U170 Pick

Dulbert has invested significant effort in the research, development, and production of cutting picks. From the material selection stage, it demonstrates distinctiveness. The alloy head of its cutting picks is made from imported, custom-designed high-strength tungsten-cobalt alloy, which offers exceptional hardness and wear resistance, providing a solid foundation for stable performance under harsh working conditions. To handle rock formations of varying hardness, Dulbert has developed multiple types of cutting picks to meet practical needs. For softer F3 rock formations, the standard cutting pick performs excellently. It ensures cost-effectiveness while effectively tackling the excavation of such rock layers, enabling precise rock breaking and supporting efficient operations. When dealing with harder rock formations like F10–F12, the reinforced cutting pick becomes a popular choice. The reinforced pick features a sturdier structural design, with an optimized connection process between the alloy head and the pick body, allowing it to withstand greater impact forces. This ensures stable operation during high-intensity rock cutting, significantly enhancing the pick’s durability and reliability. This meticulous development of pick types based on different rock characteristics enables Dulbert cutting picks to adapt to various complex working conditions while maintaining outstanding performance.

In terms of manufacturing processes, Dulbert has introduced advanced CNC machining technology, which greatly improves the fitting accuracy between the pick holder and the cutting pick. During actual operation, the precise fit between the pick and the holder reduces shaking, effectively lowering the risk of shank breakage and extending the pick’s service life. Moreover, Dulbert has independently developed an embedded deep fusion process, adding a robust wear-resistant layer to the pick’s surface to further enhance its wear resistance and impact resistance. Additionally, to better protect the pick holder, Dulbert has applied an alloy composite coating to the holder, preventing wear and ensuring the overall performance of the cutting pick.

Dulbert cutting picks have demonstrated remarkable advantages in practical applications. In the excavation of F13 rock layers in Shanxi coal mines, other brands of cutting picks required replacement every 2 hours on average, while Dulbert picks, thanks to their excellent performance, could operate continuously for over 6 hours. In a Sichuan tunnel project involving F10 rock layers, other brands needed replacement every 1 meter of tunneling, requiring about 5–6 picks, whereas Dulbert picks could advance 1.6 meters before replacement. These real-world cases clearly reflect the outstanding performance of Dulbert cutting picks in terms of wear resistance and impact resistance. It is precisely these advantages that have quickly earned Dulbert cutting picks widespread market recognition.

In addition to cutting picks, Dulbert also excels in the field of connecting links. In industries such as mining and power chemical conveying systems, connecting links are critical components for chain connections, and their performance directly affects the operational efficiency and safety of the entire system. Dulbert connecting links are made from high-strength alloy steel and undergo strict heat treatment processes to ensure excellent wear resistance and impact resistance. During production, CNC machining technology is used to achieve precise dimensional control and tolerance management for each connecting link, guaranteeing high reliability and consistency.

Dulbert offers a diverse range of connecting link types to meet the needs of various application scenarios. The vertical connecting link, with its simple structure and easy installation, is primarily used for vertical connections, offering high stability and is widely applied in conveying systems in the coal mining industry. The arc-tooth link features a unique curved tooth design that forms an angle with the chain’s tensile direction, effectively preventing chain loosening and detachment. It is suitable for various complex working conditions, particularly excelling in heavy-duty transportation and high-intensity operations. The saw-tooth link, with a tooth design resembling a saw blade, ensures tight engagement with the chain, reducing slippage and loosening. It can be installed horizontally or vertically and is commonly used in equipment such as scraper conveyors, transfer machines, and slag removal machines, offering advantages like easy installation, low maintenance costs, and high tensile and impact resistance.
