Abstract
An object of the present invention is to provide a new load measuring apparatus for a construction machine that enables more enhancing measurement precision by monitoring a condition of a suspension cylinder. The load measuring apparatus for a construction machine according to the present invention is provided with a loading weight arithmetic modulethat calculates a loading weight on the basis of loads of plural suspension cylindersand a loading weight confirmation modulethat outputs the calculated loading weight when the loads of the suspension cylindersare all equal to or larger than a specified value and makes the calculated loading weight ineffective without outputting the loading weight when any one of the loads is below the specified value.
