Vertical Lift Modules (VLM)
VLMs allow for very dense storage of small parts. The system’s ability to store and retrieve parts based on part number makes it a very efficient way to fill orders since the parts are delivered to the picker without the need to lookup locations or walk to a storage bin. This goods-to-man functionality and reasonably high retrieval speed has allowed these lifts to be used for distribution. Pick rates of over 100 lines/hour are not uncommon in a paired VLM environment once picklist automation is used to send orders directly to the lifts.
