Hydraulic Liftgate: Find Optimal Cylinder for 90° Rotation

[kore52]

TL;DR Summary

hydraulic requirements for liftgate actuators/cylinders

Hello everyone and thanks for any and all feedback!
I am looking for help with a hydraulic system for a liftgate conveyor I will be installing for a customer. The conveyor is 10" in length and 3' wide but the liftgate portion is only 7' long. The approx. weight of the 7' section 500lbs. My questions is what hydraulic cylinders would i need to rotate/lift the 7' section 90 degrees?

What hydraulic pressure will always be available.
The position of the pins at the hinges and cylinder ends will be critical.
The cylinder must be free to rotate slightly during operation.

Im thinking a 2 stage, 3hp 1500-3000psi set up

So you always have 3000 psi available ?

Where is the hinge pin relative to the frame and moving belt ?

I don’t have a pump picked yet but I can have whatever is needed. The hinges are in the side of the frame and I will mount the cylinder/s below and inside the frame rails of the conveyor

You must first specify the position of the hinge pin and the cylinder end pins.
Only then can you size the cylinder.
