Features

The U95 pick has a smooth and flat surface appearance. There are no cracks in the weld area and the bonding surface between the solder and the base material. The tooth shoulder is petal - shaped. It is suitable for medium - and heavy - duty working conditions in mining areas with rock and relatively complex geological conditions. The S135 pick is a dedicated roadheader pick, a hard - rock - grade pick, suitable for extremely hard and highly corrosive rock conditions. It can effectively cut rocks of grade 9 to 14, such as sandstone and quartzite. In addition, this pick features resistance to high - temperature sparks, high - speed wear resistance, and rapid replacement.

Application

The mining pick is one of the vulnerable parts in coal mining and roadway excavation machinery, and it is the main tool for coal winning and coal crushing. The pick body is mostly made of steel grades such as 42CrMo and 35CrMnSi. The hardness of the pick body is 40 - 45HRC, and the impact toughness is not less than 49J/cm². When the pick is working, it bears high - cycle compressive stress, shear stress, and impact load.

The models of coal picks are roughly divided into: S series and U series.
