I have a T-350 that I am having some issues with the boom dropping and was hoping some of you folks could help me. I have all the manuals for it and can't seem to come up with any real fix, my crane has the sprag clutch setup and everything is clean and oil free. When I boom up to the stops and boom down, it's nice, smooth and predictable, if I stop and try to finess it down it runs and is very jerky like the brake is either on or off. It has the six part gantry hoist line and is very smooth when booming up, swinging and hoisting, just booming down is when I have issues. Those are the symptoms, if anyone could help I would be forever in your debt, thank you and have a good day.
