Shooting

[Guido]

Hello everyone,

I hope I'm not wrong.

I have the need to "win a machine" on the ground by means of chains tensioned with special crik.

it is not possible to create a dedicated foundation because the machine will remain in operation for a period such as not to justify its design and construction.
I do not have many data available, if not the weight of the machinery of about 12000kg.
the machine has 4 feet (as if it were a table) that will be rested on a concrete floor. everything is self-supporting, but it must be prevented from "adccidental" movements, therefore it was thought to bind everything with chains that push everything down, in correspondence of the 4 supports.

Unfortunately, I do not know the extent of a potential force that can make everything move.
I would need to know if there are fast fixing systems such as fischer that can withstand "axial" extraction forces of the order of 2000/3000 kg or more, the doubt is that they can parade, or similar systems.

Thank you.

I have not understood...the dedicated foundation should not serve to avoid moving, rather to avoid deformations or deceasing in the points of support. By the way, if you put such a counterfeit, it increases the load even more on the loft. Are you sure that's enough?
12t concentrated in four small areas of support give a considerable pressure, I do not think that a standard workshop floor is designed to hold such load.

However, a maximum line should be put at 45° anchors to the ground with wallpapers (chemicals or mechanical). the counter-venting divides it so as to return to the maximum load endured by each background.

like side forces...boh? What car is it? If it is a lathe, maybe you can also not anchor it, if it is a flying shears from the rolling mill... feel the vibrations two kilometers away.. .

I agree with lightning.
I'd like to see a box of this. Is that possible?
Hi.

 

[MBT]

I agree with both of you. .
about the forces.. depends! if you consider what the machine itself can generate, it is said by lightning.
If you mean "external" forces, then you have to consider strange phenomena like earthquakes, wind or similar

as soon as I have 5 minutes I make a drawing....

but more than anything I wanted to know if on the market are mechanical or chemical fischers able to hold axial tractions (forces that parade them away... )
of the order of 2000/3000 kg on normal industrial flooring.

to explain better, a fischer holding a 3000 kg chandelier:biggrin: (considering the ceiling/solar in c.a.)

Thank you.

we fixed a support for mounting the oscillating mass of a 4200 kg weight cannon using hl type chemical anchor. ti hit-re 500 with has (I'm not sure of this acronym, I have a photocopy and it reads badly, tomorrow I can see in the office).

 

[gerod]

there are different types of anchors.
generally the problem is that, in the case of cls, what yields is the cls not the anchor.
cases are:
- the anchor shows off
- the cls breaks and breaks with the anchor
- the anchor breaks.

if you go to the website hilti or other similar you find a lot of technical material (after registration) and also the program for calculation (I must say that it is done well).
