Passenger Elevator

Engineering notes

Built around traffic, not around a single lift

Passenger lifts are specified as a system. We start from the building's population, the peak five-minute demand and the acceptable waiting interval, then size car capacity, speed and the number of units together. Quoting a single cabin without that analysis is how lobbies end up with queues at 8:55 am.

For two to eight units we supply group control with a common dispatcher; for larger banks, destination dispatch assigns passengers to a specific car at the landing terminal, cutting stops per trip and improving handling capacity by 15–30%.

Machine-room-less as the default

The gearless permanent-magnet machine mounts in the shaft head, so no plant room is needed — floor area that becomes lettable or usable space. Where a machine room already exists, conventional layouts remain available and are often the cheaper option for a retrofit.

The VVVF drive provides smooth acceleration and precise levelling, and an optional regenerative unit returns braking energy to the building supply, reducing elevator energy consumption by up to 30% in high-rise duty.

Interior and door options

Cars are built to the project's interior design: hairline or mirror stainless steel, etched or coloured panels, wood veneer, stone floors, and ceiling systems with indirect lighting. Handrails, mirrors, and ventilation grilles are integrated rather than added on.

Door options include centre-opening and two-panel side-opening configurations, with 800 to 1,400 mm clear openings, infrared light curtains, and door-holding and nudging functions for hospitals and hotels. Fire-rated landing doors are available for evacuation and firefighting requirements.
