Description
Product Name: High Braking Performance Synthetic Brake Shoe for Mining Trains Type: Train Brake Certification: ISO14001, ISO9001, Crcc Customized: Customized Frictional Material: Polymer Steel Plate Material: Q235A Brake Shoe Thickness: 45~50mm Brake Shoe Width: 50~85mm Steel Back Plate Length: 300~400mm Surface Treatment: Painting Process: Hot Pressing Speed Application: 90~120km/H Trademark: QL Transport Package: W/CS Specification: Subject to design drawing Origin: China HS Code: 8607210000 Product Description 1. Features:a.The adjustablerange of friction coefficient , it is applicable to various running speeds.b.Thecomposite brake shoe provideshigh abrasion resistance and long service life, so as to greatly reduce the workload of brake shoe replacement and save the costs of maintenance and operation.c. Without sparks when braking, it can avoid the iron powders generated during wear-and-tear andrelieve the impacts on electric equipment.d. It is of light weight, so it can be replaced conveniently and easily.e.It causessmall abrasion and no thermal crack on the tread.f. Thelower friction coefficient at high speed maintains sufficient braking force, improves the braking performance and shortens the braking distance.g. The friction coefficient index can be fully increased. The composite brake shoe is combined with the small-diameter braking cylinder to save compressed air. When braking on long heavy down grade, it may shorten the air recharge time, so as to improve the wagon safety when running on heavy down grade.h.The composite brake shoe won't result in rough tread, so it could reduce the noise level by 8~10dB.i. Compliance with Standard TB/T2403.2. Application: Applicable for freight rolling stock speed at 120km/h, and axle load below 25t.3.
