摘要
During transfer of a material by a hydraulic excavator, load computing means periodically computes the weight of the material in a bucket of the excavator. Average value computing means computes an average value of weights of the material including a currently computed weight and a predetermined number of weights computed prior to the currently computed weight (M6), and standard deviation computing means computes, based on the average value, a standard deviation of the weights of the material (M7). True load value determining means selects a minimum standard deviation from among the standard deviations computed by the standard deviation computing means from the start of the transfer of the material to a different location until the end of the transfer of same, and judges the average value based on which the minimum standard deviation was computed, to be a true value of the weight of the material (M10, M11).
