Subway construction often faces the challenges of narrow tunnels and limited working space, and the transportation and hoisting of equipment components are key links that affect the construction progress. In such complex scenarios, the hand-operated hoist, with its advantages of small size, light weight, and precise lifting, has become a "secret weapon" to accelerate equipment installation and inject efficient power into subway construction.
The internal pipelines of subway tunnels are dense and the passage space is limited, making it difficult for large lifting equipment to enter and operate. Hand cranked hoists do not require complex power sources and can be operated manually, allowing them to flexibly shuttle through narrow areas. Whether it is precision components such as small motors and valves, or heavier steel structure accessories, it can be lifted smoothly and positioned accurately, avoiding the risk of collision with surrounding pipelines and structures during large-scale equipment operations and ensuring construction safety.
Compared to traditional lifting methods, hand cranked hoists are easy to operate, quick to disassemble, and do not require professional technicians to be on duty throughout the entire process, greatly reducing labor costs and operational complexity. At critical nodes of equipment installation, construction personnel can quickly deploy hand cranked hoists to achieve multi-dimensional operations such as vertical lifting and horizontal dragging of components, effectively shortening the lifting cycle and buying valuable time for subsequent installation processes.
In the high-intensity and demanding working environment of subway construction, the hand-operated hoist has solved the problem of lifting in narrow spaces with its strong adaptability, safety and reliability. It not only improves the efficiency of equipment installation, but also strengthens the construction safety defense line, becoming an indispensable small lifting equipment in the smooth progress of subway projects, demonstrating the important value of "small tools" in "large projects".
