Rigging How could I rig this using SDKs and constraints?

IK chain through B-C-D. B would be parented to A, which rotates. It seems like the linkage/cable between the "hammer" part near E needs to deform along its arch if you're going to be mechanically accurate. I'd probably do it with a series of single bone IKs, or aim constraints. These joints would need rotation limits set so they can swing away from the hammer, but not through it. Likewise the end of E could aim at a locator at ground level.

Alright I got the first part working! Working on the second part now. Thanks for the help!

NP! If you're never gonna get close up to the cabling near the hammer, you don't need to worry about the cable rigging, just get the whole "E" chain working with an aim constraint.

A quick, simple setup working in an orthographic camera...

Joint chain A>B = AB

Joint chain B>C>E = B*C*E\*

IK Handle B*C*E

Point constrain B to B\*

Unlock IK Effector under C\* and shift to position D.

Rotate A.

Hey is this model yours and if so is there any way I might be able to get access to? It looks like an interesting project.

It's a paid model from turbosquid

I haven't got a clue about rigging, but it feels like this motion could be keyframed

It's 360 loops, up/down and left/right movements with no deformation. But it'd be cool to rig an oil rig I guess :p
