Are you sure? Let me show, please, diesel power pack on the deck of ZSL crane with white cab at the construction of Shanghai Tower (see second photo in my previous post). Crane on ST is very similar to the one to be erected here.

And why you wrote "huge stuff must be drived by diesel"? Please, read the table at http://www.favellefavco.com/main-tow...el-luffing.php
You can see here huge Favco cranes (from 1050D to 1680D) powered by diesel (series M) as well as electric powered ones (series MK). So, if huge Favco can be powered by electric, why ZSL can not?

Looks scary to me too. Presumably there will be some glass fences or barriers up to prevent people from falling to their death every so often.

barriers and fences are almost never shown on renders.

Sorry for my ignorance..But I can read the Chinese on the instruction manual,it says 630HP diesel..

Is it possible that the diesel is integrated inside one of the base parts? On the picture below you can clearly see something that looks like exhaust pipes. the only question is where is the engine

Yes, it's possible. I also did catch sight of something like exhaust pipes.
And I sent letter to ZS company with question about power supply of mentioned above cranes. I will iform you all about answer.

I think diesel can be ingrated inside deck.

Those two silver colored pipes do look like mufflers.

I did find some information about ZSL2700 employed at ST construction:
http://en.zs-nj.com/newEbiz1/EbizPor...6e1402b3504c32

Quote:
Shanghai Central Mansion is constructed by Shanghai Construction Co. This project was adopted ZSL2700 tower crane and was constructed successfully. ZSL2700 tower crane belongs to the super-huge internal luffing tower crane in the construction of high-rise steel structure. It’s driven by diesel engine and the max. working radius is 60m, and its hoisting weight is 100t within the radius of 27m, max. height can reach to 632m and the hoisting speed is 110m/min, which is in a leading position in our country for the hoisting performance and
Thus it looks that diesel engine is really hidden inside the massive red deck. If it is, then we "discovered" essencial difference between Favco and ZS cranes. I don't remember Favelle Favco cranes with diesel power pack integrated into deck.

And there is question to guys from Shenzhen.
Is it possible to obtain photos of deck internal parts of ZSL2700 crane?

Hi Bohdan.. I think you'll find they drop the power pack.. (the engine) and tank in where the counterweights go.. If you look at the FAVS in Shanghai, and at this one.. you see around 8-10 counterweights that look like 10-tonne ones.. On the Chinese copy crane, they drop the power pack in at the front before 5 counterweights behind.On the FAVS, the engine sits behind the jib hoist cable box. On the 2700 there is also a bit of engine next to the jib hoist cable.

Hi abc

Yes, there is less counterweight panels number than on Favco cranes. But have they get large engine (we see approximate size of powerpack on Favco cranes) into so narrow place front counterweights? I suppose there is only some part of power pack, maybe only diesel... Fuel and hydraulic oil tanks, hydro-pumps and other powerpack details are probably distributed over all or half internal size of deck. Such way for engine placing is very similar to the one on large crawler cranes (most models of Demags CC and Liebherrs LR cranes).

Does China plan on constructing a taller skyscraper soon or is this the end of the road for the foreseeable future in term of height for China?

There's the 777 Tower proposed in Qingdao which is supposedly going to be at least 700m tall and a tower in Wuhan proposed to be 707m tall. I await the day China proposes something taller than Burj Khalifa (possibly using the lucky numbers, 888 meters?). I don't know how likely either of those proposals are though.

That depends on the ambition of Chinese developers.....Chances are there will be competition within China to build an even taller tower. So yeah, they will plan for something taller in China just like any other country.

Yep, everything is on the deck and in counterweight bay.. I think the tank is on the deck... as you can see in this photo of the 2700 in Shanghai, there is nothing under the deck. Hope the weather isn't too cold for you. Bloody hot here.

Yes, there is nothing under deck. But I'm talking about place inside the rotating deck...
In Cityrain photo you can see on the deck only two winches and something not very big near the jib winch. I have doubt that it is engine.

In anyway we need more detailed photos of ZSL2700...

I am rather enjoying this height competition that the Arabs and Chinese are involved in (unfortunately, it seems the Chinese are only playing for #3 right now).

Concrete also provides a lot of compressive strength while steel provides tensile strength. A tall building needs both to withstand various static and dynamic loads.
