What is a low tower crane?
Low-Clearance Tower Crane is a specially designed tower crane mainly used in construction scenarios with limited space or strict height restrictions. Compared with traditional high tower cranes, it is characterized by a lower tower height but greater flexibility and adaptability, making it suitable for dense urban areas, indoor construction or low-rise building projects.
1. Core features of low tower cranes

1.height limit: Usually the height of the tower does not exceed 20 meters, which is suitable for low-altitude operations.
2.Compact design3.Quick installation: Modular structure facilitates assembly and disassembly.
4.load capacity: Although the height is low, the load range is similar to that of conventional tower cranes (1-10 tons).
2. Application scenarios of low tower cranes
| scene type | Specific applications | Advantages |
|---|---|---|
| urban renewal | Renovation and underground engineering of old residential areas | Avoid high-altitude obstacles such as high-voltage lines |
| indoor construction | Factory construction, large venues | Accommodates roof height restrictions |
| transportation hub | Subway station and bridge maintenance | Avoid affecting surrounding traffic |
3. Comparison between low tower crane and traditional tower crane
| Comparative item | Low tower crane | Traditional tower crane |
|---|---|---|
| Applicable height | ≤20 meters | 50-300 meters |
| Installation time | 1-2 days | 3-7 days |
| Venue requirements | Minimum 5m×5m | Minimum 10m×10m |
| Typical load | 5 tons (arm length 30m) | 10 tons (arm length 50m) |
4. Correlation analysis of hot topics on the entire network in the past 10 days
Recently, low-level tower cranes have attracted attention due to the following hot events:
| Date | hot events | Relevance |
