Single Girder vs Double Girder Overhead Crane

Choose the bridge arrangement by capacity, span, hook approach, building height and duty class.

When single girder fits

For suitable loads and spans it can provide a compact bridge, lower structural demand and accessible service arrangement.

• Suitable capacity range
• Compact bridge
• Balanced investment
• Under-running hoist

When double girder is relevant

Higher capacity, wider span, improved hook approach, maintenance platform or demanding duty may justify a double girder system.

• Higher capacity
• Wider span
• Top-running trolley
• Maintenance platform option
