KONE Elevators: Answering Your Most Common Questions (And a Few You Didn’t Know to Ask)

When I first started reviewing elevator installations, I assumed every brand’s sliding door mechanism was basically the same. A few field failures later — and I still kick myself for not catching that spec early — I learned the hard way how much detail matters. Here are the questions I hear most often, plus a couple that surprise people every time.

What makes KONE elevators different from other brands?

From a quality inspection standpoint, the biggest difference is consistency. KONE’s sliding door assemblies (the ones you see every day in lobbies) have a tolerance spec that’s tighter than what many local installers are used to. In Q1 2024 alone, I rejected 12% of first deliveries because door gap measurements exceeded the 2mm maximum. The manufacturer fixed them at their cost. But that kind of consistency — in door alignment, signal timing, and cab finishing — is what keeps a building’s vertical transportation feeling professional.

Is KONE available in Ghana?

Yes. KONE has an active presence in West Africa, including Ghana. I worked on a project where we specified KONE elevators for a new high-rise in Accra — the main challenge was logistics lead times (shipping in long-lead components added about 6 weeks). But the local support team handled commissioning well. If you’re planning a project there, I’d recommend verifying which spare parts are stocked locally (unfortunately). Not all models have full coverage yet.

Does KONE service the St. Louis area?

KONE has offices and service centers in major US cities, and St. Louis is covered under their Midwest region. I’ve reviewed maintenance contracts for properties in the Metro East area — they offer full maintenance, modernization, and 24/7 call-out. One thing to check: whether your building’s existing controller is compatible with KONE’s dispatch algorithms. Some older installations might need a retrofit board. That’s fairly straightforward, but the cost (around $3,500–$5,000 per unit) should be budgeted upfront.

Why are sliding doors common in KONE elevators?

Sliding doors (center-opening or side-opening) are the industry standard for passenger elevators because they save shaft space. KONE uses a patented counterweight system on many models that reduces the force required to open/close. In my audits, I’ve seen far fewer pinch-point issues with their design compared to some third-party door operators. The mechanism itself is surprisingly simple — a belt-driven system with a magnetic clutch. Period. No complex hydraulics. That means fewer things to break.

Can you use a LiftMaster garage door opener on a KONE elevator door?

Short answer: no, and please don’t try. I’ve actually seen a building manager ask this — they thought they could save money by using a universal opener. Here’s the thing: elevator doors have specific safety requirements (monitoring the door lock circuit, reopening if obstructed, and meeting fire resistance ratings). A residential opener (i.e., LiftMaster) doesn’t comply with ASME A17.1 or EN 81-20. The voltage and logic are completely different. Using one would void your insurance and potentially create a serious hazard. Stick with the OEM door operator — from my perspective, that’s non-negotiable.

Can you paint vinyl siding to match an elevator cab?

I get this question surprisingly often from building owners who want to reuse interior panels. Vinyl siding is not designed for interior use — it’s an exterior cladding material (weather-resistant, UV-stabilized). Painting it for an elevator cab is possible but inadvisable. The paint won’t bond well to the existing surface without aggressive sanding and primer, and even then, the finish will probably chip under passenger traffic. Plus, vinyl siding doesn’t meet the smoke/fire spread ratings required for elevator interiors (ASTM E84 Class A or B). If you need a low-cost cab refresh, consider laminate panels or metal skins instead. I regret not telling a client this earlier — they spent $2,000 painting their lobby panels and had to replace them within a year.

What should I consider before modernizing an old elevator?

Five years ago, a full modernization meant ripping out all the machinery and installing a new system. Today, KONE offers modular modernization kits that replace only the controller and door operator — the cab, rails, and hoist ropes can often be reused. The industry is evolving fast. What was best practice in 2020 (full replacement) may not apply in 2025. In my experience, the biggest decision factors are: (a) the age of your existing motor — is it still serviceable? (b) whether you want energy-regenerative drives (KONE’s EcoDisc motors are worth the premium, from a long-term cost perspective), and (c) building traffic patterns. A good modernization contractor will do a traffic analysis first. Simple.

How does KONE ensure quality in its installations?

From the inside: every KONE elevator goes through a commissioning protocol that includes 200+ checkpoints. I’ve reviewed that list — it covers everything from door dwell time (3–5 seconds adjustable, FYI) to vibration levels in the car (<0.15 m/s² peak). But quality also depends on the installer. I’ve rejected KONE equipment only twice in four years — both times because the local contractor hadn’t calibrated the door closing force correctly (target is 135N max per EN 81-20). KONE’s own factory audits are solid, but they rely on us (quality managers) to catch field errors. That’s why I always recommend having a third-party inspector on large projects. Probably worth the extra $2,000–$3,000 for peace of mind.
