NINGBO SIGMA Hydraulic Passenger Elevator

NINGBO SIGMA Hydraulic Passenger Elevator

A passenger elevator (or lift) is an essential vertical transportation system designed to efficiently and safely move people between different floors of a building. As a cornerstone of modern architecture, elevators enable accessibility, convenience, and time-saving mobility in high-rise buildings, commercial complexes, residential towers, hospitals, hotels, and public infrastructure.

With advancements in engineering and smart technology, today’s passenger elevators offer smooth rides, energy efficiency, cutting-edge safety features, and customizable designs to meet diverse architectural and user needs.

Key Components & Working Mechanism

1. Elevator Cab (Car)

• Designed for comfort and safety, available in various sizes (4 to 50+ passengers).

• Interior finishes include stainless steel, glass, wood, or premium laminates.

• Features non-slip flooring, handrails, LED lighting, and ventilation for passenger comfort.

2. Drive Systems

• Traction Elevators (Geared/Gearless):

  • Use steel ropes, counterweights, and electric motors.

  • Ideal for mid to high-rise buildings (up to 150+ floors).

  • Gearless systems offer smoother, faster, and quieter operation.

• Hydraulic Elevators:

  • Operate via pistons and hydraulic fluid.

  • Best for low-rise buildings (2–6 floors) due to slower speeds.

  • Require a machine room but are cost-effective for small buildings.

• Machine-Room-Less (MRL) Elevators:

  • Compact, energy-efficient, with machinery inside the shaft.

  • Popular in modern buildings due to space-saving benefits.

• Vacuum (Pneumatic) Elevators:

  • Use air pressure differences for movement (no cables or pit required).

  • Transparent tubular design for aesthetic appeal in homes.

3. Control & Navigation Systems

• Destination Dispatch Control (Smart Grouping):

  • AI optimizes elevator routes, reducing wait times in high-traffic buildings.

• Touchless & Voice-Activated Controls:

  • RFID, smartphone apps, or voice commands for hygienic operation.

• Automatic Landing & Door Sensors:

  • Ensures precise floor alignment and prevents door accidents.

4. Safety Features (Critical for Passenger Protection)

• Emergency Braking System (prevents free-fall in case of failure).

• Overload Sensors (prevents operation if weight exceeds capacity).

• Fire-Rated & Earthquake-Resistant Models (for disaster-prone areas).

• Backup Power (UPS/Battery) to ensure operation during outages.

• Emergency Alarm & Intercom for immediate assistance.

5. Energy Efficiency & Sustainability

• Regenerative Drives feed unused energy back into the building’s grid.

• LED Lighting & Sleep Mode reduce power consumption.

• LEED & Green Building Certified options available.

Types of Passenger Elevators Based on Application

1. Residential Elevators

• Compact, silent, and stylish for homes, villas, and apartments.

• Options include hydraulic, pneumatic, or MRL models.

2. Commercial Elevators (Offices, Malls, Hotels)

• High-capacity, durable, with destination dispatch for efficiency.

• Glass elevators for luxury hotels & shopping centers.

3. Hospital & Medical Elevators

• Wider cabins for stretchers & wheelchairs.

• Antibacterial coatings & easy-to-clean surfaces.

4. High-Speed Elevators (Skyscrapers & Towers)

• Speeds up to 20+ m/s (45+ mph) for ultra-tall buildings.

• Pressure control systems for ear comfort at high speeds.

5. Accessible (ADA-Compliant) Elevators

• Wider doors (≥ 36 inches), braille buttons, voice announcements.

• Compliant with Americans with Disabilities Act (ADA) & EN 81-70.
