How to simulate pivoting joints in FEA stress analysis

I'm designing a hook-like mechanism, where dog bone linkages are moved by a cylinder. Since the cylinders stroke is too long, I created a stop block (highlighted blue). 

I want to know how much stress is going to be applied and where to these dog bones when the cylinder keeps trying to push up. Ideally, this stop block, along with the mechanism, would be able to withstand this force from the cylinder (13.12 Tonnes).

I set it up as seen in the picture, replacing the cylinder model with a force being applied to the pin pushing up at 128663N. I put a pin constraint on every pin. When I ran this, it didn't turn out as expected.

How can I realistically simulate this to see if this stop block is effective for the setup?Capture1.JPGCapture2.JPGCapture3.JPGCapture4.JPG
