It is understood that the front shield section is the heaviest component of the shield tunneling machine, with a total weight of 120 tons. This time, the XGC260 adopted a dedicated shield hoisting configuration, operating with double hooks. The main hook was responsible for lifting the main body out, and through coordination with the auxiliary hook, the front shield was flipped. The entire process took only 30 minutes. In the past, this operation required at least two cranes working together for tandem lifting, which was inefficient, costly, and carried high safety risks.

      It is reported that the shield tunneling machine hoisted out of the shaft will be transferred to the left line of the connected interval, where the XCMG XGC260 will still perform the hoisting and lowering task.
