Vertical Lift Module vs. Vertical Carousel Module: Which Is the Optimal Storage Solution for Your Business?

In the era of Industry 4.0, optimizing storage space, improving warehouse management efficiency, and reducing labor costs have become top priorities for manufacturing and logistics companies. Two of the most prominent automated storage solutions today are the Vertical Lift Module (VLM) and the Vertical Carousel Module (VCM). Both systems offer significant benefits, including:

• High-density storage: Suitable for storing items with low to medium turnover rates. A 6-meter-high unit can provide approximately 5,000 to 7,000 storage locations.
• Automatic goods delivery: Items are automatically delivered to an ergonomically positioned access opening at waist height, improving picking efficiency and operator comfort.
• Restricted access: Fully enclosed systems with controlled access enhance security and inventory protection.
• Space optimization: Maximizes vertical space usage while minimizing floor footprint.

So, between these two technologies, which one best suits your operational needs?

1. Vertical Lift Module (VLM)

A Vertical Lift Module (VLM) is an automated storage system designed like an elevator, consisting of two columns of trays with an extractor in the center. During each operation, the system automatically measures the height of stored items and dynamically assigns trays to the most suitable locations, maximizing space utilization.

Outstanding Advantages of VLM:

• High flexibility: Ideal for storing items of varying sizes and weights
• Exceptional space efficiency: Tray spacing can be optimized down to just 25 mm
• High load capacity: Each tray can handle up to 1,000 kg and can be integrated with lifting aids
• Installation height up to 30 meters, perfect for high-ceiling warehouses
• Dynamic configuration: Easy product changes without manual adjustments or system dismantling

2. Vertical Carousel Module (VCM)

Vertical Carousel Modules (VCMs) consist of a series of carriers fixed to a chain-driven system. Powered by a motor, the carriers rotate vertically in a continuous loop along a guided track, moving both forward and backward to deliver items efficiently.

Key Advantages of VCM:

• Best suited for uniform-sized items: Ideal for components, tools, or spare parts with consistent dimensions
• Cost-effective investment: Simple design results in lower maintenance and operating costs
• Fast picking speed: Can achieve up to 400 picks per hour when properly optimized
• Maximum height of around 10 meters, suitable for warehouses with low to medium ceiling heights

4. Which Should You Choose: VLM or VCM?

• Choose VLM if your business handles a wide variety of products with frequent changes, operates in a high-ceiling warehouse, and requires maximum storage density and picking efficiency.
• Choose VCM if your inventory consists of standardized items with minimal variation and you are looking to optimize initial investment costs.

5. Conclusion

Both VLM and VCM offer substantial advantages in automating warehouse storage and inventory management. However, selecting the most suitable solution depends on several key factors, including warehouse height, product load, item uniformity, and investment budget.
