Kind Code:
A1
Abstract:
A calculated load value (CalcuPayload) for the interior of a bucket (3c) is calculated on the basis of a boom cylinder (4a) load. The variation (X) per unit time for information representing at least one of an operation command value to operate the boom cylinder (4a) and the telescoping speed of the boom cylinder (4a) is detected. A load value (Wpayload) is determined by correcting, on the basis of the variation (X) per unit time, the calculated load value (CalcuPayload) obtained by the calculation.
