Multi-Rope Friction mine hoist/winch liner with High Performance
To fulfill the new requirement of large and super - large multi - rope friction hoist , our company using the Germany imported raw materials produces GDM326 high performance friction liner with imported material, mainly matching the imported hoist, domestic large and super large hoist and meeting other needs.
Compared with other liner, GDM326 high performance friction liner with imported material has been greatly improved in the friction coefficient, compression resistance, abrasion resistance, stability etc., so it has been adopted and trusted by a great number of users and brought good economic benefit. GDM326 high performance friction liner with imported material can also be used for other machinery conveying power by friction and be used as leading wheel friction liner of funicular.
Technical Characteristics
1. All the friction coefficients of GDM326 in various conditions are more than 0.28, which completely fulfills the requirements of multi - rope friction hoist.
Friction coefficients of GDM326 are listed in below table:
