Vertical Lift Modules (VLMs) in Phoenix & Statewide Arizona
Compact, high-density, goods-to-person storage—designed, installed, and supported locally by Storage Equipment Systems.
If you’re running out of floor space or dealing with slow, error-prone picking, a Vertical Lift Module (VLM) turns ceiling height into storage capacity. A VLM is an enclosed, tray-based Automated Storage and Retrieval System (AS/RS) that automatically delivers the requested tray to an ergonomic access opening—eliminating walk aisles and ladders, and resulting in far fewer picking errors. Many operations experience dramatic space recovery (often cited at up to 85% compared to shelving) along with faster and safer picking.
What a VLM can do for your Arizona facility
You need more space—but moving into a new facility is costly and disruptive. That’s where mezzanines come in.
- Store vertically to recover floor space. Systems span 11–65 ft, with some models up to 98 ft, based on brand.
- Increase throughput with goods-to-person delivery, handling up to around 120 trays/hour, depending on setup.
- Select trays up to 161" wide, with payloads from 725 kg to 1,000 kg, based on model.
- Improve inventory control using barcodes or RFID, software-directed picks, and audit trails.
- Enhance ergonomics and safety by reducing steps, bending, and climbing.
VLMs vs. Vertical Carousels
Understanding the key differences to select the optimal solution for your needs.
Vertical Lift Modules
VLMs use a central inserter/extractor mechanism to retrieve trays and deliver them to the operator, optimizing storage based on item height.
- Central inserter/extractor mechanism
- Dynamic tray height optimization
- Higher weight capacity (up to 1,000 kg)
- Superior space utilization
- Higher throughput capabilities
Vertical Carousels
Vertical carousels rotate carriers in a continuous loop to deliver items to the operator, offering a simpler mechanical design.
- Rotating carrier system
- Fixed carrier heights
- Lower weight capacity per carrier
- Simpler mechanical design
- Often lower initial investment
Both systems offer significant advantages over traditional shelving. We'll help you choose based on your specific item mix, storage heights, throughput targets, and budget considerations.​
Specs & options we configure
You need more space—but moving into a new facility is costly and disruptive. That’s where mezzanines come in.
- Heights (roughly 11–65 ft typical; select systems ~98 ft) and tray sizes up to ~161" width.Tray payloads from ~725 kg to ~1,000 kg depending on brand/series.
- Single, dual, or multi-bay access; pass-through to mezzanines; hoists/conveyors for kitting lines.
- Controls & software with pick-to-light, batching, and WMS/ERP integration.
- Security (locks, operator permissions) and safety (light curtains, interlocks).

Integration-ready
(brand-agnostic)
We design, install, and service VLMs from leading OEMs—including Kardex (Shuttle XP), Modula (Lift), and Hänel (Lean-Lift)—so your system fits your items, not the other way around.
For context, OEM literature commonly lists tray widths up to ~4,100 mm/161 in and payloads up to ~990–1,000 kg per tray, with throughput up to ~120 trays/hour depending on configuration. We’ll translate those ranges into a right-sized, test-fit design for your SKUs and pick profiles.
