2010年,智利发生罕见矿难,33名矿工被困井下长达2个月之久,其救援过程牵动全球人心。就在这起矿难中,美国雪姆公司生产的液压钻机配备有伊顿可承受更高工作压力的CMX负载敏感多路阀,连续工作长达30天,不断打碎岩石,钻出逃生通道,成功解救了全部受困工人,创造了“奇迹”。 In 2010, a rare mine disaster occurred in Chile, and 33 miners were trapped underground for as long as two months. The rescue process has affected global public concern. At this mine disaster, the hydraulic drills manufactured by the U.S. company Shermer were equipped with Eaton’s CMX load-sensing multi-way valve capable of withstanding higher work pressures, continuously working for up to 30 days, breaking rocks and drilling escape routes successfully. Rescued all the trapped workers, creating a “miracle ”.
