LOAD ERROR CORRECTING DEVICE AND LOAD ERROR CORRECTING METHOD FOR WORKING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a working machine for allowing simple and easy attitude changing work for a boom or an arm to find unknown quality by reducing the unknown quality for finding the weight of and the gravity center position of each of the boom, the arm and a bucket when correcting an error.;SOLUTION: In this load error correcting method, a weight error ΔWbm of the boom 4 and a weight error ΔWam of the arm 5 are introduced in accordance with a load error ΔWG as a suspending load in a non-loaded condition measured in each of first, second and third attitudes to reduce the unknown quality to be found. Thus, the method can be executed with the measurement in the three attitudes less than conventional ones.;COPYRIGHT: (C)2008,JPO&INPIT
