Indonesia’s booming mining sector demands robust machinery capable of handling high-density formations. Recently, a major contractor in Indonesia faced a severe bottleneck at a coastal nickel mine development and infrastructure site. The project required massive, efficient rock breaking, but traditional drilling-and-blasting methods were strictly prohibited due to nearby environmental protections and strict local safety regulations.
Seeking an open-pit, non-explosive alternative that wouldn’t compromise on daily output, the client partnered with YG Machinery. We delivered a high-performance hydraulic rock drill and splitter tailored to their heavy excavator setup, transforming their hard rock excavation into a highly profitable, seamless operation.

Project Background & Strict Site Constraints
The project site presented a challenging mix of high-density granite and hard rock layers overlying nickel ore deposits. The contractor needed to clear thousands of tons of rock daily to establish infrastructure roads and reach the ore veins. However, the site came with strict operational hurdles:
- No Explosives Allowed: Proximity to coastal infrastructure and ecological zones meant standard blasting was legally ruled out.
- Traditional Hammers Failed: Conventional hydraulic breakers were too slow, causing excessive tool wear and consuming too much fuel without meeting the required daily tonnage.
- Vibration & Noise Limits: The proximity to structural foundations required a method that eliminated destructive shockwaves.
The Client’s Strict Selection Logic
The Indonesian buyer did not simply choose our machinery by chance; they conducted a rigorous procurement evaluation. They evaluated multiple options, including imported expanding grouts, independent large-scale crawler rigs, and standard attachment hammers.
The client’s primary procurement logic focused on operational integration. They realized that using a separate drilling rig followed by a standalone splitter would double their labor costs and slow down production moving between holes. They specifically searched for a system that could handle both processes on a single platform. YG’s integrated rock drill and splitter emerged as the ideal choice because it mounts directly onto their existing heavy excavator fleet, eliminating the need for secondary moving platforms and maximizing their return on investment.
Strategic Equipment Matching & Field Limitations
To balance their technical needs with the reality of the site’s geology, we matched the client with our specialized excavator rock drill and splitter line. The equipment parameters were precisely calculated to overcome their specific field limitations:
- Excavator Match: Designed to seamlessly integrate with their heavy excavators rated above 25 tons.
- Drilling Precision: Equipped with a heavy-duty hydraulic rock drill with a 22KW power output , delivering a drilling speed of up to 1.0 meter per minute directly through granite.
- Extreme Splitting Force: Features a massive splitting force of 8,000 tons, allowing the operator to crack open massive rock structures cleanly from an open face without any flying debris.
Delivery, Commissioning, and Real-World Feedback
YG managed the entire export process, ensuring the machinery arrived smoothly at the Indonesian port and was safely transported directly to the mine site. Our engineering team provided comprehensive remote commissioning guidance and digital operation training for the local crew.
The field feedback has been outstanding. In high-density granite, the integrated rock drill and splitter achieved a single-hole total cycle time (drilling + splitting) of just 3 to 4 minutes. The machine maintained a consistent production output of 100 tons per hour. Because high-density granite naturally cracks cleanly along its crystalline structure under high hydraulic force, the client reported that some cracks successfully extended up to 8 meters in length, vastly outperforming their initial field estimates.
Why This Indonesia Case Matters to Global Buyers
For mine operators and infrastructure contractors worldwide, this project serves as a proven blueprint. It proves that you do not need to rely on complex explosive permits or slow, costly hydraulic hammers to handle hard rock excavation. By utilizing an excavator rock drill and splitter , you can convert your existing excavator into a complete, self-contained rock-quarrying factory, maintaining high production output while remaining fully compliant with modern environmental laws.
YG’s Hydraulic Rock Drill and Splitter Features
Our heavy-duty rock extraction attachments are engineered for the toughest industrial environments, combining drilling and splitting into one robust platform.
- True One-Platform Integration: The single-beam design houses both the high-speed hydraulic rock drill and the high-tonnage splitter. The operator can switch from drilling to splitting in seconds without leaving the excavator cabin.
- Massive Industrial Force: Driven by advanced hydraulic boosters, the system delivers an incredible 8,000-ton splitting force, cracking open hard formations effortlessly.
- Dust-Free & Eco-Friendly Design: Integrated with an on-board industrial vacuum dust collector featuring an 8-element filtration system, protecting operators and keeping your job site clean and compliant.
- Flexible Operational Control: Features a 120-degree rotation angle and a 30-point digital wireless remote control system, allowing precise positioning even in restricted mining benches or deep infrastructure trenches.
Excavator Rock Drill and Splitter Applications
Beyond nickel mining, this heavy attachment series is highly adaptable across various global industrial sectors:
- Open-Pit Mining: Ideal for extracting nickel, gold, copper, and iron ore where blasting is restricted or unfeasible.
