How many people to move a 45kg item by carrying?

@Scarfface a bad back is very difficult to resolve... Don't think you have to lift it alone because it makes you more of a man

@Terrance I think 25kg is the safe limit?

@Scarfface I thought it was around 20

@5thApprentice a big box, 500 meters up some stairs

@Scarfface Unless the person is pretty fit and strong then maybe two people.

@DxNxA you're a hunk

@Scarfface I WORKED ON A FARM AND I LOADED AND UNLOADED 50 KG BAGS ALL DAY

@Tracos its like 500 meters up stairs

So?
