In the synchronisation control device for a plurality of drive units which are operated simultaneously, for example in lifting systems, in the case of which each drive unit has a motor having in each case one sampling element for which, in turn, a rotation-angle switch is provided, a timer (Z<i>) is provided which delays the switching off of individual drive motors (M<i>) by a predetermined time interval (Tv) and is in control connection with the rotation-angle switch (G<i>) of each drive unit (E<i>) and the associated power circuit breaker (LS<i>), this timer (Z<i>) being adjustable so that the signal (corresponding to one or more complete revolutions) from the rotation-angle switch (G<i>) can in each case be selected as a rotation-angle signal which is associated with tripping, as a result of which simple construction of the control circuit is achieved. <IMAGE> |
