Automated Vertical Lift Module (VLM) Pallet Storage System - Top China Suppliers & Factory Solutions
What are the advantages of choosing an intelligent Vertical Lift Module?
Flexible, Efficient, and Cost Effective
The Vertical Lift Module system empowers warehousing and material handling with cutting edge technology – saving time, space, and costs, while making your workflows smoother and more efficient.
Space Saving / Maximize Height Utilization
Maximize vertical space utilization to achieve the greatest storage capacity within the smallest footprint, effectively reducing costs and enabling more economical use of storage areas.
Ergonomic & Safe
The ergonomic design minimizes physical strain on workers. Unlike in conventional warehouses, operators no longer need to walk long distances, climb shelves, or use ladders and pulleys – effectively reducing operational hazards.
Reduces Labor Costs
It automatically delivers required materials to the access point at high speed and stops at an ergonomically optimal height. This "goods to person" design significantly shortens access time and reduces worker fatigue.
Optimized Material Management
The management software can run independently for inventory control or seamlessly integrate with your existing ERP, MES, SAP, and other data processing systems, ensuring real time and accurate synchronization of inventory information.
Features of Intelligent Vertical Lift Module (VLM)
Modular structural design allows for easy height adjustment, enabling rapid delivery and deployment.
Dynamic storage location allocation technology – pallet height is measured dynamically during the loading process, enabling real-time compaction to achieve optimal storage density.
Access point with automatic doors enhances safety for both operators and stored goods, while reducing noise. The sealed enclosure provides better protection for the items.
A single unit can accommodate pallets with different load capacities, lowering procurement costs and ensuring flexible, continuous operation.
Current-based weighing method or load cells are used to monitor the weight of pallets and the shuttle, preventing overload of individual pallets or the entire system.
Chain drive system delivers high load-bearing capacity with an anti-skew design, ensuring stable and efficient storage/retrieval operations and a long service life.
How does the Vertical Lift Storage System work?
Main Frame Structure of the Vertical Lift Module
The main body of this equipment is fabricated from national standard cold-rolled steel. The frame consists of eight load bearing columns, horizontal connecting beams on both sides, and diagonal bracing struts. The columns serve as the primary load carrying members, supporting the entire load. Inside the cabinet, modular pallets are arranged in a matrix and placed on the bracket slots on the front and rear sides. The overall height can reach up to 20 meters, and it can span multiple floors, with independent access points for loading and unloading materials on each floor.
Schematic Side View of the Storage System Structure
It is mainly divided into three major areas: the back storage area, the central operating area, and the front storage area. The pallet matrix-type combination structure is placed in both the front and rear storage areas. Where conditions permit, it is extended as high as possible to make full use of the three-dimensional space and improve floor space utilization.
How to choose the pallet size?
The selection can be determined based on a comprehensive consideration of the weight, volume, and quantity of the materials to be stored, as well as the dimensions of your containers. The general principle is to choose the largest possible pallet size that your site conditions allow, so as to achieve the maximum return on the minimum investment. Alternatively, you can provide us with your specific requirements, and we will help evaluate the most suitable solution for you.
Customization Services
The equipment can be raised, lowered, or relocated. It can span multiple floors, and can be configured with up to five access points at the front and rear, facilitating simultaneous operations across different floors. To increase warehouse capacity, if installation outside the building is permitted, an additional external structure can be added. In this case, stored goods can be accessed through specially designed openings in the wall.
Integration with Other Systems/Equipment
To accelerate material sorting and storage/retrieval efficiency, conveyor belt technology can be used to connect workstations, while also reducing the intensity of manual handling.
The equipment can interface with robots and other automated handling devices to meet production line requirements and achieve automated storage.
In "goods-to-person" picking scenarios, the WCS (Warehouse Control System) receives picking instructions from the WMS (Warehouse Management System) and dispatches AGVs to enable automatic transfer of goods between storage locations and workstations.
Manually operated to perform gripping, transferring, and placing tasks. It is suitable for heavy-load warehousing and manufacturing workshops, assisting operators in handling large workpieces, molds, and heavy materials.

Frequently Asked Questions (FAQ)
A1: The VLM system maximizes vertical warehouse space, reduces footprints, lowers labor costs, enhances worker ergonomics and safety by eliminating climbing, and optimizes inventory control through integration with ERP/WMS systems.
A2: The VLM uses dynamic storage location allocation technology. During the loading process, the height of each pallet is measured dynamically, allowing the system to compact storage locations in real-time based on the actual height of the stored items.
A3: Yes. The system can reach up to 32 meters in height and span multiple floors. It supports configurations with up to five access points (picking windows) at the front and rear, allowing simultaneous loading and unloading across different levels.
A4: The VLM can seamlessly integrate with conveyor lines, robotic arms/manipulators, AGVs (Automated Guided Vehicles) via WCS/WMS dispatch, and manually operated jib cranes to achieve automated, high-efficiency material handling.
A5: It utilizes current-based weighing methods or built-in load cells to continuously monitor the weight of individual pallets and the shuttle. This prevents overload of single components as well as the entire system, ensuring stable, long-term operation.
A6: Standard pallet widths range from 850 mm to 4100 mm, with five standard depths (450 to 1120 mm) and five standard heights (50 to 133 mm). Load capacities are divided into five levels ranging from 100 kg up to 1000 kg per pallet.
