ralla di rotazione

[Dutch Mauro]

Is it better to use a radish with external or internal toothing?

 

[MBT]

I think I better not use the ralla....

Have you seen the link I posted before??

for such a thing the ralla would only work in two points practically, you should balance the weight to make it work as it should, they are done for an axial load. . .
I would follow the link posted by mbt

on the internet I found this crane that consists of a ralla + a counterweight.

thanks in advance:biggrin:

or would it be better to use a bearing x avoid counterweight? ?

 

[lollo3d]

At this point I think you've been forced to use the raddle. .
What does "or would it be better to use a bearing x avoid the counterweight?" explained better.. .
counterweight serves to balance the effort on the spheres of the saddle

 

[stevie]

is it your case?
If the rotation you do manually use a smooth radish, I recommend not to weld on anything. the fixing you do it using the comfortable luminaires provided on the outer and internal ring.

What are the lights??? ? ? ?

gasp, I lost myself, I no longer understand who wrote the question
But if the crane doesn't make 180°, why do you need a raddle? How are all the flag cranes made?
