Sigma passenger lift in Bangladesh

Passenger elevators (lifts) are engineered systems designed to transport people efficiently between floors in residential buildings, commercial buildings, and high-rise buildings. Unlike freight elevators, these prioritize human safety, comfort, and energy efficiency while enabling architectural innovation. Modern systems integrate AI-driven dispatching, regenerative drive technology, and space-saving designs to optimize vertical transportation performance.

Core Elevator Components & Technical Specifications

• Elevator Car: Stainless steel or glass cabins (630kg to 5,000kg weight capacity)

• Drive Systems:

  • Gearless traction (buildings >10 floors)

  • Hydraulic (2-6 floor buildings)

  • Machine-Room-Less (MRL) for space efficiency

• Safety Systems:

  • Dual electromagnetic brakes

  • Overspeed governors (EN 81-20 certified)

  • Seismic sensors for earthquake zones

• Control Technology:

  • Destination dispatch AI

  • IoT-enabled predictive maintenance

  • Touchless operation interfaces

Performance Across Building Types

Energy Efficiency Breakthroughs

Modern elevators reduce power usage through:

1. Regenerative Drives: Convert braking energy into reusable electricity (up to 35% savings)

2. LED Lighting & Sleep Mode: Consumes <15W during inactivity

3. VVVF Motor Control: Precise speed adjustment reduces waste

4. Lightweight Materials: Carbon fiber components cut operational load
