Railway Infrastructure Construction
Subway Track Laying Gantry Crane
The subway track laying gantry crane adopts CD1/MD1 type electric hoists, which feature simple structure, stable performance, and strong durability, for coordinated lifting operations. The crane travelling mechanism adopts vertical drive devices for separate drives, and control can be realized through single or multiple linkage control. The gantry crane uses a compact box-type structure, with variable span and height to adapt to tunnel space. During operation, multiple cranes work together in synchronized lifting.
- Easy to install and operate, with low maintenance cost.
- Adjustable running speed and high handling efficiency.
- Compact structure, suitable for operation in confined spaces.
- Strong versatility, suitable for various types of subway tunnels.
- Equipped with automatic span and height adjustment function.
- Can be transported and relocated as a whole.
- This type of gantry crane is specially designed for subway track laying projects. It is mainly used for lifting track panels, formwork, and rebar installation in subway track construction; the worksite is usually in confined spaces such as subway sections.
- Based on the load and frequency of use, the crane is designed with a working class of A3 or above.
- According to the needs of subway construction, the track laying gantry crane is required to have automatic span and height adjustment functions; it meets the working conditions of all types of subway tunnel track engineering projects in China. The crane can pass through platforms, screen doors, small curve sections, and cross-passages, and can be transported and relocated within tunnels without disassembly.
- Relative humidity: 55%–85%; flammable gas concentration not exceeding 10% of the lower explosive limit. Ambient temperature: -25℃~+40℃.
