This study introduces a novel terrestrial laser scanning (TLS) method for precise crane rail geometry measurement. The technique accurately assesses deviations and compliance with Eurocode 3, offering an alternative to traditional methods.
Area of Science:
- Geomatics Engineering
- Civil Engineering
- Structural Monitoring
Background:
- Accurate measurement of crane rail geometry is crucial for structural integrity and operational safety.
- Traditional measurement methods can be time-consuming and less precise for complex geometries.
Purpose of the Study:
- To present a new method for measuring crane rail geometry using terrestrial laser scanning (TLS).
- To define and compute positional and altitude deviations, span, and height differences of crane rails.
- To verify compliance with Eurocode 3 standards.
Main Methods:
- Terrestrial Laser Scanning (TLS) techniques, including pure TLS and hybrid TLS.
- Segmentation of rail lines and adjustment of their planes.
- Definition of characteristic rail lines and computation of geometric parameters from profiles.
Main Results:
- The developed TLS method accurately measures rail geometry, including deviations and span.
- Analysis of segment length and point density influence on measurement accuracy.
- Comparison of TLS results with the classic polar method demonstrates high precision.
Conclusions:
- The presented TLS method provides a precise and detailed approach to measuring crane rail geometry.
- The method offers an original contribution by detailing computations without relying on existing software.
- The study validates the effectiveness of TLS for structural monitoring of industrial infrastructure.
