河北省公路工程局设计和制造的公路桥梁装配式架桥机今年首次在怀来县永定河大桥使用。架桥机全长72米,自重217吨,最大架梁能力80吨。三个支腿把整机分为两段。前支腿与中支腿之间为架梁段,长32.5米,中支腿与后支腿之间为平衡段,长39.5米。支腿横梁上面,贯通全长的两个纵梁由公路钢桥桁架装配而成。纵梁上面有两个天梁,可在纵梁上沿纵向自动走行。天梁上有两个起吊构件用的5
The highway bridge assembly type erecting machine designed and manufactured by Hebei Highway Engineering Bureau is used for the first time this year in Huailai County Yongding River Bridge. Bridge machine length of 72 meters, 217 tons of weight, the maximum beam capacity of 80 tons. Three legs of the machine is divided into two sections. Between the front leg and the middle leg for the girder section, length 32.5 meters, the middle leg and the back leg between the balance section, 39.5 meters long. Outrigger beam above, through the full length of the two stringers assembled by the highway steel truss. There are two girders above the stringer, which runs along the stringer longitudinally. Sky beam has two lifting components 5
