From lifting skyscraper beams to aligning space telescopes, slewing drives deliver unmatched load capacity and motion control. Here’s how they transform industries:


1. Renewable Energy: Solar & Wind

  • Solar Tracker Drives:

    • Specs: 1-5 kNm torque, IP66 rating, 0.05° backlash

    • Case Study: NEXTracker’s SF7 system uses 2 drives/tracker, boosting energy yield by 25% vs fixed arrays.

  • Wind Turbine Yaw Drives:

    • Load: 80+ kN axial load + 50 kNm moment

    • Solution: 4x drives with fail-safe brakes (EN 81-20 compliance).

2. Construction Cranes
  • Requirements:

    • Torque: 15,000-40,000 Nm

    • Slew speed: 0.1-1.2 RPM

  • Success Story: Zoomlion’s T1800 crane uses dual-drive redundancy – zero downtime in 5 years of operation.

3. Robotics & Medical Equipment
  • Surgical Robots:

    • Precision: ±0.02° backlash

    • Cleanroom rating: ISO Class 5

  • Packaging Robots:

    • Cycle rate: 3 seconds/rotation

    • Maintenance-free life: 10,000 hours (DIN 3990 standard).

4. Defense & Aerospace
  • Radar Platforms:

    • Wind load resistance: 150 mph

    • Operating temp: -40°C to +85°C

  • Missile Launchers:

    • Shock resistance: 100g (MIL-STD-810G).
