White Systems' Compact Twin Vertical Lift Module
Compact Twin Vertical Lift Modules deliver exceptional performance for high-speed, high-volume operations. VLMs are automated storage systems that use vertical space to organize parts and bring them directly to the operator—eliminating the need to walk, bend, or search through shelves. This makes them ideal for saving space, improving safety, and boosting productivity.
What Sets the Compact Twin Apart
The Compact Twin VLM is engineered for maximum speed and throughput, featuring a dual-tray elevator that enables high-speed picking with the fastest tray retrieval in its class. This high-performance design minimizes wait times, maximizes storage density, making it ideal for environments where every second counts.

Why Choose a Compact Twin?
The Compact Twin is engineered for speed without compromise. With dual tray elevators, it drastically reduces wait times between picks—boosting throughput and efficiency. Ergonomic tray delivery minimizes strain on operators, while smart storage optimization allows more items to be stored in less space.
Optimized for High-Volume Workflows
Whether you’re handling spare parts, tools, raw materials, or finished goods, the Compact Twin is built for operations that demand maximum speed, precision, and organized high-volume storage. Ideal for manufacturing, retail, healthcare, aerospace, and defense, it supports fast-paced environments where every second and every square foot counts.

Dual-Tray Elevator
One tray is presented while the next is being retrieved
Height Optimization
Automatically adjusts for every item’s size
Ergonomic Access
Items delivered at a safe, comfortable height
Compact Footprint
Maximize storage, minimize floor space used
The Compact Twin Vertical Lift Module (VLM) is designed for efficiency, speed, and safety in your storage operations. Featuring a robust metal rack and pinion system, it ensures the quickest tray retrieval, delivering items to a convenient ergonomic height. The VLM is equipped with a safety curtain and additional safety features to protect operators and enhance overall safety.

How the Compact Twin VLM Works
The Compact Twin VLM’s efficient computerized control system ensures precise item retrieval by activating the appropriate trays or shelves and bringing them to the retrieval opening. Once the items are retrieved, the trays return to their original positions, maximizing storage space and keeping items organized.
