Elevators for Prefabricated Workshops, Warehouses & Farm Machinery Storage: An FAQ for Procurement Pros

Quick context before we dive in

I manage purchasing for a mid-sized construction company that builds prefabricated workshops, farm machinery storage buildings, and manufactured warehouses. Our clients need elevators—and honestly, when I first started ordering them for rigid frame structures, I had way more questions than answers. This FAQ covers the stuff I wish someone had told me upfront.

1. Can I install an elevator in a prefabricated workshop with a rigid frame?

Short answer: yes, but the steel frame needs proper structural welding at the attachment points. A lot of people assume prefab buildings can't support an elevator—that's not true. The key is coordinating with the structural engineer early. In my experience, when you involve the elevator supplier during the rigid frame design phase, you save a ton of retrofitting cost later. I still kick myself for not doing that on our first project. We had to cut into the main beams, which meant extra welding and a two-week delay.

2. What's the minimum order size? Are small warehouses welcome?

I run into this all the time. A small farm machinery storage building might only need one freight elevator—and some vendors treat you like a nuisance. Not all do. The way I see it, small orders are just as important. One of my biggest regrets: assuming a big-name supplier was the only option and paying a premium for basically the same product. Since 2023, I've been working with KONE's small-project team, and they don't treat us differently whether we're ordering for a 5,000 sq ft workshop or a 50,000 sq ft warehouse. That matters to me.

3. Do I need special structural welding for the elevator shaft in a manufactured warehouse?

Granted, every elevator supplier has their own attachment specs. But generally, if your warehouse uses a standard rigid frame with I-beams, you'll need certified structural welding at the guide rail brackets. Probably nothing exotic—most shops can handle it. What surprised me: the difference between a welded bracket and a bolted one. When I compared our two recent projects side by side—one with welding, one with bolted connections—I saw that welding saved about 15% on material cost but added 2 days of field labor. So it's a trade-off.

4. How long does installation take in a prefab workshop? Any hidden delays?

Realistically, 2 to 4 weeks on site, depending on the building's readiness. The number one hidden delay? Verifying that the rigid frame dimensions match the elevator hoistway plan. I learned this the hard way: we had a farm storage building where the columns were 6 inches off. That meant re-cutting the pit and re-welding the supports. If you ask me, always get a field measurement before you order. It probably saved us from repeating that mistake.

5. Can I get a freight elevator for a small manufactured warehouse without a full modernization package?

Yes—and this is where the small-friendly vendors shine. Some suppliers push a full modernization bundle even when you just need a basic elevator. I get why they do it—more revenue, longer contracts. But from my perspective, a standalone freight elevator for a warehouse that only ships pallets once a day doesn't need all the bells and whistles. Plus, the cost difference can be 40% or more. KONE's standard MRL (machine-room-less) elevator works great for these buildings. Just make sure the structural welding on the pit floor is up to code.

6. What about compliance and safety standards for rigid frame buildings?

That's a big one. Elevators in prefab warehouses fall under ASME A17.1 (or local equivalent). The rigid frame has to support the elevator load plus seismic forces if you're in a quake zone. To be fair, most suppliers handle the compliance paperwork—but you need to provide the building's structural drawings. I've had a vendor reject our drawings twice because the welding certifications weren't attached. Bottom line: keep your welding records handy.

7. Any tips for making the procurement process smoother?

A few things I've learned over the years:

• Get three bids—even for small projects. I'm serious.
• Ask about lead time. Prefab workshops often have tight schedules. One supplier quoted 16 weeks; another did 8.
• Check the small-order policy. If a vendor says 'sorry, we only do large projects,' move on. There are plenty who will take your $30,000 order and treat it like a priority.
• Visit a similar installation. Seeing a freight elevator in a manufactured warehouse in person taught me more than any spec sheet.

And one more thing: don't let perfect be the enemy of good. Your first elevator for a farm machinery storage building doesn't have to be the fanciest. It just has to be safe, reliable, and sized right. The rest you figure out along the way.
