And yes, the Tower cranes with the angled jibs are called Luffing cranes.

Something interesting that I read somewhere- apparently the demand for cranes is so great that unscrupulous chinese counterfeiters have gotten in on the act, supplying counterfeit parts and even entire counterfeit cranes! Of course, they look just like the real thing, but they look and perform like shit, most likely being accidents waiting to happen.

I wonder if the crane collapse in NYC was in anyway related to counterfeit cranes use? I could not find the source of the crane involed in the collapse.

There are many reasons relating to any tower crane accidents.

For example : (1) crane counterfeit parts
(2) foundation
(3) anchor bolts for foundation and tie in.
(4) dismanlte and erect tower crane.
(5) engineering stuff relating to tower crane should be done by
qualified engineer, but many tower crane contractors who
are not qualified engineer practice engineering relating to
tower crane by themselves in order to reduce cost as much
as they can.
(6) overload
........etc.

Tangsun's pretty much on the money here.
I have heard of accidents caused by people attempting things for which they were NOT qualified- designing foundations, planning operations, etc. They think they will save a buck or two, until something like this happens.
And erection, dismantling, and climbing are prime times for mishaps, as the crane is at its most vulnerable at those times.
Proper inspection of any crane is a must. Daily inspections of critical components, and fastidious maintenance is vital. Cranes recieve a lot of stress doing their jobs, and care must be taken to be sure that this does not lead to unsafe conditions- cracks due to metal fatigue being one example. Cracks are inevitable, and because of this, they must be treated when found, and between jobs, the crane must be thoroughly examined for any.

I think of a massive Tower crane as almost akin to a human athlete- they're incredibly tough and capable of awesome performance. However they need a high standard of care to stay that way. The consequences of neglect, carelessness, or negligence are unacceptably high.

For those in the know about cranes, I was wondering...

Who is the world's largest crane manufacturer?

Liebherr? Terex? Manitowoc?

Also, anyone know if Liebherr is private or a publicly traded company?

AltinD · #66 Posted **Apr 8, 2008, 4:23 PM**

^^ The French company POTAIN is big too.

Yep. We're getting a number of Potain models in Calgary now, including so far one but possibly as many as 3 in the near future on the Bow. Supposedly one of them (likely the one thats up already) is the largest Potain model available in terms of lift capacity.

As for Liebherr, they appear to be family held still, the parent company is based in Germany.

NeiNastran · #68 Posted **May 23, 2008, 3:26 PM**

Any good crane companies to invest in?

Amanita · #69 Posted **Jun 4, 2008, 9:34 PM**

Any of the major crane builders, really- Wolff, Kroll, Potain, Liebherr, Terex- high quality crane builders and the demand for their work is high. Really high.

Potain · #70 Posted **Jun 5, 2008, 11:52 AM**

Potain is now part of Manitowoc.

The MR605B at the Bow is currently Potain's largest luffing boomed crane but it is not their largest crane.

in calgary?

Potain · #72 Posted **Jun 6, 2008, 12:08 AM**

Yes, in Calgary.

Here is an example of a large Potain Hammerhead tower crane.

1ajs · #73 Posted **Jun 7, 2008, 4:14 AM**

is that chernoble?

CanadianCentaur · #74 Posted **Jun 9, 2008, 9:20 PM**

Yes, that's Chernobyl. Easy to spot because of that white chimney and the fat concrete shielding being built because radiation levels are still dangerously high inside of what was left of the reactor.

Potain · #75 Posted **Jun 12, 2008, 10:55 AM**

Yes, and in addition, the crane was operated by radio remote control.

1ajs · #76 Posted **Jun 13, 2008, 4:00 AM**

so how many abandond cranes do they have there now?

Dubai is Takin all the cranes.

Manitowoc and Terex are the only public crane companies I know of. I'd love to see Liebherr become an IPO but I won't hold my breath.

Amanita · #79 Posted **Jun 16, 2008, 3:41 PM**

Wow, that pic of Dubai is mind-boggling. That must be Burj Dubai in that pic.
And cherynobyl is just freaky. Very freaky.

I know there are clusters of cranes in Dubai, even more than in that photo, but that photo of the tower is fake.
