- 15 - Abstract of the disclosure Closed-loop control monitoring system for a rope hoisting installation A closed-loop control monitoring system for a rope hoisting installation with an electric driving motor, especially for a deep hoisting installation and/or with a nonmetallic rope, in which, to avoid the occur- rence of oscillations of the moved masses of the rope and the load through changes in this speed of the load, variations in the rotational speed of the driving motor or emergency mechanical braking, the setpoint values of the control, designed as a reference variable control, are continuously adapted to the longitudinal oscillation behavior of the system or of one of its main components to avoid or at least reduce oscillation, and the continuous, proper operation of the adaptation and the extent of residual errors, resulting for example from transverse forces, are monitored and likewise compensated by monitoring and measuring devices.
