how heavy might this oak beam be ?


Any ideas roughly how heavy (Kilo or hundredweight) an oak beam 12 inch x 12 inch x 10 ft would be ? Also then how many people should be used to lift it and carry it by hand safely ? Steve

The following website gives the weight of seasoned dry oak in kg per cubic metre.

Should be easy to work out the total weight of your beam from that, and in my opinion each adult should be safe to carry up to 25kg each providing they are physically fit, but I would half that for lifting, putting down and any back twisting manoeuvres.

Google for oak + weight +cuft gets:
"The weight of dry, seasoned Oak depends on it's type (English Oak, Red Oak Cork Oak etc), but will be in the range of 590 to 930 kg/cubic metre. This is an enormous variation, but there are lots of varieties. If you know the specific type of Oak you are working with, the answer can be more precise."
Based on that it should weigh between 165 & 260kg which suggests 2-4 people with the lift being carried out in stages at alternate ends with ironmen* to support between lifts.
Try to lift one end yourself and you'll know whether it is a 2 or 4 man lift.
*or is it strongboys, y'know, the heavy duty, metal, adjustable height support frames

Many thanks for the info, very important point about twisting manoeuvres. Not the sort of shape one can lift with legs doing the lifting, means bending over to hold it in middle etc, even for guys at the ends. Not good at all, certainly for just two.

Much more difficult if the lift has to be above shoulder height, then extreme care is needed.
