This animation is for Low Type Segment Erector (SE) or some people called it Segment Lifter. This SE will be use in launching the SBG for 65m and 100m special crossing span. Balance Cantilever method will be use for lauching the SBG. Low type SE mean the SBG only can be lifted from the respective span, NOT from the apposite span. For High type SE, the SBG is be able to launch from either respective and opposite span...Its more flexsible but required higher space. High type SE is NOT suitable for high restricted area (due to HT overhead power cable ect)
