PROBLEM TO BE SOLVED: To provide a load amplified loading device such as a load testing machine of an operating lever type and a load amplified loading method with which it is possible to apply a large load, for example, exceeding 50 t while maintaining high accuracy.SOLUTION: The load amplified loading device comprises: a weight booster lever 3 for amplifying the load of a weight loaded to an important point and having a known mass and outputting from a power point; component force means 4 for separately conveying the force loaded on the power point of the weight booster lever 3; a plurality of component force booster levers 5 (5A, 5B) forming a pair for amplifying the component forces and outputting the same from the power point, with each of the component forces divided by the component force means 4 loaded on the important point; a resultant force ring 6 for combining the forces outputted from the power points of the plurality of component force booster levers 5 (5A, 5B); and resultant force conveyance load means 8 for conveying the forces combined by the resultant force ring 6 and conveying the same to an object to which a load is to be applied.SELECTED DRAWING: Figure 1 |
