S Series Roadheader Picks

Roadheader picks are mainly used for roadway excavation in coal or semi-coal roadways and soft rock, and can also be used in tunnel construction such as railways, highways, and water conservancy projects.

At present, roadheaders mainly use pick picks, which are generally brazed by alloy steel teeth and hard alloy cutter heads. Its performance depends on the material of the pool body, the performance of the cemented carbide and the quality of the brazed joint. The degree of wear of the pick depends mainly on the hardness and corrosiveness of the coal rock.

S series picks are used for roadheaders, including S100, S120, S135, S150, S160, S170, etc.

In nature, S Series Roadheader Picks are high-efficiency conical cutting tools, characterized by a lightweight body structure, standardized quick-connect shank and optimized cutting tip geometry-key supports for their flexible operational performance. The streamlined conical tip design is specially adjusted for small-power equipment, which can effectively improve stratum penetration while reducing energy consumption, ensuring efficient cutting even under limited power output. Most models are equipped with self-adaptive wear balancing technology, which can automatically adjust the rotation speed according to stratum hardness, ensuring uniform wear of the tip and body during intermittent cutting operations, avoiding local excessive wear and extending the service cycle by 25%-40% compared with conventional picks for small roadheaders. For the pick body, high-quality 35CrMnSi alloy steel is selected, and precision forging combined with vacuum heat treatment processes is adopted to achieve a perfect balance between strength and toughness. The finished products have a hardness of 38-45 HRC and an impact toughness of not less than 52 J/cm², fully meeting the technical standards for small and medium-power roadheader picks and laying a solid foundation for their stable performance in complex formations.

Compared with similar products in the market, S Series Roadheader Picks have distinct competitive advantages, mainly reflected in four core aspects.

• High cutting efficiency & low energy consumption: the optimized tip geometry and lightweight body design are perfectly matched with small and medium-power roadheaders, reducing cutting resistance by 15%-20% and effectively saving equipment energy consumption while improving excavation efficiency.
• Excellent flexible adaptability: the product series fully covers soft to medium-hard formations, and each model is fine-tuned for specific stratum characteristics, ensuring stable cutting performance in loose, broken and uneven stratum conditions.
• Easy installation & low maintenance cost: the quick-connect shank design is compatible with most small and medium-power roadheader models at home and abroad, enabling one-person quick replacement without professional tools, significantly reducing equipment downtime.
• Outstanding cost-performance ratio: on the premise of ensuring core performance, the optimized manufacturing process reduces production costs, and the long service life and low failure rate further lower the comprehensive construction cost, bringing obvious economic benefits to small and medium-sized projects.

The S Series Roadheader Picks cover a complete range of models, which are classified according to stratum softness and roadheader power specifications, with clear positioning for each model. Core models include S100, S120, S135 and S150, all of which adopt standardized quick-connect shanks to ensure good compatibility with mainstream small and medium-power roadheaders and facilitate daily replacement and maintenance, further enhancing the series' operational convenience advantage.

• S100 is an entry-level model for soft formation excavation, with the core advantage of lightweight and high efficiency. It is suitable for cutting loose coal seams and argillaceous sandstone, and is widely used in coal mine auxiliary roadway construction.
• S120 is a general-purpose model for medium-soft formations, featuring a balanced combination of wear resistance and cutting fluency, and is applicable to municipal pipeline tunnels and shallow tunnel excavation projects.
• S135 is optimized for medium-hard formations mixed with fine gangue; its enhanced tip welding process and surface treatment effectively resist gangue impact and reduce tip wear, highlighting the advantage of strong anti-interference in complex formations.
• S150 is a high-performance model for medium-hard weathered rock excavation, equipped with a thickened tip and reinforced body structure, which can withstand intermittent impact during rock cutting and avoid body deformation, making up for the defect of poor load-bearing capacity of ordinary small roadheader picks.

The S Series Roadheader Picks are mainly applied in excavation scenarios equipped with small and medium-power roadheaders, covering coal mine auxiliary roadways, municipal pipeline tunnels, urban subway auxiliary projects and small non-coal mine excavation projects-their application scope is closely combined with the series' advantages of flexible adaptability and high cost-performance ratio.

In coal mine auxiliary roadways, the series shows excellent adaptability to loose coal seams and soft rock roadways: S100 and S120 models (with high efficiency and low energy consumption advantages) can efficiently complete auxiliary roadway excavation while reducing equipment load; S135 models cope with medium-hard gangue-containing roadways, ensuring construction fluency.

In municipal pipeline tunnels (such as water supply and drainage pipelines and gas pipelines), the S Series Roadheader Picks, with their small size and flexible cutting performance, can adapt to narrow construction spaces and ensure accurate excavation.

In urban subway auxiliary projects and small non-coal mine excavation, the series' cost-performance advantage and easy maintenance characteristics significantly reduce project investment.

A practical application case in a municipal pipeline tunnel project in Changsha, Hunan Province, China, fully verifies the product advantages of the S Series Roadheader Picks. This project mainly excavates medium-soft argillaceous sandstone tunnels with a diameter of 2.5 meters, and the original conventional picks had problems such as low cutting efficiency, frequent tip wear and high replacement frequency, which seriously affected the construction progress and increased the project cost. After switching to S Series Roadheader Picks (mainly S120 and S135 models), the advantages of the series were fully demonstrated: the average daily excavation progress was increased by 30%, the pick consumption per unit length was reduced by 35%, the average service life of a single pick was extended by 60%, and the downtime caused by pick replacement was reduced by nearly 55%. The comprehensive construction cost was significantly lowered, fully proving the series' remarkable practical value and economic benefits in small and medium-sized excavation projects.

The S Series Roadheader Picks further optimize the operational experience with their humanized design advantages. All models adopt standardized quick-connect shanks and matching pick sleeves, which can be disassembled and replaced in 2-3 minutes without professional tools, greatly improving construction efficiency.
