Storage and retrieval system, high-bay warehouse, storage method and retrieval method

A storage and retrieval system for a high-bay warehouse, the system comprising:

• a superordinate control computer having a communication module;
• and
• at least two self-driving gangway vehicles that are non-mechanically interlinked, comprising a control apparatus with a communication apparatus, of which at least one of the communication apparatuses is designed to communicate bidirectionally with the communication module of the superordinate control computer;
• wherein the control apparatus of the gangway vehicles prompts a drive apparatus of the gangway vehicles to drive into or drive out of warehouse gangways of the high-bay warehouse,
• wherein a measurement of the path covered by the respective gangway vehicle is carried out via a path measurement apparatus that is in a communication connection with the control apparatus,
• wherein the control apparatus of the gangway vehicles is designed to prompt a lifting apparatus of the gangway vehicles to adjust a load receiver between a raised and a lowered position, and
• wherein the superordinate control computer prompts the gangway vehicles, on the basis of the data from the path measurement apparatuses fed back thereto by at least one of the control apparatuses, to raise, synchronously transport, and put down only part of a common loading unit at a distance from each other.
