I believe that the end of the discussion is to find an optimal solution to the problem. They were told of crushes and cruel, and as far as some statements can be erroneous, they make the brain work, and this is good for the whole community:wink:

I hope it is not a reference to my sentence... It was just a question. cmq I decided to design one too, as soon as I have some time obviously. :tongue:
See you soon!

I guarantee that if those cylinders didn't have at least one snout, they would last very little, maybe the space of a day.
I've seen tratruding hydraulic cylinders with 100 mm order runs, because of a radial component.

in fact I wrote:

are not articulated where to connect to the structure of the medium[/B], and in fact they get all the side thrust that you, or who for you, apply to the truck

Maybe I explained it clearly
a snode generally there is and is placed on the "zampa" that leans on the ground.
but where the cylinder is fixed to the frame, I don't think there is a snout

Yes, in fact the snodes are only at one end of the cylinder.

comegle vYou are dbuilding: smile:

However, if you want synchronization, just enter proportional valves and sensors on the stems.
Who knows why hydraulic lifts on one floor, though, use only one central cylinder and four guides.

he... don't think that 4 proportionals and transducers on the stick cylinders. . .
or better, it depends on what your goal is. . .
If you come up in speed and you need a minimum error between the cylinders... You got your best.

Right, but for a hydraulic cylinder the push is not a problem. the race much more.
Perhaps, by the method of the carrucola you can also make sure that you pull instead of pushing? so you also avoid instability?

... and in fact if I don't remember badly "they make him pull" when he goes up (... we always talk about the elevator:smile ...

Bye-bye.

Maybe you didn't consider putting the snout on the leg when the cylinder isn't loaded doesn't stand.

Why?
explain yourself better... I don't understand, but it will be the fault of the late hour

far from me wanting to take your place of "disintegrator of the apparatus etc...)
If I put a snout at the foot of an auction, and the same does not have any other supports, it will be in unstable balance, don't you think?

Look, people who do my job, by profession or by dialect, there is a caterer! don't worry about this! as I have already written, really professional people (who are professionals) do not fear competition
But it seems to me that there is a mistake of communication. . .
a cylinder like that of the stabilizers of a truck is all added an oleodynamic cylinder
his body is rigidly fixed to the frame of the medium
inside runs a stem, guided in the worst case with two guide lines.
therefore can only slide and rotate on its axis
at the end of the stem, with some kind of snout, even spherical, we will be mounted a paw.
This can move as you like, to adapt to the ground, right?

I still don't understand where the unstable balance is. . .

That's what you say.
but trust that we put them on the tipping means and to save nothing unfolds. weld a nice picket under and hello

If the cylinder is fixed to the truck frame as you say, the application is the one described by you, I thought instead of an improvised lifting system (see photo) with cylinders positioned ad hoc on the ground.
two different systems.
Finally, the definition of "disintegrator..." was referring to my statements, I hope it was interpreted correctly.
Hi.

Well, it was about trucks. I kept on trucks.
for the lift, I have already given my negative opinion in adopting systems with more than one cylinder.. .

Hi.

Quiet
It's ironic (but not so much) in my description and I expect it to be ironic even when citing others... :finger:

 

[maxopus]

still with 'the pistons for a 4 money elevator?????? :biggrin:

guys just go to a site of any manufacturer to understand that:

1) an oleodynamic system has a lower initial cost but greater use and maintenance costs;
2) there are problems of encumbrance because you have to build by law a metal cabin that acts as a machine room (in case you pop up the hydraulic circuit it is right that there is protection);
3) there are problems of disposal for circuit oil;
4) an hydraulic lift will never have the stop accuracy on the floor of an electric elevator.

so if we want to give advice .... let go of the hydraulic systems and make quotes for an electrical system.
