The LH92 conical pick is a professional high-strength mining tool designed for extreme and complex underground geological conditions. As a robust shearer pick and core accessory for tunneling machine, it is specially optimized for mining areas filled with massive gangue and hard rock, overcoming the defects of ordinary picks such as easy abrasion, fracture and low cutting efficiency in harsh working environments.
Adopting integrated forging technology and high-hardness tungsten carbide alloy head, this pick features outstanding high wear resistance and strong impact resistance. Its scientific cone-shaped structural design disperses cutting pressure effectively, ensuring stable cutting performance when crushing hard rock and gangue mixed strata. Strict heat treatment processing further enhances its structural toughness, greatly extending the service life in high-load mining operations.
Perfectly compatible with coal shearers and tunnel excavation equipment, the LH92 pick is a dedicated heavy-duty pick for tough coal mining and tunneling projects. It significantly reduces tool replacement frequency, cuts down equipment maintenance costs, and improves overall mining continuity and working efficiency. With superior durability and reliable adaptability to gangue-rich and rocky strata, it has become an essential wear-resistant accessory for modern complex mining operations.
