Vertical Lift Modules Explained: Maximize Efficiency with VLMs

Vertical Lift Modules Explained: Maximize Efficiency with VLMs

May 30th 2025

As warehouse demands evolve and space becomes more valuable than ever, automation is no longer optional; it's a competitive necessity. Vertical Lift Modules (VLMs) are at the forefront of that transformation.

At Warehouse1, we help operations teams across industries reclaim space, reduce labor costs, and boost productivity through expert integration of VLM systems.

What is a Vertical Lift Module (VLM)?

A Vertical Lift Module is an enclosed automated storage system that uses trays, delivered via a computer-controlled extractor, to bring stored items directly to the operator at an ergonomic height. Think of it as a high-rise building for your inventory, with a brain that knows exactly where everything is.

Types of VLMs

Tray-Based Systems

The most versatile, it is ideal for warehouses handling a wide range of item sizes. The system auto-detects item height and adjusts storage accordingly.

Shelf-Based Systems

Designed for facilities with high volumes of similar-sized SKUs. Less flexible, but excellent for repetitive storage needs.
