A Vertical Lift Module (VLM) is a vertical automated storage and retrieval system (AS/RS). It is comprised of trays in the front and back and an inserter/extractor system that runs down the center. Trays are automatically retrieved and delivered to a pick window for picking. When complete the inserter/extractor will retrieve and store the tray in either the designated position or will automatically assign a position based on using the least amount of space or fastest/slowest accessibility (all user defined). It’s modular design and construction make it easy to modify and change heights, locations and pick windows at any time.
VLMs are an ideal for maximizing vertical cube up to 85% while providing access to hundreds and thousands of SKUs. Trays can be used for cases, totes and large items or utilized with partitions and dividers to create a tremendous number of SKU position or cells on one tray. Integrated pick-to-light, augmented vision and laser pointers can be used to assure 99.99+% accuracy and throughput.
VLMs are equipped with basic internal controls and inventory handling management system. Trays can be stored based on utilization, size, weight or another custom parameter you might have. The system can also be told to cube or maximize its density to find additional storage space. In this case every tray is automatically measured and then stored to create more storage capacity… automatically.
Likewise, every VLM or group of VLMs can be easily integrated into WMS and WES software systems for maximum optimization.

Why Work With Conveyco
Conveyco provides decades of experience and RightFIT™ systems methodology to an application and facility solution. By diving into the data and business requirements (see RightFIT methodology) Conveyco does not look at a situation and figure out how to make a technology work, but the opposite. Conveyco looks for the best solution regardless of the technology and/or process(es). Many times, the best solution is a blend of improved processes and multiple integrated technologies… this is what separates Conveyco solutions from a materials handling dealer.
