zbrf was awarded at the beginning of 2020, after 10 months efforts, we finished the supply of rail fastenings to project of wuyishan tram projects.
the fastening systems are w14-ct and wt-2, which are both developed by zbrf.
this line is 26.17km long, designed speed is up to 70km/h, axle load 13tons, by using track 60r2, welded connection.
consider the requirements of project for comfort, zbrf designed the fastening in low stiffness, it is 45-55kn/mm. the properties of this fastening are as below:
longitudinal resistance is more than 9kn
fatigue properties meet requirements of en13146-4, after 3 millions cycles testing, none components broken, gauge increasing within 6mm, change of clamping force within 20%, change of longitudinal resistance within 20%, static stiffness change within 20%.
electronic resistance : no less than 5kohm
extreme weather condition influence test meets requirements of en13146-6, after 300 h sst, any of components could be removed by hand.
puling out of casting inserts: no less than 70kn
gauge adjustment: -12~ 12mm, in step of 2mm
height adjustment: 10mm, in step of 1mm
