London Eye Engineering – Structure & Systems
How the London Eye works: spoke cables, hub axle, bearings, control systems, foundations and wind load management.

The Eye behaves like an enormous bicycle wheel: a rim stabilized by tensioned spokes anchored to a hub and giant A‑frame.
1) Structural Anatomy
| Component | Function |
|---|---|
| Rim | Carries capsule loads and transfers forces to spokes |
| Spoke Cables | Tensioned elements stabilizing the rim |
| Hub + Spindle | Central axle assembly distributing loads |
| A‑Frame + Backstay | Supports the wheel, resists overturning |
| Foundations | Transfer loads into the riverbank ground |
2) Rotation & Controls
- Rotation ~30 minutes per cycle; speed low enough to allow boarding without full stops in normal conditions.
- Drive systems and brakes are redundantly configured; operators can pause for accessibility boarding.
3) Wind & Weather
- High winds increase dynamic loading; thresholds trigger slow/stop procedures.
- Lightning protection and continuous monitoring layer safety margins.
4) Maintenance
- Bearings, cables and fasteners undergo scheduled inspections.
- LED lighting and control firmware receive periodic upgrades.
Bottom Line
Tension, redundancy and conservative wind policies make the Eye both elegant and reliable.
