What is the difference between a single-girder bridge crane and a double-girder bridge crane? Which one should I choose?

Choose a single beam: For light loads (≤20 tons), small spans (≤22 meters), low frequency, limited budgets, and compact spaces (such as small warehouses and assembly workshops).

Choose a double beam: For heavy loads (>20 tons), large spans (>22 meters), high frequency, requiring high precision/multi-functionality (such as double hooks and attachments), and long-term, high-intensity operations (such as heavy-duty factories, metallurgy, and ports).

If your workload is critical (e.g., 20 tons and a span of 22 meters), consider a double beam. While the initial cost is higher, the long-term safety and durability are more guaranteed, making it particularly suitable for high-frequency applications.
