<p>The stack linkage (1) has multiple similar shopping trolleys (2), which are pushed into each other. The spacers are attached to the shopping trolleys of the stack linkage defined for the collection place. The stack distance is formed between the shopping trolleys by the spacer. The stack distance is more than the stack distance, which is formed between the shopping trolleys of the stack linkage defined for the transport. The length of the stack linkage defined for the collection point is bigger than the length of the stack defined for the transport.</p> |
