It is primarily employed for transporting and installing secondary lining materials for tunnels, such as steel mesh and shotcrete anchors. Specifically, a secondary lining trolley typically consists of several components, including a frame, a hydraulic system, a moving mechanism, a supporting structure, and a fixing device.
When performing operations inside a tunnel, the secondary lining trolley needs to travel along rails and must maintain its levelness and stability. Typically, the secondary lining trolley is driven by a hydraulic system or an electric motor, enabling remote control and adjustment over long distances.
The main features of the secondary lining trolley include the following aspects:
1. Load-bearing capacity: The secondary lining trolley is designed with a large load-bearing capacity, typically able to support weights ranging from 5 to 10 tons.
2. Mobility and Flexibility: The secondary lining trolley can move freely within the tunnel and can be operated at various angles and positions.
3. Stability: The design of the secondary lining trolley must take into account stability during operations within the tunnel, ensuring safety and minimizing losses.
4. Ease of Operation: The secondary lining trolley should be easy to operate and equipped with remote control functionality, enabling operations without requiring personnel to enter the tunnel.
In summary, the secondary lining trolley is a specialized construction equipment used for transporting and installing tunnel secondary lining materials. When operating inside tunnels, it features high stability and strong load-bearing capacity.
