北票台吉矿机运区研制成功多绳摩擦式提升机缶笼正位安全闭锁装置。该装置经过半年运行,效果良好,安全可靠,为我矿竖井提升安全生产创造了良好条件。过去提升机由于没有缶笼正位安全闭锁装置,曾造成将矿车推入井筒的重大事故。使用缶笼正位安全闭锁装置,防止了矿车坠井事故的发生。 Beipiao Taiwan Jianyun Jianyun successfully developed multi-rope friction hoist cage positive safety lock device. After six months of operation, the device has achieved good results and is safe and reliable, which has created favorable conditions for mine mine shaft to enhance safety in production. In the past, the elevator had caused a major accident that pushed the tub into the wellbore due to the absence of the cage safety lock. The use of cage cage is a positive safety locking device to prevent the occurrence of mine car accident downfall.
