FAQ
1. What is the primary advantage of a double girder gantry crane over a single girder?
A double girder crane offers greater stability, higher lifting capacity, and faster lifting speeds. It is the preferred choice for heavy-duty applications (typically over 20 tons) and for wider spans where load stability is critical.
2. Can this crane be used for handling shipping containers?
Yes, with the addition of a specialized container spreader attachment, this gantry crane is an excellent solution for loading, unloading, and stacking ISO containers in ports, rail terminals, and logistics hubs.
3. Is this crane suitable for outdoor use?
Absolutely. It is designed and built to withstand outdoor environments. We use durable paint and can add protective rain covers for the hoist and electrical systems to ensure long-term performance in all weather conditions.
4. What kind of runway track is required for this crane?
This crane runs on steel rails (e.g., P38, P43, QU70) installed on a suitable concrete foundation. Our technical team can provide the specific rail and foundation requirements based on the crane’s capacity and your site conditions.
5. How do I get a customized crane for my facility?
