为确保天车的安全生产,平时就应定期进行安全检查,在有地震预报的地区,则更要及时进行防震安全检查。 在地震过程中,天车和其它机械设备一样,要承受地震力的作用,通常只考虑水平地震力的影响,水平地震力可由下式计算: Q=cka.W 式中c──结构影响系数, k──裂度影响系数, a── In order to ensure the safety of Crane, safety inspection should be carried out on a regular basis. In areas with earthquake prediction, earthquake-proof safety inspection should be carried out in time. In the course of an earthquake, the crane, like other mechanical equipment, is subject to seismic forces and usually only considers the effects of horizontal seismic forces. The horizontal seismic force can be calculated as follows: Q = cka.W where c - structural influence coefficient , k──Leave coefficient of influence, a──
