The roadheader pick is the main cutting tool on the cutting head (gun head) of the roadheader. It is installed on the cutting head in cooperation with the pick base and is one of the vulnerable parts of roadway driving. The quality of the picks of the roadheader is directly related to the efficiency of the roadheader operation, the power consumption, the production capacity, the stability of the work and the service life of the supporting parts.
LENO Plasma Technology Application Department is a professional high-end pick cutter research and development manufacturer. The pick production equipment is currently the most advanced automatic brazing and quenching integrated production line in China. The production process is checked at various levels to ensure the high standard and high quality of LENO series picks!
LENO U135 series roadheader picks are hard rock-grade picks, which are suitable for heavy-duty working conditions-super heavy-duty working conditions. The imported tungsten carbide wear layer is used to further enhance the wear resistance of the product and increase the service life of the product; adopts standards The design of the main body and the wide flange shoulder provides great protection for the tooth seat, which greatly improves the service life of the tooth seat; using insulating material, no sparks are generated when the pick is cut, and the construction operation is safer; the surface of the product is smooth and flat. There are no visible cracks, dents, etc. The product has been rust-proofed before leaving the factory, and it will not rust for long-term storage. The LENO U135 series picks can be used not only in the excavation of roadways, but also in the excavation of engineering tunnels due to their strong impact resistance and permeability.
Adopt clever design to increase the strength of the product;
Absorb the tungsten carbide wear-resistant layer to further improve the wear resistance of the product and increase the service life of the product;
The standard tooth shoulder design tooth seat provides great protection so that the life of the tooth seat can also be improved;
The products are produced with special materials and manufacturing processes, no sparks are generated during pick cutting, and the production operation is safer;
The surface of the product is clean and smooth, without visible traces, dents, etc. The original anti-rust treatment of the product prevents rust for a long time.

Super-hard rock picks can be used in F10 super-hard rock formations
Tunnel teeth effectively impact 120MPa hard rock roadway/large section tunnel rock formation
The cemented carbide we use is made of tungsten carbide and cobalt. Expensive raw materials ensure the best sintering ability and help us make pick tools with high hardness and wear resistance. This pick can withstand a very Strong shock load.
Leno leading wear-resistant coating technology allows every pick to have a high degree of wear resistance. In the application, the spin design of the pick will play a huge role in ensuring the uniform wear of the product and extending the life.
Wear-resistant pick cutters have a complete range of models and provide cutting solutions for multiple main application fields, multiple complex geological environments, and multiple mining machinery and equipment.
