India's independent resource for everyone who deals with lifts. Residents and owners come for plain-language guides on how lifts work and stay safe. Policymakers come for the latest lift regulations, standards, and technical documents. Dealers and engineers come to understand the technologies behind modern lifts — backup systems like the ERD among them. Vendor-neutral and openly sourced.
The same independent knowledge, organised for whoever you are — the one place that serves residents and the trade alike.
Plain-language dos & don'ts: what to do if you're stuck, weight limits, monsoon and child safety.
Sizing, battery selection, AMC scope and total cost — vendor-neutral, with a free calculator.
Full specifications by lift type, motor KW and voltage — the trade knowledge no brand shares openly.
Lift regulations, the Haryana Act, standards, and a living, sourced record of accidents across India.
Independent, vendor-neutral guides for buyers, residents and building owners — from choosing the right lift to keeping it safe and serviced. We don't sell lifts.
An independent selector — enter your floors, passengers and building type and get the right lift type, capacity, speed and an honest price idea. We don't sell lifts.
How a lift actually moves, the types — traction, MRL, hydraulic — the key parts, and the safety systems that stop a lift from falling. In plain English.
What to do if you're stuck, fire and monsoon rules, child safety, and the warning signs a lift needs service. Free and vendor-neutral.
How often to service a lift, what a good AMC must cover, comprehensive vs non-comprehensive, real India cost ranges, and the red flags before you sign.
The everyday safety basics no brand brochure bothers to spell out — for anyone who rides, owns, or manages a lift. Independent and free.
Most lifts simply stop when the power fails. We cover the backup-power options without the sales pitch — from a basic Automatic Rescue Device (ARD) that limps the car to the nearest floor, to an Emergency Rescue Device (ERD) that keeps it running with no break at all. Independent explainers, full specifications, and a free sizing calculator.
India ranks #2 globally for elevator-related accidents. Haryana's 2020 amendment is the only state law that actually mandates uninterrupted lift backup. Every other state still tolerates the dark, stalled, sealed cabin.
The questions people type into ChatGPT, Gemini and Google about lifts, backup, safety and the law — answered plainly, with sources. Independent and vendor-neutral.
Stay calm and stay inside — never try to climb out of a stalled cabin. Use the alarm or intercom, call the building's emergency / lift-service number, and wait for trained help. Forcing the doors is a leading cause of serious lift injuries.
Only if it has a backup system. Modern lifts include an Automatic Rescue Device (ARD) that moves the cabin to the nearest floor and opens the doors when power fails. Continuous-run backup (a lift inverter / ERD) is an optional upgrade that keeps the lift running through the outage. Only Haryana currently mandates uninterrupted backup.
There is no national mandate. Haryana's 2020 amendment is the only state law requiring uninterrupted lift backup, for buildings above 15 metres. Other states require licensing and inspection under their Lift Acts, but not continuous backup.
It's a backup power system for a lift. A basic ARD lowers the cabin to the nearest floor on power failure; a lift inverter / ERD can keep the lift running normally during an outage. The right size depends on the lift's motor rating — our calculator works it out.
Liability can fall on the building owner or society, the maintenance (AMC) contractor, the installer, and the manufacturer. Criminally, death by negligence is covered by Section 106 of the Bharatiya Nyaya Sanhita (up to 5 years); civilly, poor maintenance is a 'deficiency in service' under the Consumer Protection Act, 2019. (Informational, not legal advice.)
Usually yes. A lift accident is an 'accident', so a personal-accident policy generally pays for accidental injury or death, health insurance covers the hospitalisation, and life cover pays on death — subject to your policy's terms. The building's public-liability cover may also apply.
Haryana mandates a minimum of 15 minutes; most engineers specify 30 minutes. The exact battery sizing depends on the lift's motor KW and how many lifts share the system.
Keep an annual maintenance contract (AMC) active with scheduled visits, insist on a written service logbook, and report any jerks, odd noises, or mis-levelling immediately. A maintained logbook is also key evidence if anything ever goes wrong.
