Definitions

  • the electronic damper as a first input quantity, a target rotational speed of the sprocket and a second input quantity, an actual angle of the sprocket are supplied and in the electronic damper from the two input variables, a damping control variable is calculated in the form of a Subdued speed is passed to the electric motor.
  • an empirical optimization of the damping control variable is achieved in that at least sensor detects the effect of a building resonant vibration and, if necessary, the damping control variable is changed.
  • FIG. 2 shows a force-time diagram of the polygon-excited chain oscillation of a chain hoist according to the prior art.
  • a force-time diagram of the polygon-excited chain oscillation of a chain hoist according to the invention is shown in FIG. It can be seen that over the time shown in the x-axis from 0 to about 11 seconds, in which a trial load lifting operation is carried out, the fluctuation width of the y-axis applied chain force amplitude of up to about ⁇ 700N by the present invention electronic damper 8 can be reduced to about ⁇ 70N. As a result, a smooth running of the chain and a lower threshold load of the chain hoist is achieved.
