Bridge Construction Machine 100-200Tons

Bridge Girder Launching Crane, One of the bridge construction machinery, its boom is a box girder, which is hung forward, and there is a collapsible column at the front end. The Beam Launcher can drive itself into the bridge position under no load condition, then straighten the front column and support it on the front pier. When the beam (or the whole beam) moves along the boom, the boom is close to the simply supported beam. When the bridge is bridged, the machine can move into the bridge position on its own in the empty state. First, the beam must be transferred from a special gantry crane to a special beam truck, then the rear end of the girder car and the bridge erecting machine is countered, and the beam is hoisted with two hanging beams on the crane arm of the bridge erecting machine, along the crane arm, to the bridge position. Beam. The main structure of the bridge erecting machine consists of the main beam, the upper cross beam and the front frame, the hoisting crane, the supporting and transecting wheel group, the track system, the supporting wheel mechanism, the front hydraulic top lifting mechanism, the rear driving device, the transport beam flat car, the electrical system and so on.
