Design of an electrified double-track railway swing bridge in Malaysia
|Issue:||"Steel Construction", March 2011, n. 1 v. 4|
A new swing bridge for an electrified double-track railway has been proposed in Malaysia to replace an existing 40-year-old single-track swing bridge. The proposed swing bridge has two equal cantilevers each 45 m long and features a steel ”sail” on both sides as the main longitudinal structural element. The 9.1 m wide bridge deck is a composite design — steel structure with concrete slab. The swing span will be powered by means of an electrohydraulic drive situated in the centre pier and slews over the centre bearing located below the centre pivot shaft.
