PURPOSE:To remove an output error generated at the time of unbalanced load or eccentric load and to obtain an accurately measured value by arranging an annular auxiliary member for measuring a load between a load meter and a bearing plate. CONSTITUTION:The auxiliary member 1 for measuring a load is an annular member arranged between the load meter 2 and the bearing plate 3. For instance, the member 1 consists of a steel material or the like and has a circular opening part 15 on its center. Since the kinds and size of the load meter 2, a jack, a jack chair, the bearing plate 3, a pedestal fittings, etc. are previously fixed, several auxiliary members 1 corresponding to these parts are previously produced and a member 1 having a proper shape is selected and used in accordance with the degree of unbalanced load and the kind of a machine to be used. Since the unbalanced load applied to the bearing plate 3 is turned to a level close to uniform load at the use of a smooth auxiliary member 1 and the influence due to the bend of the bearing plate 3 at an inclined surface part is absorbed at the use of an auxiliary member 1 having the inclined surface, respective output errors of the load meter 2 are removed. |
