ABSTRACT:
A method for controlling the lateral displacement of a trolley supporting goods to be unloaded at an unloading location, the goods being releasably attached to the trolley by an elongated flexible member. The method is characterized in that the trolley, which supports the goods, via the elongated flexible member during a first phase of the unloading operation, is decelerated from a certain lateral displacement speed at which it approaches the unloading station and, at least after part of the unloading operation of the goods, is accelerated in the opposite direction, whereby the retardation phase and the acceleration phase are invidually carried out within less than one period of the pendulum motion of the elongated flexible member. The method can be used in cases where the length of the flexible member varies during the approach of the goods to the unloading location.
