Frequently Asked Questions

What is a multi level shuttle AS/RS?
A multi level shuttle AS/RS is a tote and crate storage system in which one shuttle serves several rack levels from a single aisle, instead of one shuttle per level. Addverb's Medius handles loads up to 66 lb, travels at up to 10 ft/s and reaches 7 storage levels per aisle with double-deep storage. Paired with a goods-to-person station, it brings stock straight to associates. -
What is the difference between a multi level shuttle and a carton shuttle?
A multi level shuttle serves several rack levels with one vehicle, while a carton shuttle typically runs one shuttle on each level and relies on separate vertical lifts to move loads between levels. Addverb's Medius reaches 7 levels per aisle, so you need fewer vehicles for the same storage, which suits moderate throughput. Addverb's Quadron runs a shuttle per level for higher throughput and loads up to 110 lb. -
How much storage density does a multi level shuttle provide?
Addverb's Medius multi level shuttle stores about 3.3 totes per square foot of floor space, using double-deep racking up to 66 ft high to make full use of a building's clear height. That holds far more SKUs in the same footprint than static shelving with picker aisles, and narrow aisles often let the system fit inside an existing building. -
How many totes per hour can a multi level shuttle handle?
Addverb's Medius multi level shuttle is rated at 103 totes per hour on a 98 ft track, with loaded and empty speeds of up to 10 ft/s. Several aisles operate in parallel, so system throughput scales with aisle count. Medius also sequences retrievals so pick stations receive totes in order, which helps US fulfillment centers through peak season. -
Can a multi level shuttle be used for goods-to-person order picking?
Yes, Addverb's Medius multi level shuttle retrieves totes and crates and delivers them to a goods-to-person station, so associates pick orders at one ergonomic workstation instead of walking aisles. The system follows a programmed sequence for storage and retrieval, which keeps order release predictable. Medius integrates with existing warehouse automation, so it can feed packing, sortation or conveyor lines downstream.
