The subway is an important element of modern cities. It not only greatly alleviates the traffic pressure of the city, but also promotes urban development and plays a very important role in driving the economy, leading the rapid development of the city's economy. The construction of subway is a major project, which requires high requirements for the use of lifting tools and equipment.

During the construction of the subway, strict requirements were placed on the use of lifting tools due to space limitations. Some large mechanical equipment cannot operate in tunnels, and construction workers can only rely on light and small lifting tools such as Guanhang chain hoists and hand cranked hoists for construction operations. Hand pulled hoists play a crucial role in helping workers lift steel and install machinery during subway construction, greatly improving work efficiency, saving labor, and accelerating subway construction progress.

More and more people are choosing to take the subway for transportation, which is not only convenient and fast, but also environmentally friendly. The subway has become an important means of transportation in cities.
