锡矿山矿务局在洛阳矿山研究所、洛阳矿山机器厂、江西电机厂紧密配合下,运用国内外先进技术,改造老式的KJ2×3×1.5D卷扬机取得成功。该局南矿二直井KJ2×3×1.5D型卷扬机系我国六十年代初仿苏四十年代产品制造的。这种设备安全装置很不完善,曾于1979年发生过制动器卡缸和拉杆拉断,而造成飞车跑罐重大设备事故。同时还存在着绳鼓钢绳缠绕紊乱问题,每年要多耗钢绳650
With the close cooperation of Luoyang Institute of Mines, Luoyang Mining Machinery Factory and Jiangxi Electric Machinery Factory, the Xikuang Mining Bureau successfully upgraded the old KJ2 × 3 × 1.5D winch with advanced technology at home and abroad. Bureau of the South Mine two wells KJ2 × 3 × 1.5D-type winch in China in the early 1960s imitation Su-40’s manufacturing. This equipment safety device is very imperfect, had occurred in 1979 brake card cylinder and pull rod pulled off, resulting in speeding tank runaway major equipment accident. At the same time, there is a rope drum rope winding disorders, each year to consume more steel 650
