Plasma Coating Reinforcement Technology No Sparking High Impact
High Toughness U47 Series Roadheader Pick Bits
U47 series roadheader pick (bits)
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!
Advantages of LENO U47 series roadheader picks:
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.
