In the main cable installation project of the Shuangliu Yangtze River Bridge in Wuhan, the lifting pulley played a crucial role. As the "lifeline" of the bridge, the main cable bears the responsibility of pulling the bridge deck, forming support, and distributing the weight of the entire bridge to the main tower and anchorage. Its installation work cannot be neglected.

During the construction process, the construction team selected suitable lifting tackle. These lifting tackle structures are exquisite, consisting of main components such as wooden frames, pulleys, short shafts, and ropes. The quality of the core component pulley directly affects its performance. From a type perspective, single door, double door, and multi door pulleys are used in different construction scenarios, and their connection methods with suspended objects are diverse, including hook type, chain link type, hanging ring type, and hanger type. For small and medium-sized assignments, hook type, chain link type, and hanging ring type pulleys frequently appear; In large-scale homework scenarios, large hanging ring and beam type pulleys show their skills.

In the traction and lifting process of the main cable strand, the lifting pulley shows great power with its own advantages. The construction personnel ingeniously assembled the lifting pulley with equipment such as winches into a complex and efficient pulley system. With the help of these pulley systems, the construction team can accurately change the direction of the traction steel cables, allowing the cable strands weighing several tons to move smoothly at a height of hundreds of meters and gradually complete the installation. Throughout the entire installation process, the lifting trolley withstood rigorous tests, ensuring that each cable strand was accurately and correctly installed in place, making great contributions to the smooth progress of the main cable installation project of the Wuhan Shuangliu Yangtze River Bridge.
