Traction Gearless Elevator – Machine Room Less (MRL)

Key Features

• Space-Saving MRL Architecture: Eliminates the machine room by integrating traction/drive equipment within the hoist way/overhead zone - ideal where space optimization and clean rooftop planning are priorities (as per site feasibility and layout).
• High-Efficiency Gearless Traction (PMSM): Gearless PMSM machine delivers smooth, low-noise operation with reduced mechanical wear and long service life.
• VVVF Drive Control: Precision speed regulation with controlled acceleration/deceleration for premium ride comfort and reduced mechanical stress.
• Microprocessor-Based Controller: Intelligent control with fault indication, protection logic, event logging, and optional diagnostics/monitoring (if specified).
• Fully Automatic Operation: User-friendly COP/LOP controls with automatic door opening/closing and standard operating logic.
• Premium Ride Comfort (Low-Jerk Motion): Optimized motion profile for soft starts/stops - comfortable for daily passenger usage.
• Accurate Floor Levelling: High-precision levelling for flush landing alignment, smoother entry/exit, and reduced trip hazards.
• Energy-Efficient System: Efficient gearless drive and smart control logic help minimize power consumption and running cost (as per configuration).
• Safety and Compliance Ready: Engineered with integrated safety circuits and protections aligned to applicable statutory requirements and project specification.
• Optimized Civil Footprint: Designed for modern buildings with reduced civil space requirements, subject to shaft/headroom constraints and final engineering.

Safety Features

• Overspeed Governor and Progressive Safety Gear:Continuously monitors speed and automatically activates safety gear for safe deceleration and stopping during overspeed conditions.
• Ascending Car Overspeed Protection Means: Protection mechanism to detect and stop uncontrolled ascending car overspeed, as required by applicable standards (as applicable).
• Unintended Car Movement Protection (UCM/UCMP): Detects unintended movement away from the landing with doors open, stops the car, and keeps it stopped to enhance passenger safety at landings (as applicable).
• Landing Door Interlock with Lock Monitoring: Lift movement is permitted only when all landing doors are closed and locks are electrically proven through the safety circuit.
• Car Door Opening Restriction (Anti-Fall Protection) : Prevents unsafe door opening when the car is outside the unlocking zone.
• Infrared Light Curtain (Door Protection): Full-height non-contact protection that detects passengers/objects and re-opens doors during closing.
• Door Force Detection: Monitors closing resistance; on contact/obstruction, doors stop and re-open to minimize impact (where provided).
• Electro-Mechanical Brake System: Fail-safe braking for reliable stopping and holding (redundancy where provided).
• Final Limit Switches (Top and Bottom): Independent end-travel cut-out protection; reset by authorized service personnel after inspection.
• Buffers (Car/Counterweight): Energy-absorbing buffers reduce impact forces in the event of over-travel.
• Overload Protection: Detects overload and inhibits operation with audible/visual indication until load returns within rated capacity.
• Emergency Alarm Bell: Audible alarm from the car (and service access points as applicable) to alert for assistance during emergencies.
• Two-Way Emergency Communication (Intercom): Enables communication for rescue/maintenance assistance; designed to operate on emergency/backup supply as per applicable requirement.
• Remote Alarm / Rescue Communication: Two-way voice communication and remote alarm interface to a rescue service (optional where required).
• Emergency Lighting: Backup cabin lighting to support passenger safety during power interruption.
• Automatic Rescue Device (ARD): On mains power failure, brings the car to the nearest landing and opens doors for safe evacuation; provided as standard unless an approved alternate standby power supply with automatic changeover is available (as per IS 17900/local rules).
• Manual Rescue Arrangement: Enables authorized personnel to move the car to the nearest landing and evacuate passengers as per rescue procedure.
• Car-Top and Pit Safety Controls: Emergency stop switches and inspection/maintenance controls for safe servicing.
• Fire Recall / Fireman's Operation: On fire alarm/manual activation, the lift recalls to the designated floor, opens doors for safe exit, and switches to controlled emergency mode as per fire strategy (as applicable).
• Power Supply Protection: Phase failure/reversal, under/over-voltage and short-circuit protection with fault indication for safe, reliable operation.
• PMSM Motor Overheat Protection: Continuous temperature monitoring with protective alarm/shutdown to safeguard the motor (as applicable).
• Optional Seismic Safety System: Seismic sensor-based protective response (controlled stop/recall as configured) for earthquake-prone regions (if provided).
