The YO series jack hammer rock drill achieves a perfect balance between low air pressure startup and high impact power output by optimizing the pneumatic structure and piston stroke design. This ensures excellent drilling speed and extremely low overall operating costs in various complex working conditions.
Mining sites: The YO series is the main rock drill machine for mining sites, especially suitable for the mining operations of marble, granite, and other rocks. In mining sites, it is mainly used for drilling blasting holes to prepare for subsequent blasting mining.
Tunnel excavation: This method is applicable to the drilling and blasting construction of transportation tunnels and water conservancy tunnels. YO20 is particularly suitable for rock drilling operations in large-scale tunnel projects and performs exceptionally well in drilling and blasting boreholes.
Building drilling: The YO series is not only suitable for natural rocks but can also be used for drilling operations on concrete buildings, for projects such as building renovation and reinforcement.
All-round handheld drilling: Without the need for an air leg, The YO series can be used as a handheld rock drill, enabling all-round (horizontal, vertical, inclined, downward) rock drilling operations,such as road and railway subgrade excavation and slope treatment.
Application: Main model for quarries, small mines, and construction projects.
Drilling Diameter: 36-42 mm
Drilling Depth: 1.5-2 meters
Machine Weight: 18 kg - Lightweight and flexible, easy to operate.
Impact Energy: ≥22 J - Performs well on hard rocks.
Core Advantages: Low gas consumption (<1.2 m³/min), low noise, particularly suitable for use with small-sized air compressors, and is an economical and efficient model.
Application: Suitable for large-scale mines and tunnel excavation, designed for long-term and high-intensity operations.
Drilling Diameter: 34 - 42 mm
Drilling Depth: Up to 5 meters - Stronger deep-hole drilling capability.
Machine Weight: 20 kg
Impact Energy: ≥ 26 J - Greater impact energy, enhancing rock-breaking speed.
Core Advantages: Longer piston stroke, higher impact frequency, suitable for drilling deep-hole blasting holes in large and medium-sized mines and tunnel projects.
Optimized pneumatic system
Utilizing precisely manufactured cylinder and piston components (cylinder diameter 58-63mm), it can output a powerful impact energy at an air pressure of 4.9×10⁵ Pa. Compared to traditional models, the air consumption is reduced by 10%-15%, significantly saving energy costs.
Extremely strong rock adaptability
Whether it is medium-hard rock with a force of 6 or hard granite with a force of 20, the YO series can maintain a stable drilling speed and ensure the construction progress.
Modular supporting solution
It can perfectly fit the FT100 type pneumatic leg (with a propulsion length of 810mm) and the FY200 type oil injector. The pneumatic leg has a sturdy structure and stable support; the oil injector automatically supplies oil, effectively prolonging the lifespan of internal components of the machine head and reducing the frequency of maintenance.
Reliability in harsh environments
The key components are made of wear-resistant alloy materials, which can withstand the high dust and high humidity conditions in mines. The entire machine has a long service life and the spare parts are highly versatile, significantly reducing the post-sale maintenance costs for customers.
The efficient operation of the rock drill cannot be achieved without a stable power source. Not only do we provide the main unit, but we also offer you the best power matching suggestions:
Air compressor accessories
For YO18 and YO20, we recommend the following air compressors for matching (such as the W-3.0/5 type diesel piston air compressor).
Drilling tool consumables
We provide original drill rods (B22×108mm specification) and ball-end/flat-end/straight-end drill bits to ensure a perfect match from power to drilling tools, maximizing drilling efficiency.
