1 .The friction coefficient under various conditions were greater than 0.*5 (by the China Coal Mine and Luoyang Mining Machinery Engineering Design and Research Institute measured were greater than 0.*8 or more), fully meeting the multi-rope friction hoist application requirements.
2. High mechanical strength, without material damaging steel wire rope, easy on-site processing of groove. Its mechanical properties are as follows:

Tested contrast, heat-resistant and melt-resistant of liner are better than K*5 imported, which is very favorable in the stability and wear resistance in use.
3. Good compatibility of friction grease. applied to imported, domestic friction grease, with domestic LZM friction grease better.
4. The price is moderate (*0% of unit price of the K*5, *7% of K*5 density). cost performance is better than imported pads, which can bring considerable economic benefits for the users.
In summary, GM*3 high performance friction pad compared to other pads, is very different mainly in the friction coefficient, hardness, compressive strength, heat resistance, wear resistance and stability, so it can replace imported pads. The product has been widely adopted by users, and has achieved good economic performance
