1.Under various working conditions, the friction coefficient of GDM326 friction liner is greater than 0.28, which fully meets the requirements of multi-rope friction hoist. 2.It has high mechanical properties, no harmful material to damage the wire rope, and it is easy to process the rope groove on site.

In order to meet the domestic new demand on large-scale, ultra-large multi-rope friction hoist, our plant introduced raw materials from Germany to produce GDM326 high-performance friction pad, for supporting import and domestic large-scale, ultra-large hoists and for meeting the needs of different users.
