if i was going to do this (i'm not) what i would do is get a couple of 2x4 cls, cut three lengths, (a jib, a mast, and a diagonal support) make the jib maximum say 1.5 x as long as the mast. (plus a small amount of jib sticking out to mount a pully) screw them together. cut triangles in 3/4 inch ply to match. glue, screw, about twenty coats of polyurethane varnish if its going to live outside. a couple of heavy duty pin style gate hinges attach it to the pole allow it to rotate around the post or lift off and away when not in use.
only problem will be you don't want it to swing on the hinge while you are using it, so grab a cabin hook while you are getting the field gate hinges to hook the crane to the post to counter the torque from pulling the rope.
the overall size will depend on the weight you are lifting and the clear span between the crane and the post fixings also. please at least understand moments of force before doing something like this. you know what torque is right?
