I have been asked to build a cart that can be pulled by a tugger. (A tugger is a small stand-up vehicle.) The cart has to have a ramp to push other wheeled carts up onto the tugger cart. The photo below gives an idea of what I have come up with.

The ramp on the left side is 30 inches from the hinge to the tip. The thick black line is a wire rope that is attached to the ramp 16 inches form the hinge. The incline angle of the ramp is 13 degrees. The ramp weighs 84 pounds. The lever attached to the middle of the cart shows that the lever is to the left when the ramp is in the lowered position and pulling the leaver to the right shows the ramp in the upright position. The length of the lever from the pivot to the wire rope connection point is 30 inches. The distance to the handle on the pulling lever is 42 inches from the pivot point to the handle center.

IF (and that's a big if) I have understood my research on this subject, I have to Class 2 levers. According to the math formulas I found the end result will require around 20 pounds of pulling force to lift the ramp.

Can someone please tell me if I came to the correct conclusions?

Thanks in advance and I apologize if I have asked this question in the wrong section.
