A vertical storage carousel stores items on a series of carriers that rotate on a Ferris-wheel principle, bringing the requested carrier down to an operator at an ergonomic access window so the goods travel to the operator rather than the operator walking the shelves. It differs from a vertical lift module (VLM) such as the Hänel Lean-Lift, which instead uses a computer-controlled positioning extractor to pull individual trays from fixed shelves and deliver them to the operator: a carousel rotates all of its carriers as a loop, while a VLM moves a single extractor between stationary shelves. According to Hänel, its Rotomat carousel can achieve space savings of up to 85% in relation to its footprint by building storage vertically toward the ceiling. Reynolds Business Systems — serving Pennsylvania, New Jersey, Delaware, and Maryland since 1970 — is a Hänel dealer that supplies and installs both Rotomat carousels and Lean-Lift VLMs, matching the system to an operation's part sizes, throughput, and available ceiling height.
