Weight of a stem...

[Ty Korrigan]

Hello,

I've an old client who has asked me to remove a fir of around 45m height.

It sits at the bottom of a steep slope on the bank of a lake.

It will need to be topped out before felling due to proximity of electric lines.

The stem has a 100cm DBH and does not narrow much for 20m.

My client would like to recover the stem for possible future milling.

Question is...

How much will this stem weigh?

 

I might have access to a 20t 360 with which to drag it up the slope.

 

Regards

Ty

If it's say a 75cm average perfect cylinder than itll be a touch under 9m3, times 550 (kg/m2 for fresh douglas) makes about 5t, max

To clarify you are asking for the weight of a 1m diameter x 20m long log in fir flavour? How much are you taking off the top otherwise?

Wow thats going to be an epic tree and an interesting job be sure to get photos/videos.

I hate those skinny taper tall ones always give me disco legs, prefer our fat squat trees.

What lengths of timber does your client wants to the stem milled to ,surely not 20 metres.so why not cross cut off bank and remove in sections that will fit the mill.then stem weight will be irrelevant and a 20 ton digger will handle logs like Match sticks. Also distance to power lines will dictate final felling length

A 20m length of diameter 1m will have a volume of 15.7m3 and at a density of 0.55T/m3 will weigh 8.6 tonnes
