Vertical Lift Module (VLM)
Automated Storage and Retrieval System
Home / Technology / ASRS
The Vertical Lift Module (VLM), ISD’s automated storage and retrieval system, improves warehouse efficiency, is designed to improve workers productivity, accuracy, and space utilization. This VLM is a core technology for organizations seeking to optimize their storage capacities and improve operational efficiencies. The system utilizes a series of vertically arranged trays in the front and rear of a column, which are then accessed by an automated insert/extractor mechanism in the center. The inserter/extractor delivers the required tray to the ergonomic pick window.

With a small footprint, the VLM can significantly improve storage density by up to 85%, enabling companies to store more in less space. The VLM eliminates wasted worker walk and search time which can save up to 2/3 of an organizations current labor requirement. Likewise, Vertical Lift Modules can be equipped with any level of inventory management ranging from a basic controller to advanced inventory management software. The software can seamlessly integrate into your facility’s WMS (warehouse management systems), WES (warehouse execution systems) and business ERP for real time inventory management and control.
With just a few clicks or barcode scan, operators can easily locate and retrieve inventory, eliminating the time-consuming and error-prone manual searching process. Not only does this boost efficiency, but it also minimizes operational costs associated with misplaced and/or lost products. The vertical lift module automated storage and retrieval system is designed to operate as a single module or integrates with multiple VLMs, software, pick-to-light, flow rack, workstations, conveyors, scanners, and autonomous mobile robots (AMRs) to create a flexible and agile storage and retrieval system.
VLM Key Features and Components
The Vertical Lift Module (VLM) is a sophisticated automated storage and retrieval system that comprises several key features and components to ensure optimal performance and functionality. Let’s explore some of the essential elements that make up a VLM system:
- Vertical Columns: The core of the VLM system is the vertical columns, which house the storage trays. These columns can be customized in height and depth to accommodate the specific storage requirements of the facility.
- Storage Trays: Vertically arranged trays within the columns are designed to hold a wide range of items, from small components to larger products. The trays can be configured with various totes, partitions and dividers, roll out drawers, locked boxes, and custom fixtures based on your inventory’s requirements to optimize storage and retrieval.
- Automated Insert/Extractor Mechanism: At the heart of the VLM system is the automated insert/extractor mechanism, which is responsible for retrieving and delivering the requested trays to the access opening. This mechanism operates with precision and speed, minimizing the time required for storage and retrieval tasks. Every module can be equipped with a single pick window or multiple on one or several floors.
- Control System: The VLM’s control system is the brain of the operation, managing all aspects of the system’s functionality. This includes inventory tracking, tray positioning, and integration with other warehouse management systems.
- User Interface: VLM systems often feature user-friendly interfaces, such as touchscreen displays, control panels, and barcode scanning, allowing operators to easily input commands, monitor system status, and access real-time inventory information.
- Safety Features: VLM systems are designed with robust safety features, such as light curtains, bi-parting rear window doors, emergency stop buttons, and access controls, to protect operators and ensure the secure operation of the system.
By understanding the key features and components of a VLM system, organizations can better evaluate and implement the best solution to meet their specific storage and operational requirements.

How VLMs Work: A Step-by-Step Guide
The Vertical Lift Module (VLM) is a high-density automated storage and retrieval system that streamlines the process of storing and accessing items within a compact vertical footprint. To understand how VLMs work, let’s take a step-by-step look at the process:
- Inventory Placement: The operator or robotic arm places items to be stored into the VLM trays, which are arranged vertically within the system’s column. Trays can be equipped with partitions and dividers, totes, cases, roll out drawers, and special fixtures to accommodate each type of inventory’s unique requirements. Each tray is assigned a specific location or “address” within the VLM. This assignment can be based on smallest height available, closest or furthest to the pick window, random or other custom requirements.
- Storage and Retrieval: When an item needs to be stored or retrieved, the operator or warehouse management system or software sends a command to the VLM’s control unit. The automated insert/extractor mechanism then locates the correct tray and brings it to the access opening, allowing the operator to pick or store inventory accordingly.
- Inventory Management: The VLM’s control system tracks the location and contents of each tray, providing real-time inventory visibility and enabling efficient inventory management. This data can be integrated with a warehouse management system (WMS) or enterprise resource planning (ERP) software for comprehensive inventory control.
- Optimization and Efficiency: The VLM’s vertical configuration allows for a high-density storage solution, maximizing the use of available space within the facility and saving up to 85% of your otherwise wasted floor space. Additionally, the automated retrieval process eliminates the need for manual searching and walking, significantly improving worker productivity and reducing operational costs by up to 2/3.

Industries that Benefit When Implementing a VLM System
Factors to Consider When Implementing a VLM System
When considering the implementation of a Vertical Lift Module (VLM) automated storage and retrieval system, there are several key factors that organizations should carefully evaluate to ensure a successful deployment. Let’s explore some of the critical considerations:
- Serviceability: You will need an organization that can provide 24/7 local service with a phone call. VLMs are incredibly reliable and require scheduled maintenance, but on occasion an operator or the system can have a problem. Knowing that you are one phone call or email away from having a local service team available makes a big difference.
- Facility Layout and Space Constraints: The physical layout of the facility and the available floor space are crucial factors in determining an appropriate VLM configuration. What is your available clear height? Organizations must assess their current and future storage requirements to ensure that the VLM system can be seamlessly integrated into the existing infrastructure.
- Inventory Characteristics: The nature and volume of the items to be stored in the VLM system will influence the design and configuration of the system. Factors such as item size, weight, and velocity must be considered to ensure that the VLM can accommodate the specific storage needs. Every individual tray can be set to operate at an efficient speed based on the inventory’s fragility.
- Operational Requirements: Organizations must carefully consider their operational requirements, including the frequency of storage and retrieval, the need for temperature-controlled environments, and the integration with other warehouse management systems.
- Scalability and Flexibility: As business needs and storage requirements evolve over time, the ability to scale and adapt the VLM system becomes crucial. Organizations should evaluate the system’s scalability, allowing for future expansion or modifications to accommodate growth and changes in the business.
- Integration with Existing Systems: In many cases, the VLM system will need to integrate with the organization’s existing warehouse management system (WMS) or enterprise resource planning (ERP) software. Careful planning and coordination are required to ensure seamless data exchange and real-time inventory visibility across the entire operation.
- Training and Support: Proper training and ongoing support for the VLM system are essential for ensuring optimal performance and maximizing the benefits of the technology. Organizations should consider the availability of training resources, technical support, and maintenance services offered by the VLM manufacturer or supplier.
By carefully considering these factors, organizations can make informed decisions and implement a Vertical Lift Module automated storage and retrieval system that align best with their specific operational requirements and strategic business objectives.
