What to Look for in a Vertical Lift Module: Detailed Breakdown
Lift Mechanism
Reliability starts with how your trays move.
Not all VLMs use the same lifting technology. Systems powered by a rack and pinion mechanism offer smooth, direct control with fewer maintenance needs over time. Chain, belt, or cable lifts can wear more quickly and require more frequent upkeep. When downtime isn’t an option, choose a lift system designed for long-term reliability in demanding environments.
Software & Integration
Your storage system should work with your systems.
Advanced VLMs go beyond storage — they become part of your inventory strategy. Choose a system with ERP, WMS, or MES integration, browser-based access, and real-time tracking. Look for features like guided picking, user permissions, and QC/lot tracking to support lean operations and digital traceability.
Storage Density
Get the most storage out of your floor space.
The real value of a VLM is how much inventory it can hold in a small footprint. Features like dual trays per level and compact tray design maximize storage capacity without taking up extra floor space. A dense, efficient layout means you may need fewer machines overall — saving money, maintenance, and real estate.
Service & Support
Reliable support protects your uptime.
Even the best hardware needs maintenance. Ask whether the manufacturer provides U.S.-based technicians, preventative maintenance plans, and fast response times. Avoid being stuck waiting for overseas parts or third-party service. A responsive support team can keep your system running smoothly and catch problems before they become failures.
Ergonomics & Tray Access
Operator comfort improves safety and performance.
Look for a system that brings trays to an ergonomic height, minimizing reaching, bending, and walking. Features like waist-height access, safety curtains, and guided LED picking reduce physical strain, boost accuracy, and help prevent injuries. A better operator experience pays off in efficiency and morale.
Customization & Flexibility
Your storage needs evolve — your VLM should too.
Choose a system that’s built to scale. Whether it’s custom tray sizes, adjustable weight capacity, or reconfigurable tray layouts, the right VLM adapts to your workflow over time. As your product lines grow or change, flexible equipment helps avoid costly rework or reinvestment.
