BEAM LAUNCHER WITH THREE AUTO ANCHORAGES AND OIL CYLINDER

Provided is a beam launcher having three automatic anchorages and a hydraulic cylinder. Three automatic anchorages and a hydraulic cylinder are installed in a beam launcher, so bridges can be built in both directions. Three automatic anchorages and the hydraulic cylinder instead of an existing beam launcher anchorage, which is manually operated, are used so that anchoring can be automatically performed. Therefore, the beam launcher can achieve more stability than the existing anchorages. When a bridge, which is equal to or higher than 40 meters, is dismantled, or when a maritime access bridge, a river crossing section, and a gantry bridge for passing through an existing bridge are dismantled, the beam launcher can be easily applied.
