What Are Vertical Lift Modules and How Do They Work?

If you’ve ever worked in a warehouse, you know how hard it is to deal with disorganized shelves, lost inventory, or not enough space. That’s where vertical lift modules (VLMs) come in. 

They help you organize and store your items efficiently while minimizing the use of space. Today, we will be exploring more about them and how they work. Stay tuned. 

What is a Vertical Lift Module (VLM)? 

Imagine a vertical cabinet with shelves that move up and down to deliver the item you want directly to you. That’s a VLM. It’s a computer-controlled storage system designed to save space, improve organization, and productivity, and make it easier (and faster) to access items. VLMs follow the Goods to Person principle, delivering goods directly to workers. 

A vertical lift module has two main parts. It has storage columns and an extractor platform. Storage columns hold trays with the items you’re storing, and the extractor platform is the part that moves vertically to retrieve or place trays into the system. The VLM will automatically organize storage trays based on the software’s logic.

VLMs are enclosed with trays that are laid on top of each other in the front and the back of the module. Then the extractor platform (that works like an elevator) takes the tray you need and brings it to you.

They can go up to 50 feet, and manufacturers often use lasers to figure out what the maximum height for the module is. They have different weight capacities (depending on the type of VLM and manufacturer) that can go up to 2,000 pounds per tray, but what you need, of course, depends on what you plan on using the vertical lift module for.

The idea is quite simple. Instead of you climbing ladders or walking around searching for things, the machine brings the items to you. It is very convenient, and since these machines are vertical, they are a great way to use space effectively.

How Do VLMs Work? 

So, let’s take a look at how VLMs work: 

Putting the Items In 

First, you load the items you want to store onto trays inside the VLM. These trays are customizable, so you can usually find a tray setup that works for you.

The VLM’s software tracks where each tray is located and organizes them in a way that makes sense for easy retrieval. 

Retrieval Request 

When you need an item, you enter a request. You usually do this by typing in the item name or scanning a code. 

The Item Is Brought to You 

The extractor platform springs into action. It zips up or down to find the exact tray you need. Once it grabs the tray, it delivers it to an access opening (usually at waist level) so you don’t have to bend or stretch. This also improves safety, and productivity, and helps workers not lose too much time looking for items. 

Return and Repeat 

When you’re done with the item, you can place it back on the tray, and the system will store it away again. The whole process is fast, efficient, and keeps everything super organized. 

What Makes VLMs So Special? 

Here’s why so many businesses love VLMs: 

Space-Saving Design 

VLMs go up into space (they’re vertical), so the design is really well thought out and helps you save a lot of space. They can save up to 90% of floor space compared to traditional methods. This is especially helpful if you’re working in a small facility or want to make room for more inventory. 

Speed and Efficiency 

VLMs bring the item directly to the operator, which speeds up the picking process. This is a huge win for warehouses handling a lot of orders. 

Better Organization 

Everything in a VLM is tracked digitally. You know exactly where each item is stored, which reduces errors and makes inventory management a simpler and easier process. 

Improved Safety 

Climbing ladders, lifting heavy boxes, or even bending can lead to serious injuries. With VLMs, you don’t have to do any of that. Items are delivered at a comfortable height, making the work safer and less physically demanding. 

Security 

Since VLMs are computer-controlled, they can restrict access to certain items. This is great for businesses storing high-value or sensitive materials. Only authorized personnel can retrieve specific trays, adding a layer of security. Also, all of the operations are monitored, which helps you keep track of things. 

Reduced Labor Costs 

Vertical lift modules can reduce labor costs by making storage and retrieval faster and easier. Instead of workers walking around to find items, the VLM brings the items directly to them, saving time. This means fewer workers are needed to handle the same amount of tasks. Plus, the system reduces errors, so less time and money are spent fixing mistakes. It’s an efficient way to do more with fewer people. 

They Have Fast ROI (Return On Investment) 

VLMs often have a fast ROI since they help you enhance your operations and save money. They save space, reduce labor costs, help reduce mistakes, and improve efficiency, which can help you earn back your initial investment quickly. 

They Can Be Integrated With Other Automation Systems 

Another benefit of these modules is that they can be integrated with other automation systems. They work well with warehouse management systems (WMS), robots, or conveyor belts. For example, a robot can retrieve items from a VLM and deliver them to a packing station. This can boost speed, accuracy, and overall efficiency. 

Where Are VLMs Used? 

You’ll find VLMs in all sorts of industries. They can be helpful in industries that need to store a lot of stuff and retrieve it efficiently. Here are some examples:

• Warehouses and distribution centers: VLMs can be very helpful in warehouses and distribution centers because they help store and retrieve products quickly and efficiently. 
• Manufacturing facilities: They can be helpful for organizing tools, parts, and raw materials. 
• Pharmacies and hospitals: To store medical supplies and pharmaceuticals in a clean, controlled, and safe environment. 
• Retail: For managing inventory in back rooms or fulfillment centers. 

Should You Invest in a VLM? 

If your business involves managing a large inventory or you’re constantly running out of space, a VLM might be worth considering. They can help you enhance your operations, save space, and make your workplace a safer space for everyone. However, it’s important to weigh the costs and consider whether the system fits your specific needs. 

Final Thoughts 

So, that was it for today’s article. Overall, VLMs can help you enhance efficiency, organization, security, and safety in the workplace. Investing in them can be a great solution for your business, especially if you handle a lot of inventory and have limited storage space.

If you have made up your mind and are considering this option, Modula VLMs are one of the best and are very high in demand right now, so it’s definitely worth checking them out.
