Used with U47 series picks;
Innovative design to effectively protect the pick;
The surface hardness of the pick base is higher than that of products of the same level;
High-end alloy steel material to ensure excellent performance;
Can be customized according to requirements;
The pick base is used as a supporting tool for the pick, and is installed on the roadheader and shearer together with the accessory pick bushing. During the working process, the pick can bear the external load from coal, rock, inclusions, etc. One of the vulnerable parts of coal falling. The base of LENO U47 picks perfectly matches the U47 picks. The production process is checked layer by layer. The domestic first-line alloy steel material is used to ensure the high quality and high quality of the products. Its surface hardness is higher than that of products of the same level! The surface of the pick base is smooth and flat, without visible cracks, dents, etc., and has been rust-proofed before leaving the factory, so it will not rust for long-term storage.
Carbide head selection range 16mm-29mm;
Supporting roadheader head and coal mining machine;
No sparks, safer;
High strength, fatigue resistance, long life;
Efficient cutting, improve work efficiency;
Suitable for medium-duty conditions and heavy-duty conditions.
The pick of the roadheader is the main cutting on the cutting head of the roadheader. It is installed on the cutter head in cooperation with the pick base and is a vulnerable part of roadway tunneling. The quality of the bits of the roadheader is directly related to the high efficiency of the roadheader operation, power consumption, production capacity, continuity, and functional working life.
LENO Plasma Technology Application Department is a professional manufacturer of high-end picks and rodent traps. The pick production equipment is currently the most advanced welding and quenching integrated production line in China. The production is controlled by the middle level, which ensures the high standard price of LENO picks!
