Customer Question
Good afternoon I need to move...
Good afternoon
I need to move a 16000 pounds CNC milling machine in the back of a building in NYC. It's an old building and the ground floor won't take the weight. We can't use a crane, prohibitively expensive.No space between buildings to go through the side either. The ground floor is 20 X 60 feet with 10 feet tall ceiling open all the way. There is a basement so re-inforcing the ground floor could be detrimental to the building. I was thinking of putting 2 parallel beam 70 feet long to go the length of the building and roll it through the building all the way to the back. A kind of bridge. Any thoughts or is that a crazy idea
Thank you for your help.

We intend to make a cement floor in the back of the building as well to support the machines. The bridge could be supported by that cement floor in tieback and the sidewalk in the front. We are also moving a CNC lathe weighting around 6000 pds. I can send a basic drawing of the building as well. If you have any other idea, they will be most welcomed.

If you think the beam idea is a possibility, what size beams ?
The building itself has 4 X 12 wood beams every 16 inches with wood floor. Even with hoist below in the basement supporting metal beams across to roll the machine above might be taking a chance. That's why i was thinking avoiding putting any load on the ground.

I apologize for the delay. I was traveling and just returned home.

The bridge idea is reasonable, but the beams would need to be extremely large to make that work.

Structural Engineer: StructuralEng, Consultant replied 1 year ago

I would do beams on the floor, similar to the bridge you're talking about, but lay them directly on the 4x12 joists. Then, in the basement, shore the joists directly below these rail beams.
