PSA: the old hand who said never boom up with a load on the hook was full of it
Back when I was running a 60 ton on a hospital job in Tulsa, an operator with about 30 seasons behind him pulled me aside and said flat out, you never boom up with weight on the hook, not even a little. I believed him for close to 4 years and would stop the drum, wait, then boom, which added maybe 15 minutes to every pick some afternoons. Last month we had a tight steel set where the ironworkers needed the beam lifted about 8 feet and pulled in over a column, and the only way to do it was to boom up slow while the load came toward us. My rigging guy said just ease it, that is what the controls are for, so I did, and it was smoother than stopping and starting ever was. Nothing tipped, no shock load, no bounce in the lines, and we set it in one motion instead of 4. Now I am wondering how much of what that guy taught me was just his old truck crane habits that do not apply to modern hydraulics and load charts. Any of you been told a hard and fast rule like that, then found out it depends on the machine and the chart? Would like to hear which ones were real and which were just folklore.
