You step into your home elevator, coffee in hand, ready to whisk upstairs—only to feel every bump and rattle, like you’re in an old pickup truck. Frustrating, right? What if every ride felt as smooth as skating on fresh ice?
That’s why we at LJ Elevator built the UNA Series. We didn’t just tweak existing designs—we reinvented them, packing four breakthrough comfort features into one elegant lift. No other home elevator on the market offers this level of stability, silence, and precision. It’s our proudest achievement, and it shows in every quiet, steady glide.
Curious how we did it? Let me walk you through each of those technologies and explain why UNA isn’t just a lift—it’s a whole new way to move.
Three-center balanced design
What it is: We align three critical centers—the guide-center, the suspension-center, and the cabin-center—along a single vertical axis.
Why it matters: Most home elevators have only a rough alignment, so even small imbalances cause cabin sway or vibration. UNA’s three-center precision is a proprietary LJ Elevator engineering technique.
How you benefit: From the moment you step in, you’ll feel zero side-to-side sway. We’re so confident in our balance that you can even test UNA in “sport mode” by jogging in the cabin—the car doesn’t wobble. No other manufacturer offers this level of cabin equilibrium in a home elevator.
Gold-eBelt traction belt
What it is: The heart of our drive system is the Gold-eBelt—a steel belt wrapped in a high-performance TPU compound we developed in-house.
Why it matters: Standard steel cables or generic belts stretch, slip, and transmit noise into the cabin. Our Gold-eBelt never stretches beyond 0.1 % under full load, so starts and stops are incredibly smooth.
How you benefit: You’ll notice no jerks or clunks—just a continuous, whisper-quiet acceleration. In an independent lab test, UNA registered 45 dB quieter at startup than leading competitor models. That’s the difference between a hushed whisper and a dull murmur—comfort and peace of mind you won’t find anywhere else.
Large-diameter drive wheel
What it is: Our custom drive wheel (sheave) is 30 % larger in diameter than standard home elevator wheels, optimized through finite-element analysis to reduce dynamic vibration.
Why it matters: A larger wheel turns slower for the same lift speed, which directly cuts mechanical vibration and noise. Plus, its aerospace-grade aluminum core ensures perfect roundness under all loads.
How you benefit: The cabin remains virtually vibration-free—even at high speeds. During independent ride tests, passengers couldn’t detect any perceptible vibration below 0.2 mm/s², far exceeding the ISO comfort standard of 0.8 mm/s². This isn’t theoretical bragging—our customers regularly tell us they feel as if they’re gliding on air.
Perfect stops—every time
What it is: UNA’s Digital Direct-Leveling uses ultra-fast microcontrollers and high-resolution sensors to adjust speed and position in real time as you approach each floor.
Why it matters: Traditional elevators use coarse “seek and adjust” logic, resulting in small overshoots or undershoots. UNA’s algorithm monitors cabin position at 1,000 times per second, making micro-adjustments in braking torque for pin-point accuracy.
How you benefit: You’ll step out onto the landing level within ±2 mm, eliminating trip hazards and making life easier for wheelchair users, the elderly, and anyone carrying delicate items. Other home elevators can’t match this precision—most claim ±10 mm at best. We believe your elevator should perform better than any competitor’s commercial model—and UNA delivers.
Why UNA Series stand alone?
Patented Innovations: Each of these features is protected by our patents, ensuring you get true LJ Elevator exclusives—no copycats.
End-to-End Quality: From R&D to installation, we oversee every step. Our global remote-support team guides overseas clients through installation, commissioning, and troubleshooting.
Customer-First Testing: Before any UNA unit ships, we run a 12-point comfort test, including load variance, temperature extremes, and noise profiling. If it doesn’t pass our own “home-use simulation,” it doesn’t leave the factory.
Conclusion:
At LJ Elevator, we believe that true luxury lies in the details you barely notice—until they’re gone. The UNA Series isn’t just another home elevator. It’s our commitment to bring you the smoothest, quietest, most stable ride imaginable, backed by over 20 years of vertical-transport expertise.
If you’re ready to offer your family—and your property—the ultimate in ride comfort and reliability, let’s talk. Contact us for a personalized virtual demo or visit one of our experience centers. Once you experience UNA, you’ll never look at home elevators the same way again.
