当一个罐笼停靠在井口,另一个罐笼停靠在井底停车线水平,这种过程是提升机完成了一个完整的提升循环。若是违反了提升程序速度图操作(如提升司机的误操作、控制调节器件的失灵…等),将会出现速度限制器或者是终点限位开关动作,安全制动闸抱闸,使罐笼停留在过卷后的限界内。在这种情况下,提升司机如若为了改变罐笼过卷后的位置而把安全制 When one cage is docked at the wellhead and the other cage is docked at the level of the bottom line, this process completes a complete hoist cycle. If it violates the promotion program speed map operation (such as improving the driver’s misoperation, control the adjustment device failure, etc.), there will be speed limiter or the end limit switch action, safety brake brake, the cage stays in Within limits after the roll. Under such circumstances, if the driver is required to upgrade the safety of the cage after it has been rolled up
