SYSTEM FOR MEASURING THE RACK LENGTH OF GANTRY CRANE AND THE METHOD THEREOF

摘要

How to measure the length of the rack of the gantry crane is provided. How to measure the length of the rack of the gantry crane according to one embodiment includes: (a) providing a means for taking up the rack and the rack moves along the gantry crane; (B) providing a reference position provided in the extending direction of said rack means; (C) measuring the distance to the reference position of the reference location providing means; (D) comprises the step of measuring the distance between the measurement starting point and measurement end point, (d) step, (d1) if the measurement start point and the measurement end point between the reference position means a location service, the moving the recording means while measuring the absolute length of the measurement end point from the reference position of the reference position after providing means, the distance to the reference position and measure the absolute value of the measured length to the measurement end point from the reference position If the summing by measuring the distance between the measurement starting point and measurement end point, and (d2) measuring the measurement start point and the end point reference position between the providing means are not located, the measurement while moving the recording means and from the start point includes the step of measuring the absolute length of the end point of the measurement. ;
