Einrichtung zur Erfassung der momentanen Belastung von Fördermitteln, insbesondere von Hubwerken

摘要

The device includes a load measuring device, and an electric motor 1 as a drive mechanism for lifting and lowering a carried load. The electric motor is in the form of a three-phase current asynchronous motor. The load measuring device can detect the power of the motor with a current and voltage measurement. This is compared with a reference power to determine the instantaneous loading. The reference power is a computer derived power of the motor to drive a nominal carried load. The instantaneous load may be formed from the ratio or the difference between the measured power and the reference power. A display device (10) may be provided to display the instantaneous load.
