Hydroelectric Generator Turning Gear
Hydroelectric Generator Turning Gear
The SDPC Hydroelectric Generator Turning Gear is specially designed for the installation, inspection, maintenance, and overhaul of hydroelectric generator units in hydropower plants.
The system provides controlled rotation of large hydro-generator rotors, allowing maintenance personnel to safely inspect rotor alignment, concentricity, air gaps, and other critical clearances. By replacing manual turning methods, the turning gear improves maintenance efficiency, reduces labor requirements, shortens outage periods, and enhances overall operational safety.
Engineered for megawatt-class hydroelectric generating units, the SDPC turning gear delivers high torque at low rotational speeds, ensuring smooth and precise rotor positioning during maintenance activities.
Key Features
