Project Overview
In early 2024, a mining contractor in Chile needed a more controlled way to excavate hard granite. Manual rock breaking was labor-intensive, while conventional blasting was not suitable for every part of the project.
The contractor selected YG’s YG1500 Hydraulic Rock Drill and Splitter, mounted on a 40-ton excavator, to combine drilling and hydraulic rock splitting in one machine.
Project Challenges
The contractor needed to:
- Break hard granite with better control over rock fragmentation.
- Reduce manual breaking and reliance on conventional blasting where appropriate.
- Simplify equipment handling and improve excavation efficiency.
- Work at different angles to accommodate site conditions.

Solution:YG1500 Hydraulic Rock Drill and Splitter
The YG1500 integrates rock drilling and hydraulic splitting, allowing the operator to drill a hole and then split the rock without switching between separate drilling and splitting machines.
Its key features include:
- Integrated operation: Combines drilling and splitting to simplify the work process.
- Controlled rock breaking: Hole placement and splitting sequences help guide fragmentation, although results depend on rock joints, hardness, and drilling layout.
- Multi-angle operation: Supports drilling and splitting at different angles to suit varied excavation conditions.
- Two-stage hydraulic splitting: Designed to deliver high splitting force for hard-rock applications.
- Wireless remote control: Allows the operator to control the machine remotely from a suitable operating position.
For outdoor quarry work, the equipment can also be paired with a suitable air compressor to support pneumatic drilling functions.

Chile Project Performance
The Chile customer reported positive feedback on the equipment’s operation and its suitability for hard-rock excavation.
Based on the validated performance figures provided for the equipment, the YG1500 can achieve:
- Rock output of approximately 1,000–3,000 tons per day, depending on rock conditions, work sequence, and operating hours.
- Up to 4 times the efficiency of a traditional hydraulic breaker under comparable, suitable working conditions.
- Lower fuel consumption than a traditional breaker at comparable output, subject to the specific machine configuration and operating conditions.
These figures should be treated as performance benchmarks rather than guaranteed results for every site. Actual output and fuel consumption depend on rock hardness, fracture patterns, drilling layout, excavator configuration, and operator experience.
Our integrated rock drilling and splitting machine has also received positive feedback from customers in Southeast Asia. See our rock drilling and splitting machine project in the Philippines for another real-world application.

Hydraulic Rock Drill and Splitter Applications

The YG1500 Hydraulic Rock Drill and Splitter can be considered for:
- Granite and other hard-rock excavation
- Quarry and mining operations
- Selected tunnel excavation projects
- Foundation excavation in hard rock
- Sites where conventional blasting is restricted or unsuitable
For projects that already have drilled holes and only require rock splitting, see our Hydraulic Rock Splitter Machine.
