Lifting Equipment - Uneven lift
Lifting Equipment - Uneven lift
(OP)
Afternoon,
I have a 3 leg lifting device which will lift a component in two states. Open state is a straight foward lift. The component could also carry a unit on one side of it, which would affect the lift. So my 3 leg lifter has an offset lifting hole to cater for the offset weight. My question is what function can I use in NX 7.5 to determine where the C of G would be when lifted from each lifting point? I've tried a few things but don't have a license for it.
Thanks in advance

To the Toolmaker, your nice little cartoon drawing of your glass looks cool, but your solid model sucks. Do you want me to fix it, or are you going to take all week to get it back to me so I can get some work done?

Yes, you can use NX to find the CG.
In the model:
analysis -> measure bodies -> asoociative (toggle on) -> pick the bodies in the assembly that you need for the lift
The CG will show as a point in the assembly model. In very large assemblies it may be hard to find. Naturally look close to where you think the CG will be.
There will be a Body measurement feature in you Part Navigator. By highlighting that you may find the point easier.

Or am I talking about something that doesn't exist?!?!?!

Does that make sense?

Now add your additional Component(s) and then go back and edit the 'Body Measurement' feature, that you will find in the Part Naviagtor' and while in the Edit dialog, select the newly added Component(s) which will add them to the measurement feature. After selecting OK the CG Point will move to it's new location. Now all that you have to do is move the arrangement of cables so that the main lifting cabled is again aligned with the location of the Point and your load will still be stable when lifted.
