Suspension Crane Skew Detection and Correction

The patent replaces complex electronic sensors and control systems with a simple mechanical detection device consisting of a sensor device that directly measures the skewed position of the crane bridge relative to the running gear. This mechanical approach achieves sufficient measurement precision without requiring complex electronics, thereby reducing device complexity while maintaining adequate skewing detection accuracy.

The sensor device is integrated directly into the running gear structure, allowing it to self-measure the skewing of the crane bridge relative to itself. This self-referential measurement approach eliminates the need for separate complex measurement systems and reduces overall device complexity while providing accurate skewing detection.

The patent employs a simple, inexpensive sensor device that can be easily manufactured and replaced if needed, rather than using expensive, high-precision electronic sensors. This approach prioritizes ease of manufacture and maintenance over maximum measurement precision, achieving sufficient skewing detection capability through a manufacturable mechanical solution.

By using a mechanical sensor device integrated into the running gear rather than complex electronic measurement systems, the patent achieves adequate measurement precision while significantly improving ease of manufacture. The mechanical design allows for simple fabrication and assembly without requiring sophisticated manufacturing processes.
