Description

Technical field The invention relates to a heavy-duty stacking column for receiving heavy loads according to the preamble of claim 1. State of the art Heavy-duty stacking columns of this type are already known and commonly used in a variety of forms and designs. These heavy-duty stacking columns are used particularly in the automotive industry to temporarily store sheet metal parts that come from a molding plant and need to be transported for further processing. In this context, reference is made to the DE 93 18 410 U1 The document refers to a stacking column in which the latch levers are equipped with springs that move them from their support position to their catch position or to their rest position when unloaded. Transverse stop pins are provided in the tower body as rotation stops for the latch levers' retaining arms in the locking position. The latch levers are identical, and the support arm and retaining arm are of the same width and aligned with each other. However, a disadvantage of the stop pins is that, in practice, the circular profile of these pins repeatedly causes them to break, bend, or cause the latch levers to bend under heavy loads and the acceleration forces that occur during transport. A similar construction is also shown in the DE 29 30 053 A1 Circular bearing bolts are also used there, which are actually only inserted into the corresponding side walls as needed to provide support, and again only in the rear area of the latch. Here too, high weights lead to the disadvantages described above. Further information will be provided on the DE 298 08 971 U1 Reference was made to designs that incorporate a shock-absorbing and elastic material made of plastic or rubber on the latch levers themselves to absorb the resulting forces. This is not feasible for heavy loads weighing several hundred kilograms to several tons, as the amount of shock-absorbing material required would be far too large to effectively secure such a heavy load, for example, during transport. There are vertical stacking columns, but also horizontal or inclined ones, which are likewise subject to the present invention. For loading such stacking columns, latches have proven very practical. These latches are connected in such a way that they move from a rest position to a working position when the stacking column or rack is filled with these stacking columns. This process usually begins by placing a workpiece on the bottom latch, which rotates the bottom latch into the working position. This rotation causes the bottom latch to move the next latch into a ready position, where it can receive the next item. Upon receiving the next item, the following latch is again rotated into the ready position. Outside of the ready and working positions, the latches are in a rest position, for example, between two side plates of the stacking column. Such a stacking column can be found, for example, in the DE 20 2020 104 669 U1 described. Further information will be provided on the EP 1 505 010 A1 The document discloses an automated structure for storing and handling products, consisting of numerous interconnected shelf sections arranged in a column and designed to accommodate products placed upon them. Mechanical connecting elements are provided to allow the shelf sections to move sequentially, one after the other. This movement includes a horizontal position where the product is stored on the shelf section, an intermediate position for receiving the product, and a near-vertical resting position. Further information will be provided on the US 2019 / 0 077 602 A1 It should be noted that a stacking column for stacking and transporting vertically separated items comprises a multitude of pivoting brackets arranged one above the other, designed to support the items and connected to corresponding counterweights. The central section of each bracket has a pair of eyelets for a pivot pin and a pair of stop fins that fit into corresponding grooves provided on the column body. The rear section of each bracket is provided with at least one lateral projection coupled to two counterweights. One of the counterweights is connected to the lateral projection of the bracket below, and the other to the lateral projection of the bracket above. Finally, we will also mention the DE 10 2024 104 302 A1 The document describes a stacking column for storing automotive electric batteries, either stacked or side-by-side, on or against latches. The latches are housed in a U-shaped structure, which has two side walls, a back wall, and an opening edge. The latches rotate about axes from a rest position to a working position between the two side walls and have a support element on one side of the axis and a back element on the other. In the working position, the latch rests with its back element against a polygonal bolt stop, which is located on the back wall between the two side walls. The support element rests on a polygonal bolt bearing, which is located on the opening edge b
