Bridge and trestle crane rail inspection system;

Development of single-rail robot for crane rail inspection

A single-rail inspection robot is developed according to the work condition of bridge and trestle cranes rail.

Compared with traditional monitoring system, a new method of acceleration measurement was used for more accurate estimation of vibration source, so the accuracy and reliability of track detection were raised.

An introduction is given to the importance of track detection and maintenance technology in keeping the evenness of tracks, advanta ges and disadvantages of current track detection technology in China and develop ment trend, and scope and method of detection.
