Silly Question

[Brian S]

How much (approx) does a 3m or 3.5m length of 8" and 10" roundwood weigh, Softwood and Hardwood, green/part seasoned.

 

Liftable by one man, or 2?

 

As I said silly question

Have you done the cs41-45?

As you get given a graph which gives you the approx weight of green oak in different lengths and widths. Then you times it by the type of tree/wood and your'll get an average weight for the section.

 

Ill dig it out and email you a copy if u pm me with your email bud. Might help you out

3m of 8" wood is approximately 0.1m3. Multiply by the density of green wood, typically about 1 tonne per m3, so should be about 100kg. 3.5m would be 117kg. 3m of 10" wood is about 0.15 m3 so it's about 150kg. 3.5m of 10" would be 175kg.

 

Manual handling regs suggest no more than 25kg lift per man, about the weight of a standard bag of sand.

 

As wood gets seasoned it loses up to 40% of its weight in water. You can estimate from that how dry your wood is and what a length is likely to weigh.

 

It depends on species too. Lighter wood like dunkeld larch is around 0.85 tonne/m3, denser wood like oak is up to 1.06 tonnes/m3.

Thanks Dan, your a Gentleman , but I'm not an Arborist, or work in forestry, (work in Construction, must of been evil in a past life ) just looking to maybe process my own logs, (various reasons )

 

So looking to see what I can manhandle, judging by daltontrees post, not that much, specially at 62

Thank you good Sir

Lifting a log of this size in a dead lift would be liable to pop a b!$£%ck, but using a cant hook to roll it, and the principles of levers, you can shift big lumps about on your todd.

Thanks Dan

I see it all now, said the blind man

 

Going to have a play, interesting stuff, as they say, every days a school day

Don't think I'll be moving anything that big
