Quzhou Zhongdu Machinery Technology Co., Ltd. is one of the leading yo18 mini portable air powered pneumatic rock drill machine manufacturers and suppliers in China. Welcome to wholesale high quality machines made in China here from our factory. Contact us for customized service.
Products Description
The yo18 rock drill is a simple jack hammer, and it is forged from high-strength alloy steel and undergoes precise machining and surface hardening treatment, endowing it with outstanding wear resistance and impact resistance. Its rugged industrial lines are complemented by an anti-slip textured grip area, balancing professional aesthetics with operational safety. The integrated compact design optimizes weight distribution while maintaining core power, making it more suitable for prolonged handheld operation.The core advantage of this air powered pneumatic rock drill lies in its innovative integrated power system, which optimally matches the impact frequency with the energy output. Compared to traditional models, it reduces energy consumption by approximately 15% and increases drilling efficiency by nearly 20%. It is particularly suitable for high-intensity continuous operation scenarios.

applications
Open-pit mine bench drilling
Vertical or inclined drilling is carried out on the open-pit mining working face for blasting hole construction. The simple jack hamer is suitable for various rock layers and can drill to a depth of 3-5 meters, providing standard channels for subsequent charging and blasting.
Emergency rescue passage excavation
In the emergency rescue of mine accidents, the yo18 rock drill, with its rapid start-up and high reliability, can quickly excavate rescue passages or ventilation holes. Its compact design is suitable for operations in narrow spaces, and its powerful power can cope with complex rock layers after collapse, securing precious time for life rescue.
Geological exploration sampling drilling
The mini rock drill machine can be used to drill rock core samples. Its adjustable impact frequency can meet the sampling requirements of different hardness rock layers, ensuring the acquisition of complete and clearly structured rock cores, providing reliable first-hand data for geological analysis and vein assessment.
Products quality control
1.Raw material control
The yo18 rock drill using special alloy steel and high-strength composite materials, all materials undergo multiple inspections such as spectral analysis and hardness testing before being stored, ensuring the durability of the products from the very beginning.
2.Process precision management
The core components are manufactured using a CNC machining center. Throughout the process, online monitoring of dimensional tolerances is implemented. The assembly accuracy error of the impact system is controlled within ±0.01mm.
3.Performance testing system
After each portable jack hammer is assembled, it undergoes a continuous 72-hour load test, with key data such as impact energy and frequency stability being recorded in real time. The unit can only be released from the factory if it meets the standards.
