YO type rock drill

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.

Suitable groups

YO18:Suitable for small and medium-sized quarries, small mines, individual construction teams or building renovation projects. Its core advantages lie in its portability, low energy consumption, affordable price, and it is the top choice for handheld operation scenarios.

YO20:Suitable for large and medium-sized mines, tunnel construction companies, and projects with high-intensity continuous operations. Its higher impact energy and optimized heat dissipation can ensure the progress of critical schedules. It is the preferred choice for professional teams that pursue ultimate production efficiency and equipment stability.

 

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.
