Critical Slewing Device Diagnostic and Technical Inspection of Flender CFA 200

High-precision on-site diagnostic of a 487 kW power generation gearbox, identifying a structural failure in the slewing mechanism and providing a comprehensive restoration roadmap for reliable equipment startup.

We executed a specialized on-site technical inspection and forensic measurement of a Flender CFA 200 gearbox, a parallel shaft unit operating within the power generation sector. With a rated power of 487 kW, this gearbox is a vital link in the energy production process, where mechanical integrity is essential for safe and efficient operation.

During the detailed condition assessment, Wikov specialists identified a cracked hollow shaft within the slewing device—a critical structural failure that posed a significant risk to the entire drive train. To prevent a catastrophic breakdown, Wikov provided a comprehensive expert recommendation for the replacement of this specialized mechanism. Our service team also outlined the necessary engineering steps to ensure a smooth and safe mechanical start-up of the power generation equipment following the repair. This intervention highlights Wikov’s ability to detect hidden structural defects and provide the technical expertise required to return high-value assets to peak operational condition, ensuring long-term grid stability.
