Lifting B'port series I R2E4 BOSS-9
I have my 'new' mill sitting just outside the milling room on a 4'
high trailer. I can have a friend with a boom lift pick it up and set it on its pad tomorrow. OR I can wait a week for a forklift to be free. Can I safely lift the whole machine using the access holes in the headstock casting? I know they're not made for the purpose, and wonder if the headstock bolts to the column will elongate or fail? (they look strong enough, but the whole machine is "cantilevered" off the column, unlike a ram-style machine) Anyone with experience moving this one? Thanks, LLoyd |

You could also use the week to review the electrical cab and sort out the phase converter or single phase rewiring issue so you're ready to go. |

: Is there some reason you can't lift it from the bottom skid with slings? I'd need a sling with a load fork to clear all the cabinets, etc. I don't have one, and he doesn't either. You could also use the week to review the electrical cab and sort out the phase converter or single phase rewiring issue so you're ready to go. I'm ready to plug it in as soon as it's moved. LLoyd |

Lloyd, interesting acquisition. Does it use paper tape for
instructions? Are the four bolts that hold the head, to the base, 5/8" in diameter? Do you have a manual? It should describe an acceptable lifting procedure. Can you call Hardinge to find out? They have some nice guys that could possibly help you. I just spoke to them on the phone yesterday about something else. Barring that, can you attach lifting ears to the two front bolts out of four, and then loop a chain so that it starts at one ear, then goes up to the hook, then goes underneath the neck of the mill, then up again and to the same hook, and then down to the other lifting ear? That would seem to leave it in a fairly balanced and safe position. Maybe use real bolts instead of front bolts depending on weight distribution. If you have an adjustable sling, like one the pictured on McMaster page 1456, you can do that very easily. I have one and it is very versatile. i |

: Lloyd, interesting acquisition. Does it use paper tape for instructions? It can, but it can load up from a text file. It'll go up to 9600 baud, which sounds like creeping by today's standards, but fast enough for a g-code/m-code block. Are the four bolts that hold the head, to the base, 5/8" in diameter? I didn't measure them, but seem to recall they're 1/2". Hmmmmm.... Do you have a manual? It should describe an acceptable lifting procedure. Only an operator's manual. Nothing technical in there. Barring that, can you attach lifting ears to the two front bolts out of four, and then loop a chain so that it starts at one ear, then goes up to the hook, then goes underneath the neck of the mill, then up again and to the same hook, and then down to the other lifting ear? Hmmmm... that probably wouldn't work if the bolts are 1/2", but you just gave me an idea. Now I've got to find that roll of 8" wide webbing.... If you have an adjustable sling, like one the pictured on McMaster page 1456, you can do that very easily. I have one and it is very versatile. I have several 5/8" load binder chains that will suffice for this small a load. LLoyd |

No, but I can't imagine any bolt bigger than 1/4" grade 3 that would not have a tensile strength several times the weight of any BP mill, even multiplied by the cantilever. If you have 4 of them, I'd say it's a great bet. |

Of course you're right, but I have this thing about "safety factor" with overhead lifting (and when it's coming out of my pocket if it crashes G). LLoyd |

LLoyd Key points: - It's not "overhead lifting", it is simple lifting. - Lift it a couple inches, then pull the trailer out from under it, then lower it to an inch or two above the ground before any horizontal movement. |

: - It's not "overhead lifting", it is simple lifting. - Lift it a couple inches, then pull the trailer out from under it, then lower it to an inch or two above the ground before any horizontal movement. I agree with your second point -- that was the plan. But any time the majority of the load is above head-high, I call that "overhead lifting". That may be only semantics, but in this case, all but about 500lb of the machine will be neck-high by the time we can pull the trailer out. I got the info I needed (for certain), and the head's plumbing access drafts are a legitimate place to lift. That solves a whole bunch. LLoyd |

in . 3.70: I got the info I needed (for certain), and the head's plumbing access drafts are a legitimate place to lift. That solves a whole bunch. Oh... Thanks Iggy, for reminding me that the Hardinge guys are "good fellas". They hooked me up with one of their (by their words) "old- timers" who had a lot of experience moving BOSS machines. He chuckled a bit, then said that they lift the entire head off (about 1000lb of the 3500) with just three 1/4-20 bolts under the motor cap. He also said that the access drafts "were the standard sling point" for that machine, and much preferrable to getting it up to pallet height with Johnson Bars. LLoyd |

Thanks, LLoyd Moved a Boss9 R2E4 several times and a Boss 5 once. Both series ones. Leave the head attached. Sling basket through the mentioned holes in the head casting on a hook. It'll pitch forward a little, so be ready to pucker a bit. I built a skid with 4x4's and 3/4" ply on top and bottom. The lumber is dead centered under the leveling holes in the base. I lower the machine onto the skid & lag it down. Use a fork truck from there. Orient the skid to lift from the non-cabinet side. I'd wait for the fork truck. Good luck! -- John L.

It's moved, on its 'home' slab, and will get hooked up in the next five or six days, as other work permits. Thanks for all the help, folks. THIS machine is my biggest, so far. It clears the ceiling by about 3" G. LLoyd |

My forklift can only lift 5k, so I made skates and called a tow truck. Speaking of height clearance on the r2e4, at it's first home with me, it was sandwiched between the floor joists of my walk-in basement... -- John L. Weatherly please remove XXXs to reply via email |

: (Lloyd, ask the seller for a copy of the manual, possibly for a fee) All he had was the "operator's manual", which he gave me. It's basically a discussion of what keys do what, and how to power up the machine. There's nothing in there about hookup, types of lubricants, etc. But I found a really nice guy (actually two of 'em) on CNCzone. One will copy his manuals as time permits, and email JPGs of the pages. The other one will do a full paper copy of all seven manuals, and ship them to me for about $150 (which isn't a bad deal, considering the volume of paper). LLoyd |

@en-nntp-08.dc1.easynews.com: http://versitechproducts.com/images/...26a_S1R2E4.gif Wes, that'd be it. You have to keep the scale in mind, though. The keyboard is about 3" above my head, and I'm 6' tall. LLoyd |
