Method for acquiring position correction amount of waste plate

摘要

PROBLEM TO BE SOLVED: To easily and accurately acquire a position correction amount between a position measuring device arranged on a vehicle body of a construction work machine and a cutting edge of an earth removing plate.SOLUTION: The present invention is a method for acquiring position correction amount C between a position of a cutting edge 121 of an earth removing plate 120 arranged on a vehicle body 110 of a bulldozer 100 via a connecting portion 130 and a position acquiring device 210 arranged on the vehicle body 110. The position of the position acquiring device 210 and the position of each part of the bulldozer 100 are measured by a measuring devices 220 arranged on both sides of the bulldozer 100 in a lateral direction (step ST2), and from these measured values, the position correction amount C from the position acquiring device 210 to the position of the cutting edge 121 of the earth removing plate 120 is calculated (steps ST3 to ST6).SELECTED DRAWING: Figure 5
