupation, and it is particularly suitable for small and medium-sized construction projects.

Working Principle of the YG Integrated Rock Drill and Splitter
- Equipment Preparation: Move the integrated rock drill and splitter to the work site, level the machine body, and secure the support legs to ensure stability; connect the hydraulic oil pipes to the power source (electric or diesel), and check the sealing performance of all connections to prevent hydraulic oil leakage.
- Rock Drilling and Positioning: Start the drilling function via the control panel, adjust the drilling speed and thrust, align the alloy drill bit with the work surface, and drill at a constant speed to the preset depth (usually 500-800mm). After drilling is complete, retract the drill bit.
- Switching to Splitting: Adjust the equipment position, precisely insert the wedge-shaped splitting head into the drilled hole, ensuring that the splitting head is tightly fitted against the hole wall; switch to splitting mode via the control panel, activate the hydraulic system, and the high-pressure hydraulic oil drives the splitting head to expand, generating a huge splitting force (800-2000kN).
- Rock Splitting: The splitting force is transmitted along the rock texture, rapidly tearing the rock and breaking it into smaller pieces along the direction of the drill hole; after splitting is complete, retract the splitting head and clear the broken rock.
- Cyclic Operation: Repeat the above drilling and splitting process, breaking the rock point by point until the entire work surface is completed; during operation, the cooling device cools the equipment to prevent overheating damage.

Customers in Australia and Norway Use YG’s Integrated Drilling and Splitting Machines
Case Study 1: Granite Quarry in Queensland, Australia
- Background: This quarry needed to extract high-grade architectural cladding stone through large-scale quarrying. Traditional explosive blasting would fracture the rock mass, resulting in significant waste, and the surrounding community constantly complained about vibration and noise.
- Solution: Two large YG hydraulic rock drills and splitters were introduced and mounted on 40-ton excavators.
- Results: The equipment enabled a streamlined drilling-splitting process, producing granite blocks with intact interiors and no hidden defects, increasing the yield by over 30%. The near-silent operation completely eliminated community complaints. The quarry owner commented, “The YG drilling and splitting machine is not just a machine, but a sophisticated tool that has changed our business model. It brings quality, efficiency, and social harmony, with a return on investment far exceeding expectations.”
Case Study 2: Highway Expansion Project in the Fjords of Norway
- Background: The project required rock excavation on mountains adjacent to an existing operating highway and a fragile fjord ecosystem. Blasting was completely prohibited, and using large excavator hydraulic shears or pile breakers was too inefficient and would affect the stability of the mountain.
- Solution: Multiple YG medium-sized integrated drilling and splitting rigs were used for step-by-step static excavation.
- Results: Construction was carried out under strict control, with no flying rocks and low vibration, ensuring the absolute safety of the road below and zero disturbance to the ecological protection zone. The excavation surface was smooth, reducing the need for additional support. The project manager stated, “In such a sensitive environment, the YG equipment demonstrated the power of static technology. It allowed us to maintain considerable project progress while meeting extreme environmental requirements.”

Frequently Asked Questions about the YG Drilling and Splitting Machine
Answer: It is suitable for rocks with compressive strength ≤200MPa, including granite, limestone, concrete, etc. Different models have different splitting forces; you can choose the corresponding model according to the rock hardness to meet most engineering needs.
Answer: Absolutely. Our hydraulic rock drill and splitter is not only suitable for rocks but also for the demolition of reinforced concrete structures, such as bridges and foundations. For structures with dense reinforcement, it is recommended to use it in conjunction with an excavator hydraulic shear for cutting.
Answer: No. The integrated drill and splitting machine is a non-blasting device. Its working principle is pure hydraulic static splitting, and it does not involve the use of any explosives, so no complex blasting permit is required.
Answer: You should focus on the maximum splitting force (tonnage), drilling depth and diameter, and the flow rate and pressure of the matching hydraulic power unit. These parameters directly determine the crushing capacity and efficiency of the equipment.
Answer: The main requirements are for hydraulic flow and pressure. Generally, excavators weighing 20 tons or more are a perfect match. We will customize the hydraulic oil circuit for your integrated rock drill and splitter to ensure that it does not damage the original excavator pump.
