dropped load 是什么? in the nuclear power stations during normal station operation and maintenance procedures, there is a demand to move heavy loads using cranes and lifting beams. during load handling, there is a potential for the load being carried to be dropped. dropped objects generally have relatively high velocities which can cause a great damage to the impacted structure. however, this damage is normally very local and includes yielding of materials, local buckling and, in some cases, local failure or penetration. an incident of this nature might directly or indirectly cause a fault which could lead to an increased risk of a radiological hazard. therefore, it is very significant to perform such structural integrity assessment of dropped load. a periodic safety review is needed to make sure that all the lifting equipments work properly under the norms of health and safety. 起重机、行车吊物高空落下叫dropped load. doomed plane dropped load to stay in the air: tsb飞机失事也叫dropped load查看更多
