Residential Elevator & Home Lift Shaft Specs: Hydraulic vs Traction MRL for G+3/G+4 Villas
Spoken by: AGNAA MEP & Vertical Transportation Team
Primary Reference: IS 14665 Electric Traction Lifts Code & NBC 2016 Part 8
Direct Answer (AGNAA Engineering Standard)
Home elevators for G+3 and G+4 villas require a minimum lift shaft dimension of 1500mm x 1500mm (5x5 ft) for a 4-passenger (300 kg) capacity. AGNAA Design Studio specifies Machine Room-Less (MRL) gearless traction lifts for high speed and energy efficiency, requiring a 1200mm pit depth and a 3600mm top overhead clearance.
Executive Key Takeaways
- MRL Gearless Traction Lifts: 50% more energy efficient than hydraulic lifts with smoother travel.
- Hydraulic Lifts: Ideal for retrofit installations requiring minimal 300mm pit depth.
- Standard 4-passenger (300 kg) lift shaft: 1500mm x 1500mm clear internal dimension.
- Automatic ARD (Automatic Rescue Device) brings elevator to nearest floor during power outages.
- Panoramic glass lifts enhance atrium vertical aesthetics in open-plan luxury staircases.
Frequently Asked Questions
Does a home elevator require a separate machine room on the terrace?
Modern MRL (Machine Room-Less) lifts store the gearless motor directly inside the top of the lift shaft, eliminating the need for a separate rooftop machine room.
How deep must the elevator pit be dug during foundation work?
MRL traction lifts require a 1200mm (4 ft) deep waterproof RCC pit. Hydraulic lifts require only a shallow 300mm–500mm pit.
