OK So here is something i have not seen or heard of anyone looking for. I need a little bit more reach with the boom on the m816 so I was thinking of building a lib for the end of the boom that would pin on. I understand that it would lower the lifting cab but I don't need weight just height and reach for a few jobs I have done. I was thinking a ladder type frame with 4 mounting points and a cable on the top running to a mounting point on the back of the boom with a stiff leg in the middle with a reverse turn buckle to put upward tension on the jib. I was thinking maybe 8 to 10 feet max on the length and it would only be set for single line pull so there is more then enough cable on the drum to reach the ground at full height. Has anyone done this before or seen anything on an 816? I know they use them on regular cranes but nothing commercial will fit, I tried. Any ideas or tips.
