Calculate Force Compression of Crane with Hoisting Slink

[Herbid]

Actually it is a simple one, but the point of view of the force acting in pic attach of some people are different.

The adding weight of hoisting slink blue and the pulley is neglected.

I think the crane with hoisting slink (and pulley in first pic) creating more compression force into hinge A than the one without.

Is my analysis correct?

On problems like these I was told to make a free-body diagram.

Simplify the problem by imagining the lifting boom is vertical and draw a free-body diagram or just imagine it for the two diagrams. In the first case you have two forces and in the second case you have three forces.
