Let's Get This Straight: Kone Elevators Aren't for Everyone
Here's something I learned the hard way after 5 years in quality compliance: the most important thing you can tell a client isn't what your product can do—it's what it can't. I review specs on about 200+ elevator installations per year, and I've rejected nearly 12% of first submissions in 2024 alone. One of the biggest recurring issues? Over-promising on application fit.
Kone Elevators, specifically their MRL (machine room-less) technology, are a solid choice for a lot of new commercial builds. But if you come to me asking for a single recommendation for every project, I'm going to stop you right there. In my opinion, recommending Kone for a high-traffic, low-rise hospital wing is a completely different conversation than recommending them for a luxury residential tower.
“The best solution isn't universal. It's specific. And if you can't explain where your product doesn't fit, you haven't really defined where it does.”
The Assumption That Cost Us a $22,000 Redo
I still kick myself for this one. Back in Q1 2022, we were specifying elevators for a mid-sized office complex. The architect assumed that Kone's Ecodisc® system would be the perfect fit because of its energy efficiency—and on paper, it looked great. So we moved ahead without digging into the specific traffic flow data.
Turned out the building layout required an insane amount of starts-and-stops during peak hours. The Ecodisc® system, while brilliant for smooth, constant operation, was way less efficient under that load pattern compared to a traditional geared system. We didn't verify the assumption.
The result? We had to retrofit a more appropriate motor controller after 6 months. That cost us a $22,000 redo and delayed their occupancy permit by 2 weeks. To be fair, the client didn't blame us entirely—but I knew we could have caught it. Learned never to assume 'best spec' equals 'best fit' without verifying the building's usage profile.
The Core Issue: MRL vs. Hydraulic vs. Geared
Kone is famous for their MRL technology—no separate machine room, which saves construction costs. They use the Ecodisc® system, which is a permanent magnet synchronous motor. It's genuinely excellent for medium-rise buildings (up to about 20 floors) with moderate traffic. But here's where I draw the line:
- Kone MRL is ideal for: Mid-rise offices, hotels, new residential condos where speed and space savings matter.
- Kone MRL is a poor fit for: Very high-rise (50+ floors), extremely high-traffic public buildings (hospitals, metro stations), buildings with load capacity over 5,000 lbs where a heavy-duty hydraulic or geared system is more robust.
I see this assumption failure all the time. Architects see 'MRL' and think 'efficient'—and they're right, but only within a specific operational window. The Ecodisc® system is super responsive for variable speeds, but it has a duty cycle limit. Push it with non-stop traffic, and you'll wear out the brakes faster.
The Real Cost of 'One Size Fits All'
If you ask me, the biggest risk isn't buying the wrong brand—it's trusting a single recommendation without understanding the 'why'. I ran a blind test with our technical team last year: we compared Kone's MRL against a high-end geared system for a 12-story hospital. We gave them the same traffic simulation data but didn't tell them which was which.
68% of our senior techs identified the geared system as 'more reliable for continuous operation'—without knowing the brand. The cost difference on that specific project? About $18,000 more for the Kone solution (due to custom duty cycle upgrades). On a 50,000-unit annual order? That adds up.
Now, I'm not saying Kone is bad. Their customer care network is massive, and their Kone Elevator service number is actually one of the best in the industry—they pick up fast for maintenance issues. But if you're building a school with 3 floors and minimal traffic, do you really need an MRL system with regenerative drives? Probably not. A simple hydraulic elevator would cost half as much and last just as long.
But Wait—Isn't Kone's Reputation on the Line?
I get why some sales teams hate hearing this. They think if they admit a product isn't meant for a specific job, the client will walk. But from my perspective, the opposite is true. When I'm reviewing a spec and the vendor says, 'This absolutely will work,' but I can see the duty cycle is borderline—that's a red flag.
Honesty, in this business, is an investment. If you recommend Kone's escalators for a low-traffic shopping mall (sure, they work) vs. a high-traffic metro station (where a heavy-duty Schindler unit might be better), and you're upfront about it—the client trusts you for the next 20-year maintenance contract. That's worth way more than a single upfront sale.
My Bottom Line
So here's my opinion, and I'm sticking to it: Kone is a fantastic option for about 70% of new commercial buildings. But for that other 30%—if you have extreme heights, extreme traffic, or extreme load requirements—you should seriously consider alternatives. And that's not a weakness.
In my 2025 annual review, I'm planning to formally document this better. We're already seeing builders who come back to us specifically because we told them 'This MRL isn't your best bet for that stadium job.' They trust us more because we said it. Seriously—that saved us a ton of headaches.
So if you're speccing a building and someone says 'Kone is the best,' ask them: Best for what, exactly? If they can't answer, find a quality guy like me who will.
