This lift bridge is located over the Kaiser Wilhelm channel, near Brunsb\u00fcttel port. It has a total length of 260 meters and its mainly made of concrete. The bridge has 2 pairs of steel structure towers through which the lift span can move upward and downwards, allowing a clearance for vessels to cross. A picture of the bridge can be seen below:<\/p>\n

Geometry and materials<\/span><\/p>\n

The subsystem chosen for the life cycle analysis is the lift span, located in the center of the total length. This span has 33 meters long and 12.1 meters wide.<\/p>\n

The structural design of the deck consists of an open deck grating with longitudinal box steel girders and transversal beams with section W610x217. A cross-section of the lift span can be seen in the picture below:<\/p>\n

Maintenance interventions<\/span><\/p>\n

The lifetime of the system is defined as 70 years. \u00a0During that period, regular maintenance actions must be carried out over the subsystem. These actions are:<\/p>\n

1. Regular maintenance
\nIntervals: every 3 years
\nDuration: 2 days<\/p>\n

2. Deck replacement
\nIntervals: every 20 years
\nDuration: 14 days<\/p>\n

3. Re-painting
\nIntervals: every 3 years
\nDuration: 2 days<\/p>\n

The timeline below shows the interventions along the system lifetime:
