pantograph forklift

[Blupower]

Good evening to all, I am an architect, a free professional who works in the province of power, I enrolled in order to ask you for advice
on a problem to give a solution.
are struggling with a renovation of a 19th century building,
and should vertically connect two mansarded environments to the housing
below, having environments turned and being there an opening
Existing of 85 cm x 110 cm I had thought of a pantograph lift,
that could flow on four corner guides.
the distance to overcome is 385 cm, and I would have the possibility to go under
floor of 60 cm approx.
is it possible with these measures to think of such a system?
at the limit I could also predict that everything closed dirty
18-20 cm and finish the race 18-20 cm below
the upper floor wire.
in this configuration I would take the race to about 345 cm.
this premise to have indications on feasibility and subsequently
to ask if you know companies/artigians in bari/foggia provinces
that can achieve this system.

thanks from now on for the indications I hope to receive.

Say hi.

an opening
Existing of 85 cm x 110 cm I had thought of a pantograph lift,
that could flow on four corner guides.
the distance to overcome is 385 cm

with these measures you need five " scissors " with interasse snodes about 1000 mm, with initial angle of about 6° and final of about 60°.
the mobile snode race is about 500 mm.
I think it's too much a dancer system (I think you want to use it as an elevator for people, don't you? ).
The pantograph is also a system which, as an accident, is always critical, both for the onboard load and for those near (the disposal points are not lacking).
angles (better if you use square tubulars) would be part of a counter-vented and carterized structure or do you think you see four " grissini" of four meters hanging from the ceiling to the floor?

Bye.

I thought of four angles acting as a stiffening structure,
(so opprtunamented) and do as a sliding rail
for the pantograph structure.
externally the structure would be closed with panels fixed on the 4 angles.
the purpose would be to bring maximum one person so
with a maximum capacity of 200 kg.
I see that you are of torino, it is my second homeland, (I studied and worked for 18 years), you know someone who can address me to realize this structure?

greetings and thanks.

I may give some advice:

1) I did not understand the question well. would you like to do a feasibility study and pass it to an artisan? and all the work in the middle of who does it?
2) designing a forklift is not a stupid thing, you should not only consider its kinematic operation, but also restability, reliability, possibility of maintenance, working conditions, mechanics, interface with the user (other than 'on' and 'down') and many other things
3) to this it is added that the device will be a machine, and it must be certified as a machine, but it is also a forklift for people transport, and it must be approved in this sense, verified by competent authorities, bla bla bla bla bla
4) Googlando a little, but really little I found these sites:http://www.ilclift.com/domesticlift.htmhttp://www.ceteco.it/prodotti.htm?ppc=google&name=miniscensorihttp://www.vimec.biz/home-comfort/prodotti/easy-living---elevatore-domesticohttp://www.aziende-italiane-siti.it...e-elevatore-montacarichi-servoscale-l571.htmlhttp://italian.alibaba.com/product-gs/home-elevator-02-245110759.htmlOkay, I'm not what you're looking for, but just to prove that there are people who design house elevators. these are tested, reliable, certified, maintainable and among other things certainly cost less of feasibility+design+realization custom+ made by something new.

I wonder, why dare you or want to reinvent hot water daily, especially by means of luck, without having at your disposal a pot, a stove, gas, without knowing what temperature boils and without knowing the effect of burns?

 

[Blupower]

thanks fulvio,
the problem is that I have already contacted several companies that operate in the sector,
but all after the inspection I propose the classic lift, but
is not installable in the particular situation, and in the end everyone recommends me
to address me to an artisan who can make the solution in question.
they have no chance to adapt to the spaces I have available,
they would redesign a new system, and this for the customer has costs
unsustainable.

Say hi.

 

[Fulvio Romano]

steal from the genere?http://www.sistemidiparcheggio.com/raddoppiatori-auto/?gclid=co2_oozhj6ycfuokfaodzcpp3ahttp://www.strabox.it/index_on.htmlhttp://www.strabox.it/index_on.htmlonly that they are not for lifting people, maybe we have to do some "lavoretto" to certify them, but maybe it costs you less than designing an ex novo

externally the structure would be closed with panels fixed on the 4 angles.
the purpose would be to bring maximum one person so
with a maximum capacity of 200 kg.

The pantograph boards (hydraulic) take them as a substitute or in germany (electrical).
But no one with features like what you need, definitely out of standard and, in my opinion, technically risky.
the risk, not technical, remains also using other systems that cannot be assimilated to an elevator.
to have no risks there must be a cabin within which the person is protected.
the point (3) of lightning will be the biggest problem you will have to solve, technically the solutions there are but must comply with the safety rules.
Do you have a sketch of what you want to get?
this summer I visited a former church that were turning into a museum, access to the upper floor for disabled people gave up doing so because of a situation similar to yours, would be too dangerous or too invasive on the rest of the structure.

Bye.

I'm afraid we'll have to change our way and find alternative solutions.

there is the possibility to directly load an attachment type pdf or jpg without having to
enter a url idirizzo?

Say hi.

found.

here is the pattern that would be necessary to realize.

Saluted.

feel how much the work of the notified body costs you (machine attached iv), you propose it to the customer and you see it whitening :biggrin::biggrin:

 

[MBT]

I know that when you make the quote by understanding design costs, testing, errors and certification.... you will see that maybe a perch to get up and down doesn't go so bad. .

 

[Blupower]

some photos to better clarify the context where to install
the lift:


if you have alternatives to propose, I accept them
Gladly.

Say hi.

Just to be pissed, the pantograph board you schematized doesn't move like that.
the standard geometry is the one that I attach to you, one side of the scissor remains firm, the other side flows.

Bye.

excuse, but the iv does not refer to machines that are born to be dangerous, like circular saws etc.?
or are you not referring to the dm?

I see it hard, but everything can be done. I think the ideal solution is the "lift" type, so a cabin is pulled by a cable. but I would still not recommend doing it ad hoc. Find someone who sells a suitable one, or sells solutions where the size of the cabin is customizable... but from them.

fulvio, particularly dangerous machines, Annex iv Machinery Directive 2006.42, paragraph 17:lifting equipment for people or people and things, with a vertical fall hazard greater than 3 meters.

Why not a cabin with four hydraulic pistons at four corners?

in practice an acensor with legs stretching :d :d

 

[maxopus]

Hydraulic drive machines according to norm need the local machine which in reality is a cabin that looks like a tall electrical picture more than 2 meters (not nice to see in a house).
have the advantage of initial economics and other disadvantages on consumption and management.
are also less accurate in the stop on the floor.
This company produces customized lifts of various types, perhaps it is worth contacting them.http://www.ascensorirerman.it/ascensori_su_misura.php

imaginative:biggrin: but unlikely I would say. considering that by closed those cylinders would be about 3.5mt long.. and then other reasons. .

Hello, :smile: I wondered whether the end of this discussion was the design of a pantograph forklift or the search for a producer of such a type of pedane.
