When it comes to machine width, the VLM and vertical carousel are essentially the same. However, VLMs can be twice as deep as vertical carousels, which gives them an overall narrower footprint.
VLMs vary in height depending on the storage capacity needed for your facility; they start at 8 feet tall and can be installed up to 98 feet high. On the other hand, vertical carousels are shorter—starting at 7 feet tall and expanding to 32 feet high.
Although both machines can be built up, it doesn’t mean it’s always necessary. As the machine grows in height, the slower the throughput because it has more ground to cover. Therefore, when choosing the height of your vertical storage solution, it’s crucial to identify how much storage space you need and how quickly you need to retrieve items.
Vertical lift modules can carry up to 2,200 pounds per tray compared to vertical carousels that can handle up to 1,430 pounds per carrier. If you’re looking to store heavier loads, VLMs would be the better option for your facility.
