北京矿务局城子煤矿与抚顺煤炭研究所协作,研制成 S—76型斜井两用罐笼。它既可用于运送人员,又可用于提货。在运输作业中不需摘挂钩,从而简化了井口、井底操作工序,使辅助时间缩短,又保证了安全。于1979年6月,S—76型斜井两用罐笼样机,在现场做了工业性试验,以不同的终端载荷(达8430公斤)和不同速度(达3.3米/秒)下放,进行了11次人为脱钩和不脱钩的试验得 Beijing Mining Bureau Chengzi Coal Mine and Fushun Coal Research Institute, developed into S-76 inclined shaft dual-purpose cage. It can be used both for transporting people and for picking up goods. In the transport operations do not need to pick the hook, thus simplifying the wellhead, bottom of the operation process, so that auxiliary time is shortened, but also ensure the safety. In June 1979, the S-76 dual-purpose inclined cage prototype was tested in the field with different end loads (up to 8430 kg) and different speeds (up to 3.3 m / s) for 11 The second person decouples and does not decouple the test
