Railway Tubular Rubber Diaphragm Exported To Korean meet with UIC845
Product review
A gangway connection (or, more loosely, a corridor connection) is a flexible connector fitted to the end of a railway coach, protecting from windy and raining and enabling passengers to move from one coach to another without danger of falling from the train. It can be divided to following types:
Iron vestibule diaphragm
Rubber vestibule diaphragm
Pucker vestibule diaphragm
With capacity of supply 30000 sets in past 11 years to CRRC, we has been manufacturing tubular diaphragms using elastomers that meet and exceed fire and smoke toxicity standards.
We can used digital simulation to analyze the configuration of railway cars, especially radius of turning circle to ensure diaphragms have the right dimensions and perform optimally.
