1.Working Conditions & Key Data

2.Field Performance

• The trial delivered a total advance of 43.4 m under demanding rock-cutting conditions.
• Our picks consumed 12 pcs in total, while competitor picks consumed 57 pcs.
• Based on on-site consumption, our pick usage was only about 21% of the competitor level, representing roughly 79% lower consumption.
• Pick consumption per meter of advance was about 0.28 pcs/m for our picks, versus about 1.31 pcs/m for competitor picks.
• Even in the high-wear zone, the picks showed better wear resistance and stronger suitability for continuous operation.

3.Product Advantages

• Strong wear resistance: Performs reliably in f=11 limestone and fractured rock conditions.
• Better performance in high-wear zones: Helps reduce replacement frequency in the most demanding positions.
• Less downtime: Fewer pick changes help increase effective roadheader operating time.
• Lower cost per meter: Reduced pick consumption leads to better overall operating economy.
• Good field compatibility: Easy to use with existing equipment and mixed on-site operating conditions.

4.Summary

Under XCMG EBZ280 operation with a 280 kW cutting motor, 54 r/min speed, and water cooling, the J60/79/76/38-40MF pick completed 43.4 m of advance in f=11 limestone and fractured formations. Our picks consumed 12 pcs versus 57 pcs for the competitor, demonstrating lower consumption, stronger wear resistance, and better cost efficiency per meter in high-wear tunneling applications.
