Remember to ask matey about crane sizing please. 


 

It been a while since I had my short lived affair with the crane truck, but iirc, for HIAB cranes at least, a 13tm (for example) is exactly that, rated to lift 13 ton at a meter from the center of the crane, quick bit of mental arithmetic and you can work out what it’ll lift at any given meter

13(ton) divided into 2 (meters) = 6,5 ton at 2meters for example 

 

I think it’s always calculated fully boomed out and horizontal 

 

My lifting chart of a 13tm crane started  

at 5200kg @ 2,5m as that was the first available lifting point when horizontal - I don’t know when or to who but apparently this makes it a 5,2ton crane for those unknown people/scenarios - I guess on that line a “20 ton crane” might therefore be 50tm ? 
 

if calculating a job, knowing the tm and max reach will help you know what it’ll lift and at what distance

Oh interesting, they came to you. Couldnt be easier. Do you have a decent chunk of land to let it pile up like that? 

3.5 hectares so plenty of room

A rood is an ancient measure of land Stubs.

 

He’s being ageist.

Me being an old cnut I am somewhat embarrassed not to have known that . However at the risk of embarrassing myself further I still am not sure of the context , even though I now know what a rood is now .
