How heavy do you reckon this would be??

[Al Cormack]

Had a look at a live Oak to fell the other day.

 

The main trunk is around 4ft in diameter and is like that from the ground upto around 20ft. It is a monster.

 

Thinking about using a crane, but not sure if it will reach or be able to pick this up, so how heavy would a piece of timber like that be?

[skyhuck]

6 to 8 ton I would guess.

6 to 8 ton I would guess.

 

That's what I was thinking:thumbup:

 

Had a trunk picked up a couple of weeks ago that was arond 3.5t, and definately less than half the size.

Not had much use with cranes, but could a crane pick that up from 45m away, or even half of that weight?

Very much depends on the size of the crane.

We hired a 50 ton crane the other day and it picked up 6t at 15m very happily but the hire man said that pick up weight is drastically reduced as you go out, then you are talking big cranes which equal serious big money.

 

The butt on the london plane that we picked up was around 8ft long and around 4ft diameter and that weighed in at around 4t. It was a really heavy bit of wood, so i reckon oak ain't far off that, and with cranes you can't get it wrong.

If your guestimate of the size is correct you're looking at 6.5 ton. so allowing for a wee bit of taper say 5.5-6ton.

It could weigh 7t and it will take a serious mobile crane to lift that at 45m - or even half of it

P.S. not got a chainsaw mill yet?

45 metres away ........u need a monster crane, used 1 to spanned the clyde...around 32 metres, he could only lift 1/2 ton at a time out that far..... good luck dont think the butt will pay for the hire though

[chris cnc]

could you not piece it into 1-ton chunks? then you could use the crane at full stretch maybe? of course it would take a little longer, but why do you have to move it all in one go?

 

not that i know anything about cranes.
