The subway tunnel at night is brightly lit. Mr. Wang, the operator of the lifting trolley, is staring intently at the control panel in front of him. Every action he makes is related to the safe lifting of dozens of tons of materials.

The lifting trolley is the "strongman" of subway construction, but its operation requires extreme precision. Master Wang gently pushed the control lever, and the steel wire rope slowly tightened, causing the prefabricated pipe segment weighing 15 tons to rise steadily. His eyes were fixed on every movement trajectory of the pipe, and his ears listened to every sound of the pulley running.

Mr. Wang has been working in this small operating room for eight years. He is familiar with every component of the lifting tackle and can judge the operating status of the equipment through subtle vibrations. Every time he lifts, he must accurately calculate the weight of the material, the lifting angle, and the path of movement to ensure that nothing goes wrong.

The subway construction environment is complex, the underground space is limited, and the surrounding pipelines are dense. Master Wang's operation must be precise to centimeters, ensuring both construction progress and safety. He often says, "The lifting tackle is not a machine, it's my partner

As the last batch of materials safely landed, Mr. Wang wiped the sweat off his forehead. He knew that it was these seemingly ordinary daily tasks that slowly built the underground arteries of the city. In this unknown underground world, he and his lifting tackle silently guard every step of the subway construction.
