Full span method means to install one whole span precast girder at one time. Generally the full span method is suitable for bridge with span 20-50m and girder weight 30t-900t.The straddle carrier is carrying a full span.
The pre-cast bridge span is lifted from the formwork by means of either a gantry or a special straddle carrier.The pre-cast span can also be moved out of the formwork by using special trolleys placed at the bottom of the formwork.Lifting gantry crane is hoisting the bridge span to viaduct bridge top.
The Trolley transports the bridge span over the previous erected span to our full span launching gantry,which is positioned at the span to be erected next. Bridge span transporter transport the bridge span to launching gantry crane for span-feeding.
