China-Made Composite Brake Shoes for Kazakhstan Rolling Stocks China Brake Shoe China Brake Block

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 causessmalPneumatic Tools l 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. It generates low noise without squeaking.
h.The composite brake shoe won't result in rough tread, so it could reduce the noise level by 8~10dB.2. Application:
Applicable for freight rolling stock speed at 90km/h, and axle load below 21t.3.
