I am a tower crane operator of 9 years and theres no chance anything could go wrong even if the crane was stuck in the middle of a wind tunnel/vortex. The worst thing that could happen is the main power cable through the slewing ring could twist so much it would snap. That would all happen inside the tower not causing any risk to the buildings or the general public. Also most newly built machines have a splitter in the slew ring so the crane can spin around as many times as it would like to.

Hello.
,
First off, every tower crane I have worked on has a slip ring assembly that allows it to go round. Second, yes there is indeed a brake, The motor controller provides AC to run the motors but DC to lock one in place, try it sometime with an AC motor, as little as 6VDC can lock one in place solid, add to this the gearing of the drive and you have it.
In order to have it spin free the drive is disconnected, what keeps it in place is again, a DC operated clutch.

Chuck Norris stole a crane and took it for a joy ride lol

It would actually be far mor dangerous if the carrior locking pin or carrior brake were in place thus side loading the crane and potentially causing it to fail and crash down.

i dunno bout you guys but i'd rather see it spinning than bending haha

They should hoop up a generator to that crane and it could make money when it is not being used. lol

if the operator had left the jib at a lower angle it would not have spun like that

they couldn't lower it any more than that because of the proximity to the building on the right
