What is the difference between a Vertical Lift Module (VLM) and a vertical carousel?

The key difference between a Vertical Lift Module (VLM) and a vertical carousel lies in storage efficiency, automation intelligence, and ergonomics.

Comparison overview:

Feature Vertical Lift Module (VLM) Vertical Carousel
Storage method Trays dynamically stored by height Fixed rotating shelves
Space efficiency Very high (dynamic slotting) Moderate
Ergonomics Goods delivered at waist height Operator waits for rotation
Speed & accuracy Faster, software-optimized Slower, mechanical rotation
Inventory control Advanced WMS integration Limited software control

Why modern facilities choose VLMs?

VLMs automatically adapt to changing inventory profiles, making them ideal for manufacturing, aerospace, medical, electronics, and MRO operations.
