In the work of engineering, traveling gantry crane traveling legs prone to skew problems. So in some traveling gantry crane will be equipped with a correction system, display, offset detection and correction functions.
Correction system can display the traveling legs distance, traveling mechanism position after measurement, calculation.
When traveling gantry crane working, the correction system will start working together, the faster support legs will transfer a data to the correction system, the system will display the problem.
If the shift value of legs reach the user-set value, the system will generate a warning signal and output the erro value. If the deviation exceeds the 3 / 1000th of the traveling gantry crane span, the system will automatically disconnect the running circuit, only manual correction then can work again.
In general, the traveling gantry crane correction system has the functions of recording position, power failure memory, debugging, alarm, black box and others.
