ALE SK350 can lift at least 4000 tons, SGC-250 does 5000 tonnes

It can lift 4000t with a winch and 5000t with strand jacks. A comment pointed out that the mobile crane helping to place the counterweights would normally be considered a big crane. Each counterweight is a specially reinforced 40' container that is filled with locally available material such as sand or gravel. A filled container is 100t and 4000t of ballast material is needed. [brochure, p 21] The crane was designed as pieces that will fit in shipping containers. It can be assembled in four weeks using a 400t crawler crane. [brochure, p 17] The counterweight assembly is supported on tracks so that the ring can be replaced with a straight track and the whole crane moved on site in just a few days. [brochure, p 25]

ALE has used its innovative heavy duty jib for the first time with the AL.SK350 crane whilst performing the inaugural lift, weighing 1,276t, of an FPSO module integration project in Nigeria https://goo.gl/BZ3eKk.

Inaugural Lift
"The world’s largest capacity land based crane, the AL.SK350, has been rigged in its current biggest configuration with a 124m a-frame main boom, 49m ballast radius and the 38m jib for additional outreach, along with a heavy winch system and 4,000t ballast for the project in Lagos."

Inaugural Lift
Another of the six modules they are lifting into place during March and April, 2018.

The ALE SK350 crane was launched in 2013 with a lifting capacity of 5,000t and a load moment of 354,000tm. The AL.SK cranes are also available in AL.SK190 and AL.SK700 configurations, achieving capacities up to 4,300t and 8,000t respectively. Furthermore, the cranes can be equipped with a 3,400t capacity heavy duty jib. The jib is being used on an FPSO module integration project in Nigeria. [ale-heavylift]

SARENS LAUNCHES THE LARGEST CRANE IN THE WORLD: THE SGC-250

A beauty the most powerful of all
Barry Cole: What are two white? Lines from ground to midpoint? Tie downs, for wind, storage?
Christian Sturm: Barry Cole it's called Wind Ankers keeps the SK350 stable during high wind force.
Matthew Chavez: Christian Sturm are these added end of day, long off periods, or work with daily functions?
Christian Sturm: Matthew Chavez no only if they get high winds ! Otherwise you have to boom down all the time with the Wind Ankers you can have the SK350 boom up to 120km/h.
Gaetan Rahrojan: Formerly ALE crane

It looks like they just flipped the above photo.

Blake LeDrew: Argentia Newfoundland

Brian Verhoeven: why would the boom be tethered to the ground at the gib connection?

Blake LeDrew: Brian Verhoeven for high winds over 120km/h.

Liebherr sk350....

The AL.SK350 is one of the largest land-based cranes in the world. (Twitter)

It can lift up to 5,000 tonnes. Its boom is 124 metres long — longer than two NHL-sized ice rinks placed end to end.It arrived in Newfoundland in 200 shipping containers, requiring 300-tonne cranes just to piece it together.
Impressive, but none of that is why it's so vital to Husky's operations, as workers piece together a platform that will eventually be floated out to sea and capture offshore oil.
"The real purpose of this crane is just its reach," said Sandy Nairn, vice-president of the West White Rose Project.
ALE designed and built the crane, part of a line of cranes it launched in 2013, and the company website describes the AL.SK350 as "the largest capacity land-based crane in the world by some distance."
That 163-metre reach means it can lift almost anything on the Argentia site, even though the crane itself is stationary.
...
The crane will be in Argentia until early 2020, when it will be then broken down again into its small parts and shipped off to its next international destination.

The massive ALE SK350 crane, one of the largest land-based cranes in the world, will safely and efficiently install fully assembled interior components at the West White Rose Project in Argentia. Learn more at: http://wwrp.huskyenergy.com/Project_overview …

And some post descriptions are wrong. Thank goodness for comments.

One of the world's largest cranes set a new world lifting record, lifting 36,000 metric tonnes!
Ruud van Sprundel: In 30 lifts combined yes
Bjørnar Berg: There is no crane lifting 36000 mT in one lift. The biggest shorebased crane is Taizun, lifting 20000 mt, and the biggest offshore crane is the 12000 mT crane on the chinese vessel Zhen Hua 30.
Edso Sluijsmans: there are a lot of cranes with more capacity. Mammoet/ALE PTC240 240.000 tm

Paul Anderson: That is EBR shipyard in San Jose de North, Rio Grande Brazil, lifting topside modules onto an FPSO, possibly Modec vessel that was in the yard for integration around 2021 or 2022. I was in the yard in 2016 working on FPSO P74, using similar ring crane, Module weight ranged between 2000 to 4200 tonnes, crane counterbalanced with sand filled containers which are the containers actually used to transport the crane to site.

[Another comment explained that after they build one side, they flip the ship around and build the other side.]

Omitting adjectives such as "combined" is a serious error.

Paul Krueger commented on the 36k mt post above
For those who like a little more detail, this was in Brazil and the owner is ALE's and the crane is a Kobelco SK350.

Christian Oseguera: Paul Krueger ALE doesn't exist anymore. They got bought by Mammoet.

Adavid added two comments to the 36k mt post with the text: "This sk 350 is good for 5k tonn."

[I've seen another source that also rates the SK350 at 5,000 tons.]
