What’s the difference between a secondary lining trolley and a tunnel trolley?
Both secondary lining trolleys and tunnel trolleys are specialized equipment used for material transportation in confined spaces such as subway tunnels and tunnels. The differences between them lie in the following aspects:
1. Vehicle Structure: A secondary lining trolley typically consists of components such as a platform, running gear, support system, suspension system, and propulsion system. In contrast, a tunnel trolley includes components such as a running section, cargo-carrying section, suspension system, and steering system.
2. Applications: Secondary lining trolleys are typically used for secondary lining operations and concrete pouring in underground construction projects. Tunnel trolleys, on the other hand, are primarily used for material transportation in confined spaces such as tunnels and subway systems.
3. Different functions: The secondary lining trolley features multiple functions, including smooth operation, precise positioning, and suspended rotation, enabling it to perform various operations such as positioning, lifting, and suspended rotation of concrete segments. In contrast, tunnel trolleys are primarily used for material transportation in underground stations, tunnels, and other similar environments.
4. Payload Capacity: The payload capacity of a secondary lining trolley is typically smaller than that of a tunnel trolley, usually ranging from 10 to 20 tons. In contrast, tunnel trolleys can be designed with varying load-bearing capacities and dimensions according to specific requirements, with a typical payload capacity exceeding 20 tons.
5. Drive Systems: The drive systems for secondary lining trolleys and tunnel trolleys also differ. Secondary lining trolleys typically use electric drives, whereas tunnel trolleys commonly employ various drive systems such as diesel engines or rechargeable batteries.
In summary, the secondary lining trolley and the tunnel trolley differ in terms of vehicle structure, application scenarios, functionality, payload capacity, and drive mechanism. Therefore, when selecting appropriate transportation equipment, it is essential to make choices based on specific needs to meet the requirements of construction projects or production processes.
