Can anyone explain what part of the hydraulic system makes that loud hissing sound when the elevator is about to stop or when it is going down? Our elevator does the same exact sounds and I always wondering!
@@Simos805engineering has progressed significantly over the years. Laminar flow with bigger hydraulic lines sometimes has something to do with it. Also mufflers as well as oil properties such as viscosity and also what the oil itself is actually made out of, are also factors
Interesting hydraulic hole-less elevator, I've seen an elevator similar to this one expect roped. Never seen a power unit like this one, I'm assuming the valve are top of the housing with a submerged pump in the oil tank. Runs on 3 phase power? 230,440 or more.
5:30 It May seem strange but the pump motor is usually submerged in the oil with the operating valves on top of the tank. It’s common these days to have the hydraulic cylinder in the side of the shaft, and often with a rope connection to the car. That saves having a deep bore hole underneath to accommodate it. There’s lots of problems creating that borehole in a crowded town or city.
Looks like a pumping unit for a limited use limited access elevator max speed 30 fpm and that flexible hose to replaced or pressure tested every 6 years unless there is an over speed valve.
So you don't have to watch the video Lucky Bulb replied to you, I will explain it for you. On the side of the door frame in the shaft, there is a lever with a wheel on the end. If you push on that, the door unlocks, and you can open it. On the side of the Elevator cab, there is a bar that pops in and out that pushed on that lever.
So I guess it's just a box mounted on what's basically an electric jack. Rather interesting. This one has internal doors which is odd for these kinds of elevators, but the fact that the outer doors swing open is already bizarre and foreign for Americans like myself.
Nice video, thanks for posting!
I was so happy to see my first hydraulic elevator motor, it was the best day of my life
They’re quite boring things to watch, even when they’re running.
Nice Bauer elevator, good Video
nice elevator!
Thanks :)

Not many machine rooms have a hole in it:)
Good vid!
The first
How do you route out ropes in conventional machine rooms? ;-D
Thank you so much for sharing. I really appreciate this comprehensive look inside. :-D

Awesome video!
N.E.A. Elevators Thanks ;)
Awesome video. Been trying to see how the hydraulic elevators work vs rope
+Daniel Rivera Much Thanks :)
most hydraulic lifts have ropes, you can use a smaller ram 2 to 1
Daniel Rive
Tony Baines
What kind of liquid does a hydraulic elevator use? Also if an elevator had a rope, what would be the ropes purpose?
Nice video
Great video. I was surprised to see the rams are on the sides. Makes sense, I guess I just assumed it would be in the center.
It's just like lifting weights with your muscle power (manpower) 💪
Is the controller relay logic?
I watch this video in a long time

It's the valve slowing the flow of the oil and when going down it uses gravity so it's the sound of oil rushing into the tank
@@QEElevators And how they managed to make it silent in newer machines?
@@Simos805 Most new ones aren't, I've never seen a silent new one it might be the type of piping

Wow good chanel
Cool
That's got better hoistway lighting than anything in the metro st. Louis mo. Area. I'm lucky if the cartop light is bright.
vielen Dank.
I bet that cut at the beginning was the kid saying why does it smell like hydro fluid?
I bet you have been commenting too much.
very nice interesting video
Thanks :)
I Always find hydraulic elevators interesting..

This is an ALGI elevator, with telescopic cylinder.
It runs on 3 phase power, 400V ;)

400v 3P at 50 Hertz. Probably at least 30 hp

Didn't realize hydraulic elevators were so slow. Cable ones are a way better design. Counterweights make all the difference.
Tom Smith and noizy!!
Cable elevators are also significantly more expensive.
I dont understand how that little motor box can lift such an immense elevator car
+francobobfred the same, like you are able to lift a 2ton car just with your hands and a small hydraulic hoist
That's why hydraulics are used! They are great for high torque applications.
How far is the car from that hole in the motor room?
Is it low on oil?
No. You have been commenting on this video WAY too much.
OHH NO ITS MODERNIZED!
R.I.P.
this Elevator is in Germany ?
This is in Germany, near Siegen town ;)
How did you get back there and will you bring ma with you plzz
How do you unlock the hoistway doors from inside the shaft?

That is cool
Seems a bit low on oil
wery nice elevator

Once at a hotel the people who worked at the hotel or it was the manager who let me do it and for the first time I saw that elevator motor

i have a hydraylic elevator who is modernized by emgi lift AE
Hi
1:09 oh my ears 🤕
Only 20 bar.
hallo
it gives me nightmare
the Elektric Motor inside the oil tank..normali 3 to 5 HP elektric Motor.
So I guess it's just a box mounted on what's basically an electric jack.

It was a bigger hydraulic elevator motor than this one, the one I got to see was bigger!
