ABSTRACT:
The invention relates to a method for loading and unloading large area transporters, such as ships or the like, using a vertically spirally curved conveyor connected to the goods loading and unloading apparatus. The goods to be conveyed are discharged from or placed on a pivotable and optionally telescopable horizontal conveyor arranged on its lower end portion. During loading and unloading, the goods transfer spiral which is in fixed operative connection with the horizontal conveyor is moved over the complete pivoting area in congruent manner to the lower spiral conveyor segment of the vertical conveyor. The goods transfer spiral is moved beneath the lower spiral conveyor segment for loading purposes and above the lower spiral conveyor segment for unloading purposes in such a way that an overlapping zone is always formed between the lower spiral conveyor segment and the goods transfer spiral.
