Product Introduction: TF Series Mining Rock Drilling Platforms

1. Core Features & Advantages
2. Multi-functional & wide application range
   The TF series includes two core models (TF-12L, TF-14L), suitable for roadway excavation, bolt support, water detection and blasting drilling. Compatible with metal mines, coal mines and tunnel projects, it matches various rock drill heads to meet diverse drilling requirements.
3. Stable hydraulic mechanical transmission & strong climbing capacity
   Equipped with 66kW main engine and 55kW independent pump station, featuring stepless speed adjustment of 0–15km/h and maximum 14° climbing ability. It runs stably on inclined and uneven underground roads with sufficient power reserve for heavy-duty operation.
4. Optional multiple drill heads with full aperture coverage
   Supports three independent rotary rock drills (A180D/L, A22D, S20D/L) and multiple shank specifications including R32, T38 and T45. The drilling diameter ranges from 33mm to 76mm, adapting to soft, medium and hard rock formations.
5. High-impact drilling for high efficiency & quality holes
   The drill head delivers 18–22kW impact power with high impact frequency and sufficient pressure. Adjustable rotary torque ensures fast drilling speed and regular hole walls, effectively avoiding hole deviation and collapse.
6. Precise feeding system with high operation stability
   The standard thrust force reaches 15kN with uniform feeding and stable drilling force. Reasonable turning radius prevents wall scratching during tunnel turning, perfectly adapting to narrow roadways with small and medium sections.
7. Standard lubrication system for long service life
   Equipped with a professional pneumatic lubrication system to continuously lubricate drill bits, rods and core components, reducing wear and high-temperature loss, lowering failure rate and extending equipment service life.
8. Modular design for easy transportation & maintenance
   Modular assembly structure enables quick disassembly and assembly, reducing cross-border logistics costs. Standardized and interchangeable vulnerable parts simplify spare parts procurement and on-site maintenance for overseas mining projects.
9. Integrated operation for significant cost reduction
   Integrates walking, rock drilling and support drilling functions. A single machine completes full-process construction without auxiliary equipment, replacing traditional manual drilling, reducing labor intensity and greatly improving roadway construction efficiency.
10. Product Introduction

The TF series mining rock drilling rigs consist of two standard models: TF-12L and TF-14L. They are professional drilling equipment specially developed for mine roadway excavation, tunnel construction and underground bolt support drilling, widely used in domestic and foreign metal mines, coal mines and tunnel engineering projects.

Adopting diesel hydraulic mechanical transmission, the machine is equipped with a 66kW main engine and a 55kW independent hydraulic pump station, delivering stable power and flexible mobility. The walking speed is adjustable from 0 to 15km/h with a maximum climbing capacity of 14°, ensuring stable operation on complex underground road surfaces. The TF-12L has a total feed beam length of 5315mm and a maximum drilling depth of 3355mm; the TF-14L has a total feed beam length of 6158mm and a maximum drilling depth of 3960mm, covering shallow and deep hole drilling demands. With a constant thrust of 15kN and scientific turning radius design, the machine avoids tunnel wall abrasion during steering. Weighing about 14 tons with adjustable body height, it adapts to various roadway sections.

The equipment supports three optional independent rotary rock drill heads, matching multiple shank specifications to achieve a full drilling diameter range of 33–76mm. With impact power of 18–22kW, high impact frequency and adjustable rotary torque, it performs stably and efficiently in various rock formations. The standard pneumatic lubrication system continuously maintains core drilling components, reducing wear and ensuring long-term continuous operation stability.

Integrated with walking, precise rock drilling and support drilling functions, the machine independently completes roadway excavation, blasting hole and bolt support hole construction without auxiliary equipment. The modular structure facilitates disassembly and transshipment, cutting cross-border logistics costs. Standardized core parts simplify overseas maintenance. Replacing traditional manual drilling operations, it effectively reduces underground labor intensity and improves the standardization and efficiency of roadway drilling construction, serving as core high-efficiency equipment for mine and tunnel engineering.
