The Jingkou Jialing River Grand Bridge is an important component of China's "Eight Verticals and Eight Horizontals" high-speed railway network along the Yangtze River, and is a key project of the Chengdu Chongqing Middle Line high-speed railway. After the completion of the project, it will further compress the spatial and temporal distance between Chongqing and facilitate the travel of residents along the route.

The construction difficulty of the Jingkou Jialing River Extra Large Bridge is extremely high. It not only spans the Jialing River and Jiuqu River Wetland Park, but also 70% of the piers are located near the existing railway, as well as crossing Jinhai Avenue, Second Horizontal Expressway, G212 National Highway, and under construction Metro Line 15. In such a complex environment, the construction team constantly innovates construction methods.

In the fully enclosed hanging basket construction protection plan, the chain hoist plays an important role. When the fully enclosed hanging basket is in operation, key construction points are required. When working inside the point, after the main and rear anchors are released, two 10t chain hoists will be used to evenly pull the hanging basket. Due to the precise control required during the operation of the hanging basket, the hand-operated hoist has the characteristics of simple operation and precise control of traction force, which can ensure the smooth movement of the hanging basket and avoid safety hazards caused by unstable operation on existing lines. During the walking process, it is necessary to switch the position of the track anchoring device. After the hanging basket is in place, the rear main anchor should be fixed. In this series of operations, the stable traction of the chain hoist provides a guarantee for the smooth completion of the hanging basket walking. It can not only meet the demand for traction tools in construction, but also be flexibly applied in limited construction space due to its small size, ease of installation and disassembly, greatly improving construction efficiency and ensuring the safety and stability of construction in complex environments.  

The fully enclosed hanging basket walking chain hoist of Jingkou Jialing River Extra Large Bridge plays an important role in ensuring the safety of equipment work, improving work efficiency, and accelerating project construction progress.
