See It In Action

See how a vertical lift module works.

Watch the extractor locate a tray, pull it from the column, and present it at the access window in seconds. It is the clearest look at how a VLM turns a walk through shelving into a single ergonomic pick.

Smart, space-saving storage that adapts to your inventory profile.

A vertical lift module (VLM) is an enclosed automated storage and retrieval system built from two columns of trays with a central extractor running between them. Call for a part and the extractor pulls that tray and delivers it to an ergonomic access window at waist height: goods to person, not person to goods. Unlike a vertical carousel, a VLM measures every tray as it is stored and assigns locations dynamically by item height, which is how it holds the same inventory in as little as one tenth of the floor space static shelving needs.

VLMs suit variable-height inventory, spare parts, tools, and high-value or controlled materials. Aerospace, electronics, MRO, medical, and manufacturing operations rely on them wherever floor space is expensive and every pick has to be exact. Inventory software, laser pointers, and LED position bars direct each pick to the right tray location, so accuracy holds steady across shifts, new hires, and seasonal peaks.

How We Help

See how VLMs deliver scalable, space-efficient automation.

With height-optimized storage, flexible configuration, and high-speed picking, VLMs enable higher productivity in less space.

  • Maximizes Vertical Space

    Dynamically adjusts tray positions based on item height, storing more inventory in the same footprint than static shelving or traditional carousel systems.

  • Increases Picking Speed

    Trays are delivered directly to the operator. Add pick-to-light for guided retrieval and improved accuracy, especially in multi-line or high-mix orders.

  • Boosts Efficiency

    VLMs excel in operations with fluctuating part sizes and order profiles, making them ideal for MRO, aerospace, and custom production workflows.

  • Supports Inventory Security

    User authentication and access controls help protect sensitive inventory, with audit trails for full traceability.

  • Easy Expansion

    Modular architecture lets you add units as needed, scaling up storage capacity without major construction or system changes.
