New Railway Pamban vertical lift bridge will replace the more than 100 years old strongly deteriorated Scherzer Rolling Bascule Bridge, connecting Pamban Island with the mainland of Tamil Nadu State, in India, promoted by RVNL, Rail Vikas Nigam Limited. The 77.5m lifting span weighs around 650 tons and can be raised 17m in approximately 3.5 minutes. Mechanisms will be located at the top of the two towers, with a 250kW motor per side. Gear box set will reduce the motor 750rpm to 0.5rpm rotation speed of the 3m diameter sheaves, with the operation controlled by variable speed drives. Electrical supply is ensured by an 800 kVA compact substation and two 625kVA diesel generators as backup system. Lighting protection and an adequate earthing system is provided. |
