我厂750公斤汽锤是一台老设备,它的防止撞缸保险装置是保险刀。当锤头提升到极限高度时,碰到保险刃,使锤头下落。操作过程中,常常发生锤头碰保险刀之后急速速落下的情况,造成工伤事故,打伤汽锤司机的手臂。这种保险装置只能保险设备,而对工人却是很险危的。去年又发生了一起因锤头急速落下造成工人手指骨折的严重工伤事故。我车间钳工小组的同志看在眼里,痛在心上。在新生的革命领 I plant 750 kg hammer is an old equipment, its cylinder collision avoidance insurance device is a knife. When the hammer raised to the limit height, hit the insurance blade, the hammer fell. During the operation, it often happens that a sharp impact occurs after the hammer touches the safety knife, causing a work injury accident and injuring the hammer driver’s arm. This kind of safety device can only insure the equipment, but it is very dangerous to the worker. Last year, there was another serious work-related injury that caused fractures of the fingers of workers due to the rapid fall of the hammer.
