CONSTITUTION: Oil pressure sensors 22, 23, 24 are provided at various sections, and a controller 25 compares the excavating force calculated from the detected value of the oil pressure sensor 23 (excavating force equivalent pressure + chain tension equivalent pressure) and the detected value of the oil pressure sensor 24 (chain tension equivalent pressure) with the excavating force target value and controls the lateral excavating speed of an excavating device to obtain the prescribed speed target value. The excavating force target value is updated in sequence based on the compared result between the lifting force calculated from the calculated excavating force and the detected value of the oil pressure sensor 22 (lifting force equivalent pressure excavating force equivalent pressure) and the lifting force target value, the lifting force is made coincident with the target value, the delivery quantity of the bulk cargo is made constant, and the fixedquantity delivery control can be surely performed.
