Description

  The present invention relates to a pallet support frame that can be compactly nested, even when angled columns are used.

  In a warehouse that stores and manages luggage, the luggage is placed on wooden or plastic pallets, and the pallet on which the luggage is placed is transported and stored by a forklift. A pallet support frame is used to efficiently arrange and store the pallet vertically and horizontally. The structure of a general pallet support frame is described, for example, in Patent Documents 1 and 2.

  On the other hand, since the pallet support frame in a state where pallets are not stacked occupies space in the warehouse if it is installed as it is, it is disassembled or nested (stacked) and moved outdoors. The structure of the nestable pallet support frame is described, for example, in Patent Document 3 and is marketed under the name Nesrac (registered trademark).
