Safe wind resistance of bridge girder launcher is also an important daily job, professionals to monitor and check is necessary. Operator must learn the structure of bridge bridge girder launchergirder launcher and wind resistance operation tips, strictly follow operation regulations, then the job can be done well. Wind resistance can be divided into daily wind resistance and typhoon resistance, see the table below:

Different measures for different wind resistance types, check the following to find details

In the daily working condition (such as the complete machine crosses piers, moves laterally and installs girder segment), because the bridge girder launcher is fixed with piers or pier top block by support legs, an the same time working anchors are set up for support legs, the bridge girder launcher can still install girder segments and construct with suspended girders with the wind speed < 22m/s; the complete machine can still cross piers and moves laterally with wind speed <16m/s, for special working condition, the machine must work in the limit condition for safety. Electromagnetic hydraulic iron wedge is set up inside of trolley wheels of the bridge girder launcher, when emergency brake is needed because of gust, immediately stop lifting work (or dropping the heavy objects) and moving, cut off power supply for wind resistance iron wedge and stop all operations for the machine. As going off work, move the bridge girder launcher to the crane ground anchor point, trolley stops at the fixed ground anchor point, lock them with corresponding anchors.

When the wind speed > 22m/s, the bridge girder launcher should stop working, check whether general anchoring system is in place, move the lifting trolley to the corresponding anchoring points at the front and rear support legs, anchor lifting trolley, other special wind resistance measures for the bridge girder launcher are not necessary.
