multi rope friction hoist Friction liner Elevator polyurethane products
Mine hoist spare parts
Elevator polyurethane products
The company can produce all kinds of polyurethane products used for mine hoist.
1,Polyurethane friction pad: under the condition of coated with special friction grease for wire rope, the friction coefficient is greater than 0.20, which is in line with the special technical conditions of friction lining of general multi rope friction hoist;
2,The polyurethane cage guide wheel of mine hoist (Guan Er), the strength and wear resistance are greatly higher than that of rubber products;
3, Single rope winding mine hoist, ground multi rope friction hoist hand pad, tower type multi rope friction hoist guide wheel liner service life is 3-5 times higher than the general PVC liner;
4, Various elastic couplings of polyurethane elastomer;
5, The leading wheel liner, polyurethane and other tugboat polyurethane elastomer parts.
Friction liner is the key part of the multi rope friction hoist. Its performance directly affects the performance parameters, the lifting capacity and the safety reliability of the hoist.
Friction liner material through the process of polyvinyl chloride, polyurethane, polyurethane, thermosetting materials. The first three materials design friction coefficient in 0.2 ~ 0.23, after a more than 0.25 (i.e. high friction pad).
High friction liner is divided into domestic high friction, imported materials to suppress high friction, pure imported high friction three, the user can choose according to the needs of. Tower hoist pad is a rope groove, floor type hoist pad two rope grooves, mainly for the turning rope groove is convenient, corresponding also improved the liner service life and the use of liner material. The fixing block and the pressing block are fixed on the friction wheel through bolts.
In order to meet the domestic large multi rope friction hoist machine new requirements, our factory production of raw materials used in Germany imported GDM326 material high performance friction liner, supporting the main imported hoist and domestic large hoist and meet the needs of different users.
GDM326 imported materials with high performance friction liner compared with other liners, mainly in the friction coefficient, compression, wear resistance and stability, and so on by the larger increase, so it can be trusted. Has been a large number of users, have achieved good economic benefits. GDM326 imported materials with high performance friction lining can also be applied to other mechanical properties which can be used for friction transmission power, and can be used as the main wheel friction lining for cable car.
Main features of high performance friction pad for GDM326 imported materials:
1 The production of raw materials in Germany: BakeliteAG company's production of resin, Ghemetall friction materials and LANXESS company's rubber raw materials production of high-performance friction liner;
2 With a high and stable friction coefficient: the friction coefficient of friction in the coating is greater than 0.28 (test report 0.33). Fully meet the requirements of the use of multi rope friction hoist;
3 Low wear and high mechanical properties;
4 Has good flame retardant properties.
