Type: KM15-1860 
1. Product details: Anchorage in Coal Mine is a kind of machine that can be tensioned and can be installed on the exposed end, mainly used in the Coal Mining, roadway. After tensioned and preloaded, pass the tenssion to the supporting surface, maintain the roadway safe. Especially used in the engineering of prestressing tensioning construction for mines, tunnels, bridges. 
2. Parameters:

15.24mm, 15.20mm 
Resistance intensity adapt for steel strand 
≤ 1860MPa 
The coefficient of efficiency η 
≥ 95% 
Total strain stress length of assembly parts εapu 
≥ 2.0% 
Weight 
0.5kg 
Execution standard

3. Features: 
Anchor piece tooth's shape is reasonable, damage the surface of anchor lightly, seize the rope firmly. Anchor piece has 3 disc, and it is bevel, the direction of turning is opposite to the steel strand, so it can allot the tensile force which from the steel strand well, the anchor piece can follow up efficient. High coefficient of efficiency, support safely and reliably. 
4. Packaging: 
Kraft paper carton packing, Contains 25 sets of anchorage, Each anchorage packaged by plastic bags independently.
