Hand-pushed flaw detectors, such as the UDS2-73 and UDS2-77, are used for confirmatory inspections following high-speed ultrasonic rail testing or for primary inspections of small track sections, tight-radius curves, station tracks, and other areas where high-speed systems are impractical or ineffective.
Applications
The OKOSCAN-73HS systems can be mounted on various chassis to meet diverse user requirements. A railway car or hi-rail truck with a dedicated cabin offers ample space for large displays and ensures comfortable working conditions for operators — essential for continuous inspection of extensive railway tracks.
The safety of railway operations across the globe relies significantly on the quality and integrity of the railway tracks. Tracks in good condition serve as the foundation for safe and reliable transportation, reducing the likelihood of accidents and ensuring smooth operations. Achieving and maintaining such safety standards in the most efficient and cost-effective manner involves the implementation of Risk-Based Engineering principles. These principles provide a structured framework for assessing and mitigating potential risks associated with railway tracks.

Manual Rail Inspection on the Track
Manual rail inspection on the track is used in two scenarios:
- As a confirmatory inspection of defects detected during continuous rail inspection using single-rail and double-rail flaw detectors or, in some cases, high-speed ultrasonic rail inspection systems.
- As an acceptance inspection of aluminothermic welded rail joints.
The middle link in the rail track quality management system (in the part of ultrasonic rail inspection) is the rails ultrasonic testing using hand-pushed ultrasonic rail inspection trolleys, also known as ultrasonic single-rail and dual-rail flaw detectors. This is the most widespread class of equipment used on all railways in the world.
