In today’s world, where quality of life and safety are priorities, a high-performance home elevator is not just a symbol of modern living but also a trusted choice for family security. The Una Series Home Elevator, developed by LJ Elevator, features unique steel belt traction technology and comprehensive safety protection. It has become the preferred choice for many high-end residences and villas. Let’s explore the unique charm of the Una Series and help you understand, trust, and choose the best home elevator for your needs.
1. Ultimate safety
1. 1. One-touch self-rescue
Why is UNA regarded as the world’s safest home villa elevator? Because it introduces a revolutionary safety innovation that no other elevator company has ever achieved—a patented, exclusive one-touch self-rescue system. When a malfunction occurs, you simply press the self-rescue button, and the elevator automatically and gently moves to the nearest floor before opening the doors. This breakthrough technology empowers you to take control of your safety immediately, providing peace of mind during unexpected incidents.
1.2. Emergency power backup
Equipped with an ARD emergency power system, the elevator will automatically move to the nearest floor and open the door in case of a power failure, preventing entrapment.
1.3. Dual braking protection
- Mechanical safety clamp (AII06 model): Instantly grips the guide rail in an emergency, stopping the elevator cabin quickly and securely.
- Electrical braking system (EPS): If the traditional brake fails, EPS controls the cabin speed to about 0.05m/s, preventing accidents.
1.4. High-density light curtain & end station protection
- 154 Infrared beams: Provides higher sensitivity and full protection against door entrapment, exceeding the standard 94 beams in the market.
- Dual end station safety contacts: Uses durable physical contact technology to prevent interference, ensuring safe operation.
1.5. Non-door zone safety protection
Safety is paramount even when faults occur outside the immediate door area. With our industry-leading Non-Door Zone Safety Protection system, any fault detected in these areas automatically triggers a protective mechanism that locks the doors instantly—preventing any attempt to exit when conditions are unsafe. This innovative approach not only maximizes passenger security during unforeseen incidents but also reflects our technological leadership with exclusive patent protection, setting us far ahead of the competition.
1.6. Door zone safety protection
While most systems focus solely on fault scenarios, the UNA Series goes further to ensure comprehensive protection. Our Door Zone Safety Protection employs an anti-slip braking system designed to counteract any unintended cabin movement when the door is open. If the cabin shifts more than 5cm, the system rapidly engages to halt motion within 20cm, effectively neutralizing potential hazards. This critical innovation is backed by a national patent (Patent No. ZL200910112744.1, No. ZL201510692409.9), highlighting its unique engineering and the uncompromising safety standards of the UNA Series.
2. Quiet & comfortable ride
Super low noise
The Una Series adopts advanced steel belt traction technology. With a larger Φ150mm traction wheel, the rotation speed is reduced by nearly 50%, lowering noise levels to only 48 decibels, much quieter than national standards.
Smooth operation
- Triple-center design: Ensures perfect balance, preventing cabin shaking.
- T75 Solid guide rail + high-performance guide shoe: Provides strong resistance to deformation and extends guide shoe life by 30%, offering a stable and comfortable ride.
3. Flexible adaptation
The Una Series is designed with a high-performance steel belt traction system, making it suitable for both new buildings and renovation projects. Unlike most elevators on the market that require a pit depth of at least 400mm, the Una Series can be installed with a minimum pit depth of just 230mm—and in special cases, even as low as 200mm, with no additional cost. This makes it one of the most flexible solutions available, especially for renovation projects where pit depth is limited. No extra structure. No hidden upgrade fees. Just smart engineering that fits your home.
