Working on blowing the cobwebs out of this thing and turning it into a useful piece of equipment.
Yesterday I started braking the boom down in order to get it moved over to the shop. Once we got it down to the boom heel, went to boom down into the transport cradle, and it wouldn't do it. I got boom up, and even when I push the boom control lever for boom down, it booms up.
Had this problem when I first got it, hung the main hook block off the boom heel and that was enough weight for boom down to work. Tried that yesterday and added two, 200lbs balls, no difference, still only booms up.
When I shut the crane down for the day; with the machine dead, I set the boom dog, and moved the boom control lever for boom down. Boom hoist payed out a little and stopped by the dog.
So what do the experts think? More weight tip on boom or some other issue? All other functions work great, but boom down has always been a little temperamental even with boom assembled.
Picture shows me hanging one of the 200lbs balls, nobody call OSHA, it wasn't as bad as it looks.
