any tower crane bods in da house
There is a construction site not far from me and they have a tower crane , now over the last three days when there wont have been anyone on site
except maybe security, i have noticed the crane keeps moving. Now my question is do they move to keep th eboom in line with the wind to stop the thing
been battered from the side a bit like a ship at sea or have i consumed far to much and need to stop drinking.

Tower cranes are never "locked up" to allow them to weather cock in the wind

all perfectly normal. it is called weather vaneing and when out of service the crane must be allowed to rotate with the wind. if it were locked in one
position the wind might put undue loads on to the mast and bring the crane down.

I remember two guys being rescued from the bucket of a tower crane in Liverpool, the 70s.
They had climbed up for a dare and slid down the cable into the bucket and couldn't get back. Fell asleep in the bucket and nearly bricked it
when they woke up and realised where they were. 
Tell them about the bent treacle edges!

Technical question - does weather-vaning constitue over-sailing if the crane's not in use - anybody?
BTW rock-climbing mate at College climbed a tower crane in Coventry one night and hung a Rag banner
from the furthest end of the jib.
Now that takes some balls!
Cheers, Pewe
