At this time, loosen the connection screw of standard section with spanner, hang the shaft of hand crane on the upper angle bar, sway the shaft of hand crane upward, separate this standard section from the next section, and lay it in the suspension coop, dismantle the other standard section for the same method, and turn the shaft to another direction, draw the lifting wire rope tightly, the operation staff leave the suspension coop, open the lock stopping instrument, fall the suspension coop to next position and lock the brake instrument, the operation staff return to the top of suspension coop, continually dismantle note: forbid the staff leave on the top of suspension coop or in the coop when the suspension coop is running

8.1折除时，首先将吊笼用停层装置停靠在待拆除的标准节的下两节上，操作人员上到吊笼顶，卷扬机松绳，用小吊杆将顶梁略向上提起，拔出顶梁横销，使顶梁值得徐徐降下，降到拆除节下一节中间框架角处，并重新穿上横销，这时用板手将标准节连接螺栓松开，将手摇起重机小吊杆钩挂在待拆节上框架用钢土，到吊笼内，用同样的方法拆下另一节标准节，然后将吊杆转向不影响升降机运行的方向，收紧起升钢丝绳，操作人员离开吊笼，打开锁止机构，使吊笼下降到下一个拆除位置，并将锁止机构锁死，人员重返笼顶，进行下一拆除循环注意：在吊笼运行时绝不允许有人员留在吊笼顶部或吊笼内

When dismantle the machine, firstly, stop the suspension coop on the lower 2 sections of the standard sections, the operation staff go on the suspension coop top, the hoisting machine loosen rope, lift the pillar with small shaft, pull out the horizontal pin of pillar, let the pillar fall slowly to thedismantled section's middle angle bar, insert the horizontal pin again. At this time, loosen the connection screw of standard section with spanner, hang the shaft of hand crane on the upper angle bar, sway the shaft of hand crane upward, separate this standard section from the next section, and lay itin the suspension coop, dismantle the other standard section for the same method, and turn the shaft to another direction, draw the lifting wire rope tightly, the operation staff leave the suspension coop, open the lock stopping instrument, fall the suspension coop to next position and lock the brakeinstrument, the operation staff return to the top of suspension coop, continually dismantle note: forbid the staff leave on the top of suspension coop or in the coop when the suspension coop is running
