Zoomlion 4.0 crawler crane: Changchun subway project shield downhole is accurate and stable!

Recently, Zoomlion’s ZCC2600 crawler crane successfully helped the construction of the shield machine at the first phase of the Changchun Metro Line 2 in Jilin. The product was consistently praised by customers for its superior and stable lifting reliability.

Meet the challenge of strength

Changchun Metro Line 2 runs through the east-west direction of the city and passes through the Green Park, Chaoyang District, Nanguan District, Erdao District, and the Economic Development Zone. The line passes through Changchun West Railway Station, Culture Square, Yatai Garden residential area, Changchun Economic and Technological Development Zone, and other large-distribution points. It is a large-capacity backbone line in the Changchun line network, with a total length of 36 kilometers. The Zoomlion ZCC2600 crawler crane boosted the first phase of the Changchun Metro Line 2 for 20.5 kilometers. There are a total of 19 stations, all of which are underground stations. The entire line has now started, including the construction of Changchun West Station and Children's Park Station. carry out. Most of the projects use open-cut method and the shield machine is used for construction in the interval. The stability, micro-motion and hoisting accuracy requirements for lifting equipment are very strict and the construction difficulty is relatively large.

Zoomlion ZCC2600 Crawler Crane Construction on Changchun Metro Line 2 Project

Zoomlion’s assistance to the ZCC2600 crawler crane of Changchun Metro Line 2 mainly uses a 23-meter main arm + shield operation condition at the construction site, which is responsible for lifting the shield machine, turning it over and then down the well and installing it in place. Relevant technicians indicated that the technical highlights of the ZCC2600 crawler crane shield work condition are mainly embodied in the compact structure, small footprint, suitable for urban construction with restricted venues, capable of carrying on load, and covering the entire work area.

Zoomlion crawler shield shield working condition is a special construction condition for the shield tunnel construction specially developed for the needs of the national urban rail transit construction. It can safely, efficiently and quickly complete the shield machine loading and unloading, turning over, down the well and other actions, the entire process is not In more than 30 minutes, it has broken the previous construction method in which the downhole of a shield machine requires double-crane joint lifting.

At the same time, the equipment is also suitable for different shield machine lifting, lifting coverage, lifting performance, sufficient lifting capacity; equipped with professional shield arm conditions, easy installation, can achieve the shield machine loading, turning, downhole carry out. In addition, the equipment can not only realize the real-time display of the weight of the double hooks, but also automatically allocate the weights of the main and sub hooks to ensure safe operation; it can also implement one-click conversion of single hooks and double hooks, and the construction conditions can be converted efficiently and quickly; Function, suitable for the accurate butt joint of the shield shield.

Intelligence and performance improve "Zhonglian 4.0" feels extraordinary

The ZCC2600 crawler crane is Zoomlion's first crawler crane 4.0 product. Its mechanism operating speed is increased by 20%, light-load high-efficiency compounding is not decelerated, and the whole assembly time is less than or equal to 6 hours; the safety monitoring system is full-time real-time detection and monitoring. , To ensure the safety of the work; the largest single piece of transport weight is 30.5 tons, the transport width of 3 meters, is the only domestic crawler crane products that meet the new road requirements.

The equipment's main boom is suspended and installed at a length of up to 47 meters. It is easy to maintain and maintain; the pull plate can be transported with the arm section, and the disconnection position is optimized and the installation is more convenient. The icing on the cake is that the ZCC2600 is also equipped with a full-field operation room, with centralized operation of buttons and switches, making it easy for all types of personnel to operate; an all-around air-conditioning outlet to ensure a comfortable operating space; on the APP side of mobile phones, cranes can be realized. Equipment management, statistical reports, maintenance, fault alarms, equipment positioning and trajectory playback, improve equipment management and business operation efficiency.

Construction Site

According to feedback from the project site construction supervisor, the ZCC2600 crawler crane has been closely coupled in the entire hoisting process of the project, prompting the project to proceed smoothly. The construction party of the project applauded the quality, performance and construction hoisting conditions of Zoomlion crane products, and was very satisfied with the service attitude of the on-site technicians.
