i'm sure you could hang 2000kg on this thing and ceiling would not colapse ... contrary to what most people in comentary thing ... and it would be a nice benchmark video - even if somehow catastrophic scenario unfolds ... success or fail - views guaranteed either way ;) great build, and a great tool to have !
@adrianbew. It is not impossible to hang a crane under a ceiling. This is often used when cranes of lower capacity are needed and the floorspace should be unblocked. But you are right that this way of installing a crane would require accurate measurements and proper statics of the ceiling and it his to be allowed to install a limited weight
Hanging a crane from threaded rods...... an accident waiting to happen. Anyone watching this, don't repeat the same thing. Risk a bit more money and put 6 poles.... and 2 beams across tho hold everything. This is just......too dangerous to be online for people to see.
@@themechTR yeah.....doesn't matter if it's 5000. Still unsafe. Take a look how 95% of companies have them setup (which are regularly inspected). Even pole cranes are safer than this.....
@@themechTR While i understand mounting w/ all thread was the easiest route and the rod is probably 5x the load rating of the crane, you have to take into account the dynamic loading and potential for metal fatique due to the dynamic forces acting on the all thread. Personally, i would fabricate a bracket to support the Ibeams from the bottom flange or put a few posts in as not only a fail safe but also to help brace the Ibeam and reduce any potential fatique on the all thread. Just my 2 cents, ive fabricated a few jib cranes and overhead lifts over the years. Best regards.
@@kurtsmith4657 You are right about dynamic forces. That is why the load I will lift will not exceed 500 kg. As you said, it would be most logical to place columns from the ground, but since I did not have enough space, I installed this system. Thanks.
Any failure of a rod or welded joint would be catastrophic, beam better bearing on upright girders bolted to floor not hung from ceiling .bolts need to be rated high tensile not threaded bar.
@@themechTR that is tensile capacity. You are relying on the strength of the threads of the nut and threaded rod. To improve safety, use more nuts. And you have another problem, sway (swinging) of the runway if carrying 500kg on the hoist and it swings, THE RODS WILL BEND SLIGHTLY and then shear (snap/break). To correct this issue, make a cage structure with pipe over the threaded rod so the hanging part acts as a whole, not individual parts. I am a civil/structural engineer.

@@themechTR Yeah, that was a really detailed video that I watched carefully. I was helping someone at the time and trying to talk them into building something like it for their workspace. Alas, they didn't go for it. It seems really useful for a lot of reasons.
@@Nicola_ColonnaI gave detailed information in the explanations, but I will write it here too. I fastened the joists with long screws and nuts in the attic. I used a thick steel plate and washer before the nut

@@WombleUK You're right. I couldn't take a video because the attic was dark. But think simple. There is a nut and bolt, and in between there is a washer and a backing plate. 🙂
