<p>The invention relates to a method for the dynamic detection of a faulty operation of a load lifting device, wherein the load lifting device has a force sensor, comprising the following steps: monitoring a signal of the force sensor for an increase; defining a time period required for lifting the load receiving means; monitoring the signal for an exceeding of the overload threshold; if the overload threshold is not exceeded during the defined time period, determining a weight force within the defined time period from the signal, and establishing the weight force determined as a base load; establishing a dynamic jump threshold as the nominal overload threshold, which is greater than the base load and smaller than the current overload threshold; and monitoring whether the signal is greater than or equal to the jump threshold, and generating a switch-off signal, if the signal is greater than or equal to the jump threshold.</p> |
