Hot take: I think pre-lifting your load is safer than floating it off the ground
I've been running cranes for 15 years now and I see most guys around here floating the load an inch off the ground before a full lift. Back in 2012 at a job in Portland, I watched a 4-ton steel beam swing loose because the operator tried to float it on uneven dirt. The crane tipped just enough to scare us all. I switched to a slow, controlled pre-lift to clear the ground by 6 inches, hold for 2 seconds, then go. Never dropped a load since. Has anyone else tried this on an actual job site, or is floating still the standard for you?
