The Design And Construction Of The Prai Swing Bridge For The Electrified Double Track Project Between Ipoh And Padang Besar
The new Prai River Swing Bridge is located along the new 328km electrified double track from Padang Besar to Ipoh in Malaysia, currently under construction by MMC-Gamuda JV. It provides rail access between the Butterworth and Prai sections of the Penang Port. It is 13m wide and swings open approximately 72° to provide two(2) navigational channels with a minimum clear width of 30m each.
Since the Prai Swing Bridge is also part of the Electrified Double Track Project, provisions have been made for the installation of the Overhead Catenary Structure (OCS) at approximately 15m intervals along the bridge. The new Prai Swing Bridge carries two(2) rail tracks with galvanised steel sleepers spaced at 500mm. The UIC54 running rails, canted to 1:20, are fastened to the sleepers using Pandrol e-clips with cast iron bearing plates. Resilient pads made of natural rubber are used as rail-seat on the bearing plate. In each of the track, guard rails are also installed.
The electro-hydraulic drive consisting of the center pivot, one(1) lifting cylinder, four(4) turning cylinders, four (4) bridge locking cylinders and four(4) rail locking cylinders serve to slew and lock the new Prai Swing Bridge together with the rail locks. Activation of these cylinders is controlled by two(2) numbers of Industrial PC Simatic IPC547D located at the Control Building and a Simatic Multi-Panel MP277 at Pier 5. The Center Pier and the Control Building is linked by a set of submerged cables which carries the power supply for the equipment as well as the control signal and communication.
This project was awarded the IEM 2013 Award for the Outstanding Engineering Achievement.
