1996年3月17日,某型钢厂南线精轧机的大罩发生故障。为维持生产,该厂决定用行车起吊的方法升降大罩。为确保起吊作业安全,设备厂长组织起重工商讨起吊方案,决定采用两根5m长的钢丝绳捆束大罩两头,再穿一根3m长钢丝绳作“人字”型挂钩,并在大罩基架两侧板上开孔,大罩吊起时插入保护销,防止大罩意外坠落。 用行车起吊大罩连续作业4个班次后,在第5个班,因成品不合格,当班调整工卢某用行车起吊大罩时少用一根3m的钢丝绳,只用2根5m长的钢丝绳,采用“八字”型方法挂钩,钢丝绳2次滑出均未挂上,第3次在另一个调整工的帮助下强行挂钩,大罩吊起时两侧的安全销只插了一个。卢某进入罩内

In order to ensure the safety of lifting work, the director of equipment organized the lifting workers to discuss the lifting plan and decided to use two 5m long steel wire rope to bundle the two ends of the shield and then to wear a 3m long steel wire rope as a “herringbone” Shelf holes on both sides of the board, the cover raised when the protection pin inserted to prevent the accidental fall hood. Lifting the cover with a car after a continuous operation four shifts in the first five classes, due to unqualified products, on-duty adjustment workers Lu used when driving a large cover less with a 3m rope, only 2 5m long rope , The use of “character” type of hook, wire rope 2 times were not linked to slide out, the third time in another adjustment with the help of forced hooks, hoists when lifting the safety pins on both sides of the only one inserted.
