室外门式起重机在电力建设施工中应用十分广泛，其使用过程中会遇到突起大风而制动力矩无法使起重机停止行走的紧急情况。目前门式起重机在遇到突起大风情况一般采取在行走轮下方塞垫方木，待起重机停稳后再上紧夹轨器、拉设防风缆绳等措施。Outdoor gantry cranes are widely used in electric power construction. During their use, they will encounter emergencies such as sudden strong winds and the braking torque cannot stop the crane. At present, gantry cranes generally adopt measures such as stuffing square logs under the traveling wheels when encountering protruding winds, and tightening the rail clamps and pulling wind-proof cables after the crane has stopped.
现有门式起重机突起大风处置方式需靠人工在高速运行的行走轮下方塞垫方木，本身存在一定危险性，且地面指挥人员距离行走轮有一定距离，若反应不及时或人员不足不能同时对同侧2个行走轮采取措施时，易造成起重机出轨倾覆事故。Existing gantry crane handling methods for protruding high winds require manual padding of square wood under the high-speed running wheels, which is inherently dangerous, and the ground commander is at a certain distance from the running wheels. If the response is not timely or there are insufficient personnel, they cannot be used at the same time. When measures are taken on the two traveling wheels on the same side, it is easy to cause the crane to derail and overturn.
