-
GJ-I fastener for vibration and noise reduction
It makes full use of the rubber features: big shearing deformation and dynamic elasticity, to isolate the transfer of vibration between wheel and track. -
GJ-II single-baseplate fastener
The fastener is a kind of common fastener and can be applied to normal sections of rail tracks without special requirement for vibration and noise reduction. -
GJ-III Two-layer Fastener for vibration and noise reduction
Laying length is over 300 km in 7 years. -
Suggestion for urban rail transit
0 dB~3 dB GJ-II. 5 dB~8 dB GJ-V or GJ-I. 8 dB~10 dB GJ-III or GJ-III2. 10 dB~12 dB GJ-IV. 12 dB~15 dB Anti-vibration slab mat. 15 dB~20 dB Combi of GJ-IV and mat. -
GJ-III2 Two-layer Fastener for vibration and noise reduction
GJ-III2 is GJ-III fastener upgrade products. -
GJ-IV floating rail fastener
It is a new-type fastener with high performance in vibration reduction, the insertion loss can reach up to more than 12dB. -
GJ-V Fastener
Using compression elastic material provides suitable support stiffness. It can substitute for Cologne egg (GJ-I). -
Anti-vibration slab mat
It is mainly used under ballast track bed or slab as elastic support and shows good Vibration isolation performance. -
