Vertical Lift Module for Utah Aerospace and Defense Suppliers

Northern Utah has one of the densest aerospace and defense supply chains in the Mountain West. Hill Air Force Base and its depot maintenance work anchor Davis and Weber counties; composite structures, propulsion, avionics and precision machining suppliers line I-15 from Ogden and Clearfield down through Salt Lake City, West Valley and into Utah County. Most of them share the same stockroom problem: thousands of small, expensive, lot-controlled items that must be found fast, kept clean and handed out only to the people authorized to touch them.

The Vidir Lift Module (VLM) is the machine Material Handling USA supplies for that problem. Trays live in two enclosed towers; a center elevator brings the requested tray to a waist-height opening, the operator picks or stocks, and the tray goes back. This page is written for the Utah buyers we talk to most often:

• Tier 1 to tier 3 suppliers and machine shops storing kitted hardware, fixtures and finished parts awaiting inspection or shipment.
• MRO and depot-level maintenance operations issuing rotables, consumables and calibrated tooling from a controlled crib.
• Avionics and electronics assembly cells that want components stored by lot in a single, enclosed system.
• Composite and propulsion plants holding tooling inserts, fasteners and small sub-assemblies close to the line.

A VLM is two tray towers, one in front and one in back, with an elevator running up the middle. Trays are steel, one piece, 96.5 inches wide by 32.5 inches deep, and hold items up to 30 inches tall. When an operator loads a tray at the access opening and confirms the store command on the 12-inch touchscreen, the tray is pulled onto the elevator and passes a set of height sensors. The controller measures the tallest item on the tray, calculates the tightest free slot in either tower, and slides the tray into it.

That is the important difference from a shelf or a carousel: tray spacing is variable. Vidir’s triple tray supports and multi-positional rails allow storage heights in roughly 1.2-inch increments, so a tray of flat brackets takes a thin slot and a tray of fixtures takes a tall one. Nothing is reserved for air. Retrieval runs the same way in reverse: call the tray by part number or tray ID, and it arrives at the opening at an ergonomic height.

Aerospace and defense stockrooms are judged on traceability as much as on space. Vidir’s standard controller runs pick and stock lists, tracks tray contents and prints reports from any connected PC; the Full Inventory Control System (VIP) extends that to part-level tracing, and Vidir publishes ERP integration so the machine can take orders from your own system. A badge reader option ties every transaction to a logged-in user, and a bar code scanner option confirms the part being picked or stored. Pic-to-Lite, a horizontal LED strip across the opening, points to the tray position holding the item.

Trays themselves can be fitted with dividers, partitions and containers sized to the parts, so a tray of fasteners, a tray of foam-nested cutting tools and a tray of machined brackets each get a layout that prevents mixing. Every tray capacity is monitored in the software, so an overloaded tray is refused rather than stored.

Two access options matter to Utah shops with a crib window. The Tray Transporter lets a tray be pulled out of the machine and wheeled to a work cell, with the software noting the tray is out so tracking is not lost. Fold-out external tray access arms extend the tray in front of the machine for lift-assist loading of heavier fixtures.

A word on compliance. An enclosed, login-controlled storage machine with a transaction log is a strong physical and procedural control. Whether it satisfies a specific contract clause, export-control handling rule, FOD program requirement or quality-system audit is a decision for your quality, security and compliance staff, not for a storage vendor. We supply the machine and the documentation; you map it to your program. Ongoing controls and wear-part support is described on our Vidir parts and service support page, and Vidir’s remote service can diagnose software issues over a connection you authorize.

Both machines bring stored items to the operator and both use the building’s height. The choice usually comes down to how uniform the inventory is. A vertical carousel rotates a fixed set of carriers, so it excels when items are similar in height and the whole inventory turns at a similar rate. A VLM stores each tray at its own height and retrieves any tray directly, so it is the better fit for the wide, uneven inventories typical of aerospace cribs: a few tall fixtures, many trays of flat hardware, and a long tail of slow movers.

Utah plants with wire, cable and hookup spools should also look at the Utah wire spool carousel page; it is a different Vidir machine for a different inventory. The full head-to-head is on our vertical carousel vs. vertical lift module guide, and the generic vertical carousels hub covers the carousel family.
