When selecting an passenger elevator for mid-rise buildings or high-traffic public spaces, simply choosing an elevator that can move up and down is far from sufficient. What you need is a solution that balances safety, smooth operation, energy efficiency, and flexible installation, all while staying within a limited budget. With this in mind, LJ Elevators has introduced the ECO-C series: a traction-driven passenger elevator designed to achieve the perfect balance between actual performance and cost control, while maintaining quality.
A Solution That Adapts to Your Building
We understand that no two buildings are exactly alike. Some buildings have space reserved for machine rooms, while others do not. To meet these diverse needs, ECO-C offers two options:
Machine Room (MR):
In the MR configuration, the traction machine, control panels, and associated equipment reside in a small, dedicated machine room above the shaft. This traditional layout:
- Simplifies routine maintenance: Technicians can access drive components directly, reducing service time.
- Controls sound and vibration: The machine room isolates noise away from occupied floors—ideal for hospitals or luxury apartments.
- Supports taller travel: When rooftop or penthouse space is available, the MR design provides maximum headroom and performance.
Machine Room-Less (MRL):
When rooftop space is limited or you prefer a seamless building façade, the MRL design integrates all drive equipment into the hoistway’s overhead space:
- Saves construction cost and space: No separate machine room means lower civil-work expenses and more usable rooftop area.
- Speeds up installation: With fewer structural requirements, installation timelines shrink—perfect for renovations or tight schedules.
- Maintains full performance: Despite the compact footprint, MRL delivers the same load capacities, speeds, and safety features as the MR version.
Whether your building is suitable for MR or MRL, our ECO-C series can perfectly adapt to your building structure.
Engineered for Comfort
At the heart of ECO-C is a gearless PM traction motor and an intelligent drive controller. This combination delivers:
- Continuous smoothness: no abrupt starts, no sudden vibrations. From the first to the last passenger, every ride is as smooth as gliding.
- Low-noise operation: Vibration and noise levels are both below 50 decibels—lower than the volume of everyday conversation—because we equipped soundproof cotton for each cabin.
- Precise level control: Advanced sensors maintain car stopping accuracy within ±5 millimeters, eliminating tripping hazards and enabling wheelchair-accessible access.
For building managers, this means reduced elevator quality complaints, reduced track and component wear, and extended maintenance cycles.
Safety Systems
Your reputation depends on safe, dependable elevators. ECO-C incorporates multiple safety nets that engage automatically:
- Overspeed Governor & Safety Gear: If the car ever exceeds its rated speed, the governor triggers the safety gear to bring the elevator to a gentle, controlled stop.
- UCMP (Unintended Car Movement Protection): As soon as any door—car or landing—begins to open, the drive system locks the car in place, preventing accidental movement.
- Light Curtain Door Protection: Infrared beams across the doorway detect obstructions in under 0.5 seconds; doors reopen instantly to avoid pinching.
- Emergency Rescue Device (ARD): If power suddenly, the car automatically descends to the nearest floor, opens its doors, and allows safe evacuation.
- Overload Detection: If passengers or cargo exceed rated capacity, the elevator refuses to move and sounds an audible alarm until the load returns to safe limits.
Because these safeguards operate together, ECO-C delivers peace of mind for property owners, alongside verifiable compliance with international safety codes.
Energy Efficiency
In busy buildings, elevators account for a significant portion of energy consumption. ECO-C tackles this with:
- Regenerative Drive Option: Captures braking energy and returns it to the building’s power grid, cutting net electricity use by up to 30%.
- LED Cabin and Hallway Lighting: Uses 60% less energy than fluorescent fixtures, with lifespans exceeding 50,000 hours.
- Standby Sleep Modes: When idle, lighting dims and fan systems pause, further reducing draw without delaying readiness.
Over the typical 20-year service life, these features can save thousands in utility costs—money you can reinvest in building upgrades or operational reserves.
Quick Installation
We know that getting an elevator installed quickly and servicing it easily are just as important as its technical specs. With its modular design and common, off-the-shelf parts, the ECO-C can be set up faster, and its components can be accessed more easily for routine maintenance.

| Pit Depth (P) | 1600–2100mm | 1400–1700mm |
2. Factory Preassembly & Clear Parts Labeling
Before shipping out from factory, each ECO-C elevator undergoes a partial dry-run assembly. We reassemble key components—cabin, car frame, door operator—to film quality-control videos. This not only verifies fit and finish but also lets you see exactly how your elevator should look.
Every single part is then tagged with clear English labels. That way, when your installation team arrives, they can match each component precisely—no mystery parts left over, no guesswork. This labeling system was born from experience: in past projects, unmarked parts led to incorrect installs and hidden safety risks. With ECO-C’s labels, every bolt and beam finds its correct place easily and safely.
3. Comprehensive Documentation & Remote Support
Alongside labels, we supply detailed assembly manuals, CAD drawings, and video guides. For overseas or remote sites, our engineers deliver live, web-based walkthroughs. Whether it’s confirming pit dimensions or checking door operator wiring, we guide you step by step—no confusion, no delays.
Enhancing Building Value
Choosing ECO-C isn’t simply about meeting minimum specifications. It’s about:
- Elevating Occupant Experience: Smooth, quiet rides improve tenant satisfaction and can command higher rents or occupancy rates.
- Safeguarding Reputation: A robust safety record enhances your property’s brand and reduces liability risk.
- Managing Budgets: Competitive pricing and low running costs ensure healthy margins—even in cost-sensitive developments.
In short, ECO-C helps you deliver premium functionality without the premium price tag.
Conclusion：
The ECO-C series is designed to fit any building need – whether you require a machine room (MR) or machine room-less (MRL) design, the ECO-C gives you the best experience of quiet, smooth operation and energy conservation within your budget. Each component is pre-assembled and clearly labeled at the factory, so your team can quickly and accurately install and maintain the elevator.
