PROBLEM TO BE SOLVED: To provide a method for measuring the load of hoisting with a crane by a power value which uses an inexpensive electric load meter and reduces a measurement time to increase the initial safety or operability of hoisting activation.SOLUTION: A first power measurement is made when a rate is low immediately after hoisting activation, a first load conversion is performed based on the measured power value, a second power measurement is made when a rate becomes higher, and a second load conversion is performed based on the measured power value.SELECTED DRAWING: Figure 2

    【課題】安価な電力式荷重計を利用し、かつ、計測時間の短縮化を行うことにより、巻上げ起動した初期の安全性や操作性を向上するようにした電力値によるクレーンの吊上げ荷重の測定方法を提供すること。【解決手段】巻上げ起動した直後の低速時に1回目の電力測定を行い、測定した電力値に基づいて1回目の荷重換算を行い、その後、加速した高速時に2回目の電力測定を行い、測定した電力値に基づいて2回目の荷重換算をする。【選択図】図2
