The Procurement Paradox: Why Splurging on Thyssenkrupp Elevator Parts Saved Us More Than We Spent

Why I stopped buying cheap elevator parts and never looked back

After tracking $180,000 in cumulative spending across 6 years of elevator maintenance, I made a counterintuitive discovery: buying genuine Thyssenkrupp elevator parts was the most cost-effective decision we ever made. Not the cheapest. The most cost-effective.

Let me explain why my spreadsheet broke in favor of the 'expensive' option.

A bet that paid off

In Q2 2024, when our main passenger elevator—a mid-2010s Thyssenkrupp unit—started showing erratic floor-leveling, my maintenance team flagged it. The door operator was acting up. Our usual 'budget' parts supplier quoted $520 for a compatible replacement. Genuine Thyssenkrupp: $890.

I almost went with the $520 option. Almost.

Then I ran the total cost of ownership (TCO). Our procurement policy now requires quotes from 3 vendors minimum because of a $1,200 redo I had to authorize back in 2022. That experience taught me something. Cheap parts failed 3x faster in our high-traffic lobby.

The vendor who sold us the $520 part claimed 'OEM equivalent.' What I mean is they said it would 'match quality.' But did I believe them? Not entirely.

We spent the $890. The payoff: 14 months of zero issues so far. The $520 alternative? Based on history, we'd be shopping for another replacement by month 10.

My 6-year audit of elevator part spending

When I audited our 2023 spending, a pattern emerged. I categorized every replacement part we bought for our four elevators into three buckets: genuine OEM, high-quality aftermarket (like from a specialist supplier we'd vetted), and budget aftermarket.

• Genuine OEM (like thyssenkrupp): Average lifespan 28 months, failure rate 2%. Total cost over 6 years: $42,000. Cost per month of operation: $125.
• High-quality aftermarket (e.g., well-reviewed compatible parts): Average lifespan 20 months, failure rate 8%. Total cost: $34,000. Cost per month: $141.
• Budget aftermarket (the 'bargain' options): Average lifespan 14 months, failure rate like 25%. Total cost: $28,000. Cost per month: $166.

Wait, the 'cheap' parts are cheaper per part but cost us more over time? That's what the numbers say.

I don't have hard data on industry-wide defect rates, but based on our own orders, my sense is quality issues affect about 8-12% of first shipments for budget-tier parts. For genuine Thyssenkrupp parts? Nearly zero.

Where the hidden costs hide

Saved $120 by not buying genuine. Ended up spending $450 on emergency callouts when the cheap part failed at 9 PM on a Friday. That's the pattern.

Let me list the costs most people ignore in their spreadsheet:

1. Emergency service callouts: A non-genuine part failure on a Friday night? That's a $350-500 bill just to get a tech onsite.
2. Downtime cost to tenants: Harder to quantify. But when the lobby elevator is out for 36 hours while we wait for the 'cheap' replacement to arrive, that's a hit to satisfaction.
3. Labor for rework: Same tech, same troubleshooting, same labor cost twice. The genuine part is a one-and-done.
4. Reduced lifespan of other components: An out-of-spec door operator can stress the door panels, rollers, and eventually the motor. It's a cascade.

If I could redo that first cheap controller we bought in 2019, I'd invest in better specifications upfront. But given what I knew then—nothing about the vendor's interpretation of 'compatible'—my choice was reasonable. In hindsight? Expensive.

What thyssenkrupp does right (and where I still go elsewhere)

Thyssenkrupp doesn't try to be a one-stop shop for everything. They focus on what they know: elevator systems, marine engineering, high-grade steel. The vendor who told me 'this isn't our strength—here's who does it better' earned my trust for everything else. When I needed a custom non-structural bracket for a lobby renovation? I didn't call thyssenkrupp. I went to a local metal fabricator. It was faster, cheaper, and exactly what we needed.

I'd rather work with a specialist who knows their limits than a generalist who overpromises.

But for elevator parts? Specifically for core components like door operators, controllers, and safety brakes? Stick with the OEM. The 'expensive' option.

When the 'cheap' path actually makes sense

But I'm not a zealot. If you have a low-traffic service elevator that's used twice a day, a high-quality aftermarket part is probably fine. Or if you're budgeting for a building that's scheduled for demolition in 2 years, the TCO math flips.

My rule of thumb: If the elevator moves people more than 50 times a day, or if downtime causes real business pain, buy genuine. Period.

If it's a utility elevator moving inventory once a week? That's where you can take calculated bets.

This was accurate as of Q4 2024. Pricing and part compatibility in the elevator industry changes fast, so verify current rates before budgeting.
