U135 Series Roadheader Picks / Tunneling Picks

The U135 Series is a high-performance hard rock-grade pick specifically designed for high-power roadheaders, suitable for high-intensity underground roadway and tunnel excavation operations.

Matched with high-power roadheader bits for tunneling construction in underground coal mine roadways and engineering tunnels

Suitable for heavy to ultra-heavy working conditions, including complex rock formation conditions such as hard rock, high corrosion, and fault fracture zones

Feat. & Ben.

1.High wear-resistant hard rock grade performance: The alloy tip and tooth body are treated with special processes, featuring extremely high wear resistance, suitable for continuous tunneling in full rock roadways

2.Strong penetration and corrosion resistance: Optimized tooth design with excellent penetration, suitable for corrosive formations and fault fracture zones

3.High impact resistance and high temperature resistance: Structurally reinforced with superior impact resistance and resistance to high temperature sparks, suitable for high-intensity continuous operations

4.Quick replacement design: Reasonable structure with convenient disassembly and assembly, reducing downtime and improving construction continuity
