Features & How it Works
The Compact Double VLM uses a dual-tray extractor system that delivers one tray to the operator while simultaneously retrieving the next—eliminating downtime between picks. Trays are stored vertically and automatically spaced using smart height sensing to maximize density. When an operator requests an item, the system’s rack-and-pinion elevator moves quickly and smoothly to retrieve the correct tray and present it at an ergonomic access window.
Key features include:
-
Dual-Tray Delivery – Keeps picking fast by staging one tray while the other is in use.
-
Rack & Pinion Drive – Ensures smooth, precise motion and long-term reliability.
-
Smart Height Detection – Automatically adjusts tray spacing to optimize storage.
-
Ergonomic Access Point – Trays arrive at a safe, comfortable working height.
-
Safety Light Curtain – Immediately halts movement if anything crosses the access window.
-
Customizable Tray Layouts – Flexible compartments keep inventory organized and accessible.
-
WMS Connectivity – Seamlessly integrates with software for inventory tracking and control.
This system transforms your storage into a compact, high-speed, operator-friendly solution that adapts to your workflow.
