Comparing Modula Vertical Lift Modules: Lift, Slim, Next & FlexiBox

When it comes to improving space utilization in warehouses, distribution centers, and manufacturing facilities, Modula’s Vertical Lift Modules (VLMs) offer innovative automated storage solutions tailored to various operational needs. Choosing the right Modula VLM model can significantly impact workflow, space utilization, and picking productivity.

In this blog post, we’ll compare four popular Modula Vertical Lift Modules, including Modula Lift, Modula Slim, Modula Next, and Modula FlexiBox, highlighting their unique features, ideal applications, and benefits.

What is a Modula Vertical Lift Module?

Before diving into the models, a quick refresher: A Modula Vertical Lift Module (VLM) is an automated storage system that uses trays stored vertically inside a compact footprint. This solution delivers trays to the operator at an ergonomic working height, reducing picking times, improving inventory accuracy, and saving up to 90% floor capacity.

Key Benefits (All Modula VLM Models):

• Space Optimization – Modula VLMs maximize vertical storage, reclaiming up to 90% of floor space compared to traditional shelving.
• Variable Pitch (Tray Height) – In addition to being highly customizable, Modula VLMs have adjustable tray heights (variable pitch), allowing trays to be configured for different product sizes to maximize storage density unlike traditional vertical carousels with fixed shelf heights.
• WMS/ERP Integration – All models are designed for seamless integration with WMS and ERP systems, enabling real-time inventory management and tracking.
• Secure, Enclosed Storage – Modula VLMs provide secure, enclosed storage, protecting inventory from unauthorized access and environmental factors.
• Enhanced Productivity/Ergonomics – All models are engineered to improve picking speed, reduce errors, and provide ergonomic access to inventory, enhancing worker safety and efficiency.
