To provide a soundness evaluation method for a mechanical continuous unloader conveyor capable of accurately evaluating soundness of the unloader conveyor at actual operation (at cargo work).
In the soundness evaluation method for the mechanical continuous unloader 10, a ratio of a power calculation value calculated by product of conveying height of a load and a conveying speed and a mass at the operation of the unloader conveyor at beginning of delivery or beginning of maintenance and a power measurement value, i.e., a value obtained by adding a disturbance value at the operation relative to the power calculation value is previously determined. This is made as a reference value. A ratio of a power calculation value of the unloader conveyor at execution of work and a power measurement value is determined in imitation of the calculation of the reference value. This is made as a calculation value. Difference of the reference value and the calculation value is determined and the soundness of the unloader conveyor is evaluated by this value.
