For the main movement of B type curing press is from the traditional vertical raising and down to turning improved into vertical raising/down then flat movable, the reliability of this design is providing with hidden guide rail, it is move safe for the segmented mold and increasing service life to assure the accuracy of cured tire.

Research purposes:The structure or foundation of urban mass transit usually distort,resulting in track distortion and irregularity which serious endanger the traffic safe,so it is very important to monitor the track distortion of urban mass transit for the purposes of keeping accidents away and guaranteeing the safe running of urban mass transit.

This paper analyzes the vibration reduction characteristics of ladder tracks by numerical simulation and experiments based on the vibration experiments performed in the Laboratory of Tunnels and Underground Works of Beijing Jiaotong University.

Study on the Construction Technology of Ladder Sleeper Vibration Reduction Ballastless Bed on the Urban Rail Viaduct

The paper describes the design of plane layout of ladder sleepers on curve sections with super-elevation and the method of installing super-elevation on curve sections.

The transfer mechanism of longitudinal forces of the rail equipped with ladder sleepers on bridge is different from that of traditional ballastless track because of structural differences.
