Pallet racking systems are those warehouse racks that are often stacked a couple of stories high. They are most effective for storing goods and pallets of goods too. Most of them rely on an interlocking system to remain connected and erect, typically with a hook-and-bar system or with a round-headed peg and hole system. As you look for more pallet racking, you may come across teardrop pallet racking systems for sale. The misnomer is a bit confusing, as it sounds as though the racks are teardrop-shaped. Here is more info on these systems to help sort out the confusion.
No, the Racks Are Not Teardrop-Shaped
Have you ever seen racks that are teardrop-shaped? It just would not make sense, would it? There are racking systems that are similar to lockers in that each space is a vertical rectangle, and systems that look a lot like honeycomb hexagons, but teardrop-shaped racks would just not be very helpful for storing much of anything. Ergo, the racks themselves are not teardrop-shaped.
The Interlocking Metal Components Are Where the Teardrops Are
The main feature of these pallet racking systems is in the interlocking metal components. The vertical end pieces all have these special holes in them that look like inverted teardrops or backwards commas. The horizontal side supports for the shelves have inverted teardrop-shaped pegs. Just like the round pegs in the more common pallet racking systems, the "teardrops" fit through the openings in the vertical framework, slide down to lock into place, and cannot release without a lot of effort. Ergo, the teardrop pallet racking systems are named for their peg-and-hole configurations, and not for the shape of the shelves. Make sense?
Why the Teardrop Systems Are Becoming So Popular
The round peg systems sometimes have a tendency to slide up and out of they are knocked or bumped. That makes for somewhat dangerous shelving. The teardrop system cannot do this. As the teardrop peg fits through the teardrop hole and slides down, the fat round part of the peg becomes stuck in the short "tail" of the teardrop opening. It is locked hard into place, and only a rubber-headed mallet can knock the horizontal frame pieces up and out of the vertical frames.
This is especially useful considering the fact that these shelves often hold really heavy pallets of goods. With a heavy pallet on the shelf, nothing is going to knock these systems loose, not even a forklift. Consider replacing all of your old systems with teardrop systems today.
