LOAD MEASURING APPARATUS AND MEASURING METHOD USING CONSTRUCTION MACHINE

PROBLEM TO BE SOLVED: To easily, promptly and more accurately measure the load of a hydraulic cylinder required for measuring the weight of an object to be measured.SOLUTION: An object to be measured, which is held by a fork grapple 14 of a work device 10, is carried up to a predetermined height position by performing a boom-up operation of a boom cylinder 15, stopped and then temporarily operated in a boom-down direction by the boom cylinder 15. Next, this boom-down operation is stopped and after the lapse of a little time, the boom cylinder is commanded to be adjusted down in the boom-down direction from a controller 25. When this control-down command is outputted, the boom is not moved or downward operation is performed just for s shorter stroke than boom-down operation.
