Patent ID: 11668087

Abstract:
A storage system includes a storage grid structure; and a remotely operated storage bin handling vehicle. The storage grid structure comprises a first and a second type of vertical storage column profiles defining multiple storage columns in which storage bins can be stored one on top of another in vertical stacks. The first and second type storage column profiles are interconnected at top ends thereof by rails forming a horizontal rail grid upon which the remotely operated storage bin handling vehicle may move in two perpendicular directions. The first type of storage column profiles has a cross-section comprising a hollow centre section and four corner sections, each of the four corner sections of the first type of storage column profiles comprises two perpendicular bin guiding plates for accommodating a corner of a first storage bin. The second type of storage column profiles has a cross-section comprising a hollow centre section having at least two connecting elements arranged in, or on, an external surface of the hollow centre section, and at least one corner section, the at least one corner section of the second type of storage column profiles comprises two perpendicular bin guiding plates for accommodating a corner of a second storage bin. The storage grid structure comprises a grid supporting structure comprising at least two of the second type of storage column profiles interconnected, via the at least two connecting elements of the at least two second type of storage column profiles, by vertically inclined support struts.
