Caterpillar dealer Warren CAT has installed a 20-robot AutoStore R5 system comprising 20,852 storage bins inside roughly 5,600 ft² at its Store 05 facility in Midland, Texas, moving parts fulfilment for West Texas and Oklahoma onto a goods-to-person platform.

The integrator, Kardex, fitted the cube with three CarouselPorts and two ConveyorPorts and overlaid its FulfillX warehouse execution system on Warren CAT's existing FDC WMSv2. The WES sequences outbound work by category, due date and urgency before releasing tasks to the robots, a design intended to keep Will Call, Parts Shuttle and Engine Shop orders on differentiated service levels without manual triage.

What did the design phase actually quantify?

Kardex analysed more than 93,000 historical orders, close to 300,000 order lines and nearly 25,000 unique products before sizing the build. The resulting configuration targets 3,648 picking lines and 751 put-away lines per day at anticipated fifth-year volumes, giving the dealer a defined throughput envelope rather than an open-ended automation promise.

Early operating data points to the expected gains. Operator travel has fallen and small-parts storage density has risen since go-live, according to Kardex, with both metrics anchored to the AutoStore footprint rather than to the wider 5,600 ft² envelope.

Who is carrying the commercial risk?

Warren CAT owns the integration risk on the dealer side: Store 05 bundles a storefront, engine shop, warehouse and parts distribution operation, meaning downtime or mis-sequenced orders cut across retail and service revenue streams simultaneously. Kardex carries the design risk, having committed capacity to a specific fifth-year pick count rather than a generic unit count.

Fred Fox, president of Kardex Solutions, said: "Warren CAT now has a parts fulfilment platform that is delivering practical value today while giving the operation room to grow."

How does the system scale from here?

The AutoStore architecture permits incremental expansion through additional robots and ports, which matters for a dealer whose equipment population across West Texas and Oklahoma can swing with oilfield, construction and power-generation cycles. Adding capacity inside the existing cube footprint avoids the lead time of a second facility and keeps the WMS-WES integration intact.

What does this signal for industrial parts automation?

Heavy-equipment dealers have lagged big-box retailers and 3PLs on goods-to-person adoption, partly because their SKU profiles skew toward bulky, high-value components that resist bin storage. The Warren CAT build suggests the threshold is shifting: Kardex carved out a defined small-parts population of roughly 25,000 SKUs and routed the rest of the operation around it, leaving traditional shelving and counter picks for items the cube cannot absorb.

For shippers and carriers, the operational signal is indirect but relevant. A denser, software-orchestrated parts hub compresses the time between order receipt and carrier hand-off, tightening pickup windows at the warehouse dock and shifting more of the daily order release into predictable, batched waves rather than ad-hoc will-call traffic.

The next test for the Midland site is whether fifth-year volumes actually arrive at the 3,648-pick design point. Kardex's expansion path, additional robots and ports inside the same footprint, gives Warren CAT a way to bridge any shortfall without re-engineering the underlying WES-to-WMS handshake.
