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
