Self erecting tower cranes are working all over the place. There are about 50 of them working in NSW at the moment. The main purpose of this article is why there is a different ticket for the self erecting tower crane (CS) and tower crane (CT)
The CS drives like a normal tower crane (they can also be fitted with a cabin, but never are, it would be stupid to do so) but are pretty much always driven via remote control.
They have the same features- 4 part / 2 part hoist, cut out, free slew, slew brake etc.
They are small in size with a max hook height of about 23 meters when set up on ground level (they can be set up above ground and are often set up on suspended slabs with back propping)
As they are small in size they are quite reactive and easy to operate, they have much less hoist and trolley speed than most tower cranes again making them quite easy to operate
So why the different high risk work license?
Good question, back around 2006 WorkCover introduced the self erecting tower crane tower crane ticket, abbreviated on the high risk license as CS. There was a 12 month transition period where people with a tower crane high risk licence (CT) could continue to operate a self erecting tower crane but after that period they would need the CS license.
But why the need for a separate ticket?
Yeah I'm not sure of the logic behind it by WorkCover.
They added the CS to their range of licences but not to long after got rid of the excavator, bobcat, backhoe, dragline and a few other high risk license classes.
Hope that explains everything for you :)
