I found this Wolffkran. It's model 1250 B. It has capacity of lifting 60 tons.

Wolffkran 1250 B

Yet, i can't find hight of crane. It seems it can be composed of elements to desired hight.

In 2007 this project was more like a vision, and for a 1600m tall tower. Such a big project needs time. But now they're working on the first floors over ground

They can mix it in some floors and pump from there, saving lot of effort to pump all concrete from ground. Also maybe they don't use pumps, they rise containers with concrete that they pour where needed.

Great to see another crane, raised very soon!

You can tell a building is going to be fantastic when people get this excited just about seeing cranes go up!

they'll definitely use pumps. Lifting up concrete in a container up to 500m or more doesn't really work . would take way too long.

Or they just construct the spire out of steel


... I guess wind readings on the half build structure would help to decide what to do with the top (dumper or no dumper) and with what material to do it.

The density of the rebar is amazing ... logical, when you think that these ground levels of the tower will have to withstand the weight of around 167 floors above them

I thought I would post this video which was probably taken before the 2 red cranes were installed. Ignore the date in the video.
