Vertical Lift Module Maintenance: How to Keep Your VLM Running at Peak Performance

Written by Kate Moore | 1/13/26 3:56 PM

Vertical lift modules (VLMs) are a significant investment. Keeping them running smoothly takes more than smart design. It takes smart maintenance. 

 

Like any high-performance equipment in your warehouse, VLMs need regular attention to perform at their best. Vertical lift module maintenance isn't just about preventing breakdowns. It's also about maximizing uptime, maintaining accuracy, and protecting your bottom line. 

 

For this article, we interviewed Nathan St. Pierre, Director of Service at Kardex, to understand more about what's involved with VLM maintenance.

 

With 22 years of maintenance experience, Nathan brings a wealth of industry knowledge about how to get the most ROI from your machine through proper maintenance. 

 

“Our goal is to keep every Kardex system performing like the day it was installed,” says St. Pierre. “That consistency is what our customers rely on.” 

 

What sets Kardex apart is its partnership with its customers, ensuring their investment reaps benefits for years after purchase with regularly scheduled upkeep and support.  

 

In this article, we’ll detail what vertical lift module maintenance entails and how to set your system up for decades of reliable performance.

Vertical Lift Module Maintenance Schedule 

 

If you’re considering buying a vertical lift module, you are probably wondering about how often it requires regular maintenance. We have great news. When you purchase from Kardex, your role in VLM maintenance is minimal.  

 

Your local Kardex service team keeps track of your service history and schedules visits with you. You don't need to remember when service is due. It's all managed for you. 

 

But how often will your VLM need maintenance? The answer is: it depends.

 

Your usage intensity does affect your maintenance needs. For light-duty, single-shift operations, bi-annual visits may be all you need.  

 

If you're running three shifts or operating around the clock, Kardex typically suggests a 24/7 after-hours support contract.  

 

Many high-intensity operations also purchase a spare parts package to keep on-site, which significantly reduces downtime when a quick fix is needed. 

 

A key advantage of the Kardex Shuttle design is that when maintenance is up to date and the machine is used within specification, there are few wear items. The components that do require regular inspection include tray shoes and door glides, far fewer than you'd see with traditional storage systems. 

 

"Provided maintenance is up to date and the machine is used within specification, wear parts are minimal," notes St. Pierre "That's one of the big advantages of our design." 

 

 

How to Maintain Your Vertical Lift Module 

 

Keeping your vertical lift module running well means taking a proactive approach. It helps you catch potential issues during scheduled maintenance rather than discovering them when a system stops working during your busiest shift.

 

Our service visits are designed with your specific operations in mind, whether you run around the clock, or have unique operational requirements.

"Every visit is about prevention," explains St. Pierre. "We're looking for the small signs of wear before they turn into downtime." 

 

During a typical VLM service visit, a Kardex Lifecycle Services technician performs a comprehensive check that includes: 

 

  • Visual and operational inspection of the machine. 
  • Belt and chain tension checks with adjustments as needed. 
  • Offsets and adjustments if needed. 
  • Control drawer inspection for voltage and loose connections. 
  • Complete documentation with a digital service report. 

 

 

Why Kardex Shuttle Vertical Lift Modules are Easy to Maintain 

 

Not all VLMs are created equal when it comes to serviceability.

 

The Kardex Shuttle VLM features several design elements that make vertical lift module maintenance simpler. 

 

  • Tooth-belt drive system: The belt design makes for cleaner maintenance and straightforward adjustment by design. Unlike chain-driven systems, you won't deal with lubrication mess. Service visits are faster, and your facility stays cleaner. 
  • Fewer moving parts: Less complexity means fewer wear points and less that can go wrong over the system's lifetime. 
  • Smart diagnostics: Control systems and Kardex Connect provide user-friendly diagnostics, helping technicians quickly identify and resolve any issues. 

 

"The belt-driven design isn't just quieter, it's cleaner and easier to maintain than a traditional chain," explains St. Pierre. "That means faster service visits and less downtime."

Vertical Lift Module Lifecycle Support 

 

Kardex Life Cycle Services go beyond routine maintenance to provide an ongoing partnership. After each VLM maintenance visit is completed, you'll also receive the service ticket and completed checklist via email, documentation that's critical for facilities with quality certifications or audit requirements. 

 

 

 

Between VLM maintenance visits, integration with Kardex Connect and Kardex Analytics gives you real-time system monitoring, performance data, and predictive maintenance insights. This means if any issues arise, they can be flagged before they cause downtime.  

 

Optional lifecycle support, like spare parts kits, operator training, extended warranty coverage, and system upgrades helps you keep your system running efficiently as your operation evolves. 

 

"Maintenance isn't just about fixing, it's about planning," says St. Pierre. "With tools like Kardex Connect, we can predict issues before they cause downtime." 

 

From maintenance to modernization, Kardex Life Cycle Services can help you reach your operational goals. 

 

 

Maintenance That Protects Your Investment 

 

A well-maintained VLM is an asset that performs like new for decades. With the right maintenance approach, you're not just preventing problems, you're ensuring consistency, safety, and operational efficiency year after year. 

 

"A Kardex system is built to last. Our job is to make sure it stays that way. With the right maintenance, these machines can run efficiently for decades."
