The stacking storage arrangement includes multiple container receiving spaces and a loading space arranged below the container receiving spaces. A loading vehicle that is movable in the loading space includes a chassis and a container seat that is height-adjustable relative to the chassis. A holding device is arranged between each container receiving space and the loading space and a hold-open device is arranged on the chassis separately from the container seat. ## Claims ### Claim 1 A stacking storage arrangement comprising: multiple container receiving spaces; a loading space arranged below the multiple container receiving spaces; a loading vehicle that is movable in the loading space, the loading vehicle comprising a chassis and a container seat that is height-adjustable relative to the chassis; a frame arrangement located between the multiple container receiving spaces and the loading space; a holding device that is coupled to the frame arrangement and arranged between each container receiving space and the loading space, the holding device being positionable in an opened or a closed position; a fixing element that is pivotably coupled to the frame arrangement to engage the holding device in the opened position; and a hold-open device arranged on the chassis separately from the container seat, the hold-open device having a pivotable actuating lever arranged to cause the fixing element to engage the holding device in the opened position. ### Claim 2 (depends on 1) The stacking storage arrangement according to claim 1, wherein the holding device comprises multiple holding elements, and wherein the hold-open device includes a number of hold-open elements that corresponds at least to a number of the plurality of the holding elements. ### Claim 3 (depends on 1) The stacking storage arrangement according to claim 1, wherein the hold-open device comprises a drive arrangement arranged on the chassis. ### Claim 4 (depends on 3) The stacking storage arrangement according to claim 3, wherein a force-limiting device is arranged between the drive arrangement and the pivotable actuating lever. ### Claim 5 (depends on 3) The stacking storage arrangement according to claim 3, wherein the drive arrangement comprises a preloaded drive element and a motor that acts on the drive element against the preload. ### Claim 6 (depends on 5) The stacking storage arrangement according to claim 5, wherein the motor is embodied as a rotary motor. ### Claim 7 (depends on 1) The stacking storage arrangement according to claim 1, wherein the hold-open device is arranged outside of an opening that connects the container receiving space with the loading space. ### Claim 8 (depends on 1) The stacking storage arrangement according to claim 1, wherein the holding device comprises at least one holding element and the fixing element is movable between a first position, in which the fixing element engages the at least one holding element in the open position, and a second position, in which the fixing element does not act on the at least one holding element, and wherein the fixing element is actuatable by the hold-open device. ### Claim 9 (depends on 8) The stacking storage arrangement according to claim 8, wherein the fixing element is pivotably mounted. ### Claim 10 (depends on 8) The stacking storage arrangement according to claim 8, wherein the fixing element is preloaded into the second position. ### Claim 11 (depends on 1) The stacking storage arrangement according to claim 1, wherein the loading vehicle further comprises an unlocking device for releasing the holding device. ### Claim 12 (depends on 1) A method for operating in the stacking storage arrangement according to claim 1, comprising: moving the loading vehicle into the loading space; lifting the container seat upwardly toward the container receiving space, wherein the container seat lifts at least one container within the container receiving space and wherein the holding device for supporting the at least one container is moved; and lowering the container seat and moving the loading vehicle out of the loading space. ### Claim 13 (depends on 12) The method according to claim 12, wherein, when the container seat is lowered, the at least one container is supported on the container seat. ### Claim 14 (depends on 13) The method according to claim 13, wherein the at least one container is supported by the holding device in the container receiving space while the loading vehicle is moved into the loading space, and the method further comprises: while lifting the at least one container in the container receiving space, moving the holding device into an open position; actuating the hold-open device to fix the holding device in the open position; lowering the at least one container past the holding device in the open position to remove the at least one container from the container receiving space; and deactivating the hold-open device, whereby the holding device moves into a closed position after the at least one container is lowered below the holding device. ### Claim 15 (depends on 13) The method according to claim 13, wherein the at least one container removed from the container receiving space comprises multiple containers removed from the container receiving space at a same time. ### Claim 16 (depends on 12) The method according to claim 12, wherein, when the container seat is lowered, the container seat is empty. ### Claim 17 (depends on 16) The method according to claim 16, wherein the at least one container is supported on the container seat while the loading vehicle is moved into the loading space, and the method further comprises: contacting the holding device with the at least one container to move the holding device out of a closed position as the container is lifted in the at least one container receiving space, wherein, when a support surface of the at least one container is lifted above the holding device, the holding device returns to the closed position; and lowering the at least one container to be supported the holding device.
