Why Choose a Double Girder EOT Crane?
If you’re evaluating single girder vs double girder EOT cranes, understanding the differences is essential for selecting the right equipment.
Key advantages:
- Higher lifting capacity – From 5 tons up to 800 tons
- Greater stability and rigidity – Twin-beam structure minimizes vibration
- Longer spans – Up to 31.5 meters
- Higher hook height – Better vertical space utilization
- Ideal for frequent duty cycles – Designed for A5, A6, and A7 classes
For applications requiring 25-ton double girder EOT cranes or higher capacities, the double girder configuration provides superior performance and longer service life.
Wide Range of Applications
Double girder electric overhead travelling cranes are widely used in:
- Metallurgy & Heavy Industry: Steel mills, foundries, heavy material handling

FAQs About Double Girder Electric Overhead Travelling Crane
A double girder electric overhead travelling (EOT) crane is a heavy-duty crane with two parallel girders supported by end trucks, with a hoist trolley running on top. It is designed for heavy lifting and long-span operations.
Typically 5–250+ tons (custom models can exceed this range).
- LH Type: Electric hoist trolley (medium–heavy duty)
- QD Type: Winch trolley (very heavy loads)
- QE Type: Dual trolley (metallurgical applications)
- Custom Types: Explosion-proof, heat-resistant, automated
- Daily: Visual inspection, brake check, lubrication
- Weekly: Trolley/wheel alignment, cable inspection
- Monthly: Gearbox oil, bolt torque, limit switches
- Annual: Full inspection, load test, wear measurement
- Motor won’t start → Check interlock, relay, wiring
- Abnormal noise → Inspect bearings/gears, lubricate
- Brake failure → Replace pads, adjust clearance
- Unstable hoist speed → Check inverter, load, lubrication
- Bridge skew → Adjust wheel diameter and drive system
- Add 10–20% safety margin to maximum load
- Include lifting attachments (grab, magnet, etc.)
- Ensure crane capacity ≥ actual working load
