Product specification

Product advantages

Compared with rubber gangway, pucker vestibule gangway has below advantages:

· Air tightness improved, the leakage time when the air pressure in the gangway drops from 3600Pa to 1350Pb is not less than 50s.

· Sound insulation performance improved, sound reduction index RW≥25dB

Below is there different types of Interconnecting Gangway FYI

S.No.	Type	Features	Picture
1	EMU High-speed Train Gangway	Small passage width
		No interior panel (roof panel & side panel), simple structure
		High requirements to sound insulation, thermal insulation, air tightness
		Meet the aerodynamic load requirement for trains meeting with high speed
2	Metro Gangway	Big passage width
		Most of projects have interior panel
		Sound insulation 27~40dB, no air tightness requirement;
		Meet the requirements of quick connection and disconnection
3	Tram Gangway	Big passage width, outer profile is almost same size as car body
		Usually without interior panel
		Sound insulation 12~25dB, no air tightness requirement
		Puckered type, meet small curve passing requirement
