Frequently Asked Questions

What is a carton shuttle ASRS?
A carton shuttle ASRS is an automated storage system in which rail-guided shuttles run along each rack level to store and retrieve cartons, crates and totes, while vertical lifts carry loads between levels. Addverb's Quadron handles loads up to 50 kg, travels at 4 m/s and supports single-deep or double-deep storage. It stores, buffers and sequences inventory, then delivers it to picking or packing stations. -
What is the difference between a carton shuttle and a miniload ASRS?
A miniload ASRS uses one crane per aisle to move totes both horizontally and vertically, while a carton shuttle splits those moves between shuttles on each level and separate vertical lifts. Because several shuttles work in the same aisle at once, a carton shuttle such as Quadron delivers more throughput per aisle. A miniload crane can suit heavier mixed loads and lower throughput needs. -
How many totes per hour can a carton shuttle handle?
Addverb's Quadron carton shuttle is rated at 115 totes per hour on a 30 m track, travelling at 4 m/s loaded or empty, and system throughput grows with every shuttle level you add. Every level works in parallel. Addverb sizes shuttles, lifts and pick stations together, since the lift or the station, not the shuttle, often sets the real limit at peak. -
How does a carton shuttle support goods-to-person picking?
A carton shuttle supports goods-to-person picking by retrieving the right tote or carton from storage and sending it to an ergonomic pick station, so operators pick without walking aisles. Addverb's Quadron sequences retrievals so containers arrive in order, which keeps stations busy and order release predictable. This suits e-commerce, retail, fashion and spare-parts operations with many SKUs and small order lines. -
Should I choose single-deep or double-deep carton shuttle storage?
Choose single-deep carton shuttle storage when every SKU needs instant access and very high throughput, and double-deep when storage density matters more, since it holds two containers per location. Addverb's Quadron supports both configurations. Double-deep storage sometimes needs a front container moved before reaching the one behind it, so slow-moving SKUs usually go to the rear positions.
