Shield hoisting new weapon Zhonglian Heavy Industry ZCC3800S crawler crane Nantong construction praised

A few days ago, Zoomlion ZCC3800S crawler cranes appeared in Nantong City, helping the subway shield machine to go down. During the operation, the ZCC3800S crawler crane realized the loading and unloading, turning over and downhole of the shield machine with its 24m main arm and professional shield arm working conditions. Accurate, stable and reliable lifting performance effectively guarantees the smooth completion of the project. The efficient and stable operation creates good economic benefits for customers and wins the unanimous praise of customers.

It is understood that the first phase of Nantong Metro Line 1 has a total length of 39.182 kilometers, with 28 stations and an average station spacing of 1.429 kilometers. The entire line is underground and underground. The target speed of the subway operation is 80,000 per hour. Meter. This line is a backbone line connecting the north and south directions. The large scale of the project, the investment, and the complicated construction management and operation indicate that Nantong has ushered in the subway era since then.

The hoisting shield machine was used for the construction of Pingchao Station to Nantong West Station of the first phase of Nantong Metro Line 1. The construction site is narrow, just enough for the next crawler crane to traverse the track. After the compact ZCC3800S crawler crane is in place, the 24m main boom is used, and the professional shield working condition is quickly installed. The main and auxiliary hooks work together, and the shield machine is loaded and unloaded, turned over, and the lower well is completed in a continuous manner. The whole process is very smooth and smooth.

It is understood that in the past, the hoisting of the shield machine must be carried out by two cranes to complete the flipping. It is not only difficult to locate, but also has a large area, and there are also problems such as coordinated interaction and high operational risk. Zoomlion crawler cranes have overcome technical problems and realized that a single crane allows the shield machine to turn over, hoist, and go down once, so that the shield hoisting can be carried out from two machines to a separate machine to complete the shield flip installation. The huge transformation not only fundamentally guarantees the safety of lifting operations, but also greatly reduces operating costs, improves lifting efficiency and reduces construction area.

The person in charge of the on-site construction said: "The ZCC3800S crawler crane is well-matched in the whole lifting process. The professional shield working condition is easy to install, the double hook lifting weight is displayed in real time, the main and auxiliary hook lifting weight can be automatically distributed, and the operation safety is guaranteed. It is a shield hoisting weapon. In addition, the service of Zoomlion's field technicians is also very thoughtful."

According to Liu Zhigang, product manager of Zoomlion Crawler Crane, ZCC3800S crawler cranes are fully equipped for installation, not only for shield hoisting, but also widely used in wind turbine assembly and disassembly, plant construction, equipment assembly and disassembly, shipyard hoisting and other projects. The price is very high. Since its launch in May 2018, the product has received extensive industry attention, and its excellent product performance and unique technical advantages have been highly praised by customers, and it has become a popular product of Zoomlion.

"ZCC3800S crawler cranes will be favored by more and more customers, participate in more projects and help build beautiful China. Add more aurora green to the major key projects in the country and draw a beautiful landscape." Liu Zhigang said. (This article is from Zoomlion)
