Maximize Your Floor Space: Comparing Horizontal Carousels, Vertical Carousels, and VLMs
Boosting warehouse efficiency often starts with choosing the right Automated Storage and Retrieval System (AS/RS). While Horizontal Carousels are excellent for high-speed picking, many businesses find that Vertical Carousels or Vertical Lift Modules (VLMs) are better suited for their specific footprint.
But how do you choose? Let’s break down the technical differences to help you find the most cost-effective solution for your facility.
Vertical Lift Module (VLM): The Ultimate in Adaptability
A Vertical Lift Module (VLM) is an enclosed automated storage system designed to maximize height within a compact footprint.
- Dynamic Storage: VLMs automatically measure the height of every tray. With adjustable shelf heights up to 28 inches, the system optimizes internal gaps to eliminate “air storage.”
- Scalability: The module’s total height can be tailored to your specific warehouse ceiling, reclaiming up to 90% of wasted floor space.
- Best For: Businesses with diverse product sizes and those looking to significantly reduce worker travel time.
Vertical Carousel: Precision and Environmental Control
Unlike their horizontal counterparts, Vertical Carousels operate on a vertical loop, much like a Ferris wheel.
- High Throughput: By integrating multiple units, you can achieve rapid picking speeds in a very small area.
- Climate Protection: These units are ideal for sensitive inventory, as they allow for easy temperature and humidity control.
- Important Note: Vertical Carousels require relatively even weight distribution across the carriers to ensure smooth mechanical operation.
Maintenance, Safety, and Compliance
To keep your warehouse automation running at peak performance, regular servicing is a legal and operational necessity. Much like forklifts or overhead cranes, carousels and VLMs require:
- Periodic Maintenance: To prevent costly downtime.
- Certification Compliance: Ensuring your equipment meets all UK safety standards and LOLER regulations.
