What are Vertical Lift Modules (VLMs)?

Vertical Lift Modules, commonly referred to as VLMs, are automated storage and retrieval systems designed to optimize the utilization of vertical space in warehouses. These systems consist of two tall columns with trays or shelves in between. A computer-controlled mechanism operates the VLM, retrieving and storing items from the trays based on real-time demand. By maximizing vertical space, VLMs minimize the need for excessive floor space, making them a valuable asset in modern warehousing.

Improved Space Utilization

One of the primary advantages of VLMs is their ability to significantly enhance space utilization within a warehouse. Traditional storage systems, such as static shelving or pallet racks, often leave unused vertical space. However, VLMs capitalize on this otherwise wasted space by vertically storing goods. This leads to a more organized and efficient warehouse layout, allowing businesses to store a higher volume of inventory in a smaller footprint.

Enhanced Order Picking Efficiency

In an increasingly competitive market, order picking efficiency plays a critical role in meeting customer demands and expectations. VLMs offer a streamlined order picking process, reducing the time and effort required to locate and retrieve items. With an automated system that brings the requested items to the operator at an ergonomic height, order fulfillment becomes faster, more accurate, and less physically taxing for warehouse personnel.

Increased Productivity and Throughput

VLMs significantly contribute to increased productivity and throughput in warehousing operations. The automated retrieval process ensures that workers spend less time searching for items, leading to a higher number of picks per hour. This boost in productivity results in faster order processing and ultimately greater customer satisfaction. Moreover, with VLMs handling the heavy lifting, employees can focus on value-added tasks, such as quality control and order verification.

Enhanced Inventory Management

Accurate and efficient inventory management is vital for any successful warehouse. VLMs are equipped with integrated inventory management software that keeps real-time track of inventory levels. The automated system updates inventory counts after each retrieval or storage action, reducing the risk of stockouts or overstock situations. This advanced inventory control helps businesses maintain optimal stock levels, leading to reduced carrying costs and better overall inventory accuracy.

Improved Safety and Ergonomics

Warehouse work can be physically demanding, and safety is of utmost importance. VLMs contribute to a safer working environment by reducing the need for manual material handling and ladder climbing. Workers can access items at a comfortable waist-high level, minimizing the risk of accidents and injuries associated with traditional shelving systems. By promoting better ergonomics, VLMs can lead to a decrease in worker fatigue and absenteeism, further enhancing overall warehouse efficiency.

Space Savings for Future Growth

As businesses grow and expand their operations, warehouse space becomes a valuable commodity. VLMs not only optimize existing space but also create opportunities for future growth. By efficiently using vertical space, businesses can delay the need for costly expansions or moving to larger facilities. This cost-saving measure allows organizations to invest in other critical areas of their business while still meeting the increasing demands of their customers.

Increased Accuracy and Error Reduction

Human errors in order picking and inventory management can lead to costly mistakes and dissatisfied customers. VLMs offer a high degree of accuracy by precisely delivering the requested items to the operator. With barcode scanning and integrated warehouse management systems, the likelihood of errors is minimized. As a result, businesses can maintain a reputation for reliable and error-free order fulfillment, fostering customer trust and loyalty.

Environmental Sustainability

Sustainable practices are becoming increasingly important to both consumers and businesses. VLMs contribute to environmental sustainability in several ways. Firstly, their space-saving design reduces the need for additional construction and, consequently, the consumption of building materials. Secondly, the efficient order picking process leads to fewer energy expenditures, as less time and energy are required to locate and retrieve items. Embracing eco-friendly solutions like VLMs can help companies attract environmentally conscious customers and contribute to a greener future.


In conclusion, Vertical Lift Modules (VLM) offer a myriad of advantages that significantly impact the efficiency of warehousing operations. From improved space utilization and enhanced order picking efficiency to increased productivity and inventory management accuracy, VLMs are a game-changer in the logistics industry. Furthermore, these systems prioritize safety and ergonomics, ensuring a more pleasant work environment for employees.

By embracing VLM technology, businesses can streamline their operations, reduce costs, and position themselves as industry leaders focused on sustainability and customer satisfaction.
