Can I hang it in rainy days?

Legal analysis: there is no legal provision that is not allowed, but it is not suitable. First, rain and snow weather affect the line of sight. /kloc-the crane boom of 0/0 ton is about 20 meters, and the crane boom of 25 ton is over 30 meters. In other words, the sight distance of the crane driver should be kept at about 30 meters when hoisting. However, the rain and snow weather shortens the driver's sight distance, especially the snowfall, which may be less than 10 meter, which is very likely to cause the hook to collide with other objects. Second, the rain and snow weather affects the friction coefficient. Rain and snow will make hooks, ground wet, wire ropes, etc. Wet. When these spreaders get wet, the friction coefficient will decrease. For example, the ground may slip and the hooks may get wet, which is also the risk of lifting the seat belt. Third, the rain and snow weather affects the safety of equipment. Some numerical control equipment and precision equipment will be damaged by rain. Although some rainproof measures can be taken, such as covering awnings and ponchos, it is inevitable that accidents will occur when water enters. Based on the above considerations, the equipment hoisting operation should not be carried out in rainy and snowy weather, and the ongoing hoisting operation should be stopped immediately in rainy and snowy weather.
