我公司承担的施工项目,大多属于弄堂厂房,工地的垂直运输,很多是采用装摇头扒杆的井架。因为施工场地小,操纵工视野受到限止,当施工高度接近扒杆起升高度时,容易发生“串顶”事故。针对这种情况,我们在原摇头扒杆的上下葫芦之间装了如下图所示的保险装置,效果很好。 Most of the construction projects undertaken by our company belong to the hallway of the Nongtang factory and the construction site, and many of them are equipped with derricks equipped with shaking head masts. Because the construction site is small, the visibility of the operator is limited, and when the construction height is close to the lifting height of the mast, the “string top” accident is likely to occur. In view of this situation, we installed the fuses as shown in the following figure between the upper and lower hoists of the original shaking head mast, which worked well.
