Re: Building our dream house
Posted: November 22nd, 2021, 8:58 pm
We completed our 3rd floor slab. And since we had built duplex in 2nd floor (ground and first floor for rent),our in-laws were pressurising us to go for lift option. Initially we were reluctant ,but after pressure from almost everyone we decided to go for lift.
So we started scouting for lift. But since we have already built 4 floors ( G+ 3), we had many restrictions. Let me put them here ,
1) Most of the lifts installed uses traction control which require a pit at bottom (generally 3-5 feet) and a lift room (at least 10 feet height). They are faster and can carry load for higher heights. However for homes, lower speeds are considered and height can be maximum G+2 or G+ 3 for which hydraulic lifts are good enough.(hydraulic lifts have their own problems like oil leakage issues, jerks and less efficient than traction).
2) But we required a lift only for G+2 and we did not want to break anything on 3rd floor. So we had practically zero overhead space and since we had not planned for lift, we had a limited area in pit. So hydraulic lift was only option.
3) so first challenge was to find a place to keep lift (generally a decent size lift would require 5 x 5 feet internal space ). Luckily we found a spot where we could break open slab without compromising on structural safety and mainly no beams. Then we called many company representatives to check for feasibility.
So our findings was
1) we can have hydraulic lifts with just 1 feet pit depth and zero overhead space (ceiling has to be at least 9 feet ).There are lift companies like one from thyssenkrupp and ciebles which just require just 12 cm pit depth and no over head space. But thyssenkrupp (elite elevator)and ciebels lift are expensive as they are imported from Europe directly )
2) There are no safety standards for home elevators in india. Thyssenkrupp elevators(elite ) elevator ringed all bells like No pit (12 cm) and no overhead space, low power consumption and high safety standards. But price are too high. The sales guy quoted 20.6 lakhs for a hydraulic lift(base model ) inclusive of gst, transportation and installation . That seemed too high for us. They probably were willing to reduce 2 lakhs more, however 18 lakhs still looked high for us.
3) Then we started looking for other companies. We called TK elevators(Thyssenkrupp ) Indian branch who said they don't have any hydraulic elevators to offer at all which seemed strange as they have allowed another agency elite elevators to market it's hydraulic products which are imported.
4) When we heard of high prices, we decided to put all the structure required for lift and then when budget agrees we shall go for it. But after being convinced that lift is now a real possibility we continued our search. We started checking other vendors via indiamart.We also did not want to get into single vendor situation and that too who just imports it(what of he shuts his import business which is quite possible ).
5) Then many company representatives started calling us and visiting our house for feasibility and sales .Main one was Usha elevator. They said they wanted at least 1 feet in pit area for safety reasons. Primarily they will place rubber pads in pit area which will try to protect people inside lift when everything else fails. They did feasibility check and okeyed our house for lift errection.however they are yet to give quotations.
6) Few other lesser known companies gave quotation ranging from 6 to 10 lakh.
7) We also had 2 peculiar requirements. We wanted entry in ground floor in one direction and exit at top in direction adjacent to it I.e entry in East and exit in South. The lift companies told me, entry ,exit in 3 directions are also possible. They need 1 wall or 1 side for shaft. They did say that 2 door lifts are indeed common.
8) Since lift opens in parking area and exit is directly into our house bypassing main door, we wanted high security entry. Lifts nowadays has password access, biometric access , RFID access and keys for security. We have not decided on which mode, however we will avoid password access as it's the easiest way to hack (any peeking intruder can observe the code ).
9) lifts can accommodate more weight and have more space if we opt for swing door instead of sliding doors. As sliding doors require 2 doors , it takes valuable space and also has weight penalty. So do consider swing door for homes if you want more spacious cabin and more weight capacity.
10 ) hydraulic lifts have low speeds like 0.15 ms and so on. All technicians told to keep speed in home elevators to a decent one as it will be used by elders more frequently. Thyssen krup had limited speed to 0.15 to 0.4 m/s for same reason. However other company representative told they can increase or decrease speed based on client requirement..
11) because after construction lift errection are so high, lift companies try to cater this market with high customization. One guy told me that they even built 1.5 x 4 feet lift which can accommodate 2 people..So do not worry about space if you want to get lifts fitted. Call the sales guy and probably they will give good ideas.
All in all, we felt we are lucky that we considered lift at least now. Now our cost for breaking slab and others would hardly cost 25 k. The same would have costed 10 lakhs post construction. At least it was not too late.
The lift thing was running in my mind and was bugging us after every other person kept on pointing on that as we had built duplex house in 2nd floor. Now we are quite relieved that it is indeed possible and we can walk away fr on those worries. Sometimes home construction is both a headache as well as smiles. All is well that ends well. I will definitely keep you guys updated on happenings on this subject
