Hot take: I think manual tag lines are safer than remote load positioning in tight spots
Was working a 15 ton Terex into a tight corner in Chicago last month, blocked in between a parking garage and a new high rise, and the remote system kept lagging on the swing. I ditched it, grabbed the tag line, and walked it in by hand with my spotter - took longer but zero near misses, and the foreman said I was crazy but it worked.
