No what I could not understand was the cable puller, But after looking and looking at your picture a light came on

and correct me if I am wrong on your beam you have 2 "Pulleys" at the very top of the mass and from what I gather now, one of these pulleys is on a scissor, so this is how the weigh is brought up,
so you bring the mast to the correct height, with one cylinder. the one inside the mast, that's easy "telescopic" then you open the scissor, with another cylinder, and this pulls the cable and weight, and this is the cylinder that you release to drop the weight.
this triangular pivot is the way the cable is pulled, right? OK how do you stop the scissor from hitting - banging on the mast, did you simply adjust it so just before it its the mast it's at the end of the cylinder travel. cylinder bottoms out. and my next question How did you figure out how long to make the scissor so the cable would be pulled all the way up.
and it's just a nylon cable not a steel cable? thank you I to is the same as you" my normal design process, is to see what is out there, look at pictures and videos, see what features I think I need and what makes it work " I was not very good in school but If I see it I can build it, That's why I became an auto body technician.
One of the project I did last summer was to take and old 1970's 6 wheel dump truck that a buddy of mine had in his back yard, the truck was garbage but the rear box was decent,the guy gave it too me, he laugh when he heard my idea, now he said if I ever get rid of it he would be interested... I used the frame cut it behind the cab welded a hitch, installed a 10 hp gas motor on this hitch, with a hydraulic pump, and now voila I have a dump trailer to pull behind my tractor, I even left the rear axle on it, the cylinder was already in place.
Now if this snow can melt I will start working on this project.
Like I said once the snow melt's and that will not be until the start of May, that's a picture of my vehicle park on my concession road.
Thnx again for all the help.
