Last week, the first shield machine “Rongyao No. 1” of the Fuzhou Metro Binhai Express Line 1, contract 3 construction area including 1 station and 1 section, constructed by the Eighth Bureau of China Railway, was successfully hoisted down the shaft. Zoomlion’s ZCC3500V crawler crane was used as the main crane for this hoisting.

It is reported that the shield machine has a diameter of 8.6 meters and a weight of 135 tonnes. After being assembled on the ground, the shield machine is hoisted and lowered into the well. The middle and front shield is integrated, divided into four blocks (bottom block, left block, right block and bottom block) to be hoisted down into the well.

The middle shield weighs 110 tonnes and is divided into four parts, plus H beams, and assembled on the ground for hoisting down the well. At present, the hoisting and assembling of large shield machines are basically completed.
