When drum 3/4 lever is pulled back to farthest position, after a few seconds it goes into a high idle. When booming down is it also supposed to kick into high idle or is there a safety feature in place? Current 14000 I’m working on booms down slower than boom up while both are at 100% shown on screen.

The Manitowoc 14000 goes into high idle when the drum 3/4 lever is pulled back to provide full engine power for hoisting or lowering operations. Yes, there is a safety feature affecting booming down speed; the boom can boom down even if the maximum boom up limit is opened, but the boom up function is restricted if a limit switch is triggered. This protects the crane from exceeding safe boom angles.
