The crane is the fourth generation of the SGC [ Sarens Giant Crane] series. With a maximum main boom length of 160m, the crane can be equipped with or without a fly-jib and it can operate on a ring or on straight rails. At Hinkley Point [C nuclear power project], the SGC 250 will travel along 6km of rail that is being laid in preparation for it. This means that it can travel between three different lift locations without the need for disassembly or reassembly.
At Hinkley Point C the crane will lift components ranging from 50 tonnes to 1,150 tonnes at radii of up to 165m. It will pick up and install prefabricated concrete elements, steel structures and reactor equipment directly from each prefabrication position. A second crane, a 600t-capacity Terex Demag CC 2800, will assist as a rigging crane.
There are many ways of defining the size of a crane; the basis of Sarens’ claim for world’s biggest appears to rely on the machine’s nominal load-moment – the load it can lift at a given outreach. And as CEO Carl Sarens explains, outreach isn’t necessarily the same as radius.
“Radius equals the distance from the centre of rotation to the lifting position; outreach equals the distance from the boom pin to the lifting position. For our clients, it’s the outreach which has most value,” he says.
Crucially, the geometry of the SGC 250 means that the boom hinge pin is located 19m from the centre of rotation. The absolute maximum lifting capacity of the machine can be achieved when it is rigged with 118m of main boom and 5,200 tonnes of counterweight sitting on the 48.5m-diameter slewing rails on the opposite side from the boom pin.
Working at 40m radius, the crane’s outreach is 21m – because the boom pin is situated 19m from the centre of rotation. At this outreach, and in this configuration, the SGC 250 can lift a load of 5,000 tonnes, says Carl Sarens.
“On an outreach of 21m, the SGC-250 is the only crane that can reach 5,000 tonnes capacity with a main boom of 118m,” he concludes.
Other contenders for ‘world’s biggest’ include Mammoet’s PTC 200 DS and ALE’s AL.SK190, used by contractor Keltbray on the Earls Court demolition project in London last year.
Load tables for the PTC 200 DS – rated at 200,000 tonne-metres – show that, when rigged with 117m of main boom a maximum load of 3,200 tonnes can be lifted at a radius of 46m, or an outreach of 26m.
The AL.SK190 boasts a lifting capacity of 4,300 tonnes, a load moment of 196,000 tonne-metres and a maximum boom height of almost 200m – although it was rigged with only 120m of boom at Earls Court.
ALE also has the SK350, which rivals the SGC 250 with a maximum rated lifting capacity of 5,000. This machine has a nominal load moment of 354,000 tonne-metres. ALE says it has designs for doubling up the SK350 to make the SK700, with two winches and booms in parallel lifting 8,000 tonnes with a load moment of 708,000 tonne-metres.

The day after I discovered the above links, I came across information about an ALE SK350 crane.
 |
| CBC 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.

And some posts lie. Thank goodness for comments.

| Crane Operators Forum - Heavy Lift profession. posted 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 |
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. |
Adavid added two comments to the 36k mt post with the text: "This sk 350 is good for 5k tonn."

And in Toledo, OH, they are claiming a LR 13000 is the largest crane in the world. But it can lift "just" 3000 metric tons and needs "just" 218 truckloads to haul.

| Mammoet posted Mammoet's SK6,000 crane features in this month's Cranes Today !Read more: http://ow.ly/JUfi50D9hWm The SK6,000 will increase the efficiency of FPSO [Floating Production Storage and Offloading] and FLNG [Floating Liquefied Natural Gas] construction, allowing integration of of modules exceeding 3,000 and even 4,000t. The SK6,000 is containerized and can be assembled quickly on site, delivering super heavy lift capability to anywhere on Earth. [Mammoet is "just" 4,000t. Given the name, I wonder if they plan on doing a 6,000t version. In fact, it has been announced. And the 6,000 figure is tonnes or 6,614 tons. It will also be able to handle "a 1,654-ton 492-foot tall, flare tower in one piece."] |
Meanwhile, ALE is going for 10,000 tonnes.

| KHL |
Of course, the bar keeps going up (May 2021). But it is important that the correct adjectives be used. I don't know what the qualifiers should be for this crane because it can lift just 5000 tons. (I don't know what kind of tons.) But the boom is 820' so maybe it is the biggest in terms of load moment.

| Mammoet posted Due to the global demand for SK cranes and for even greater capacity, the SK350, launched in 2013 has now taken its place as the world’s largest capacity land based crane by some distance. With a lifting capacity of 5,000t and a load moment of 354,000tm [252m radius], this crane enables the development of new and groundbreaking construction methodologies. It can save our clients time and money on the construction site by reducing schedule, risk and cost. To watch the SK350 in action in Newfoundland, #Canada, check out: https://mmoet.me/2WnxX4A [A YouTube video] The SK350 minimized disruption to the site as it lifted from one location, away from other ongoing activities. [Do they hook up those two anchor lines when high winds are predicted? Actually, they probably do it between lift jobs. Because they have to build the modules first, I doubt if it does lifts very frequently.] Richard Thornton: https://www.ale-heavylift.com/sk10000/ [This crane also pivots around the ballast box.] James Chamberlin: Guarantee nothing about the rental of that crane saves money. |

| Crane Operators Forum - Heavy Lift profession. posted One of the world's largest cranes set a new world lifting record, lifting 36,000 metric tonnes! [Talk about "click bait." Actually, a AL.SK350 lifted 40 modules that totaled to 36kmt. That crane is called the world's largest, but it can lift "only" 4kmt. [dyneema]] Bjørnar Berg: Heaviest lift ever lifted by a single shorecrane is 20133 metric tonnes during testlift of the Taisun crane at Yantai Raffles shipyard. Single biggest offshorcrane is located onboard Chen Hua 30, lifting 7000 t revolving and 12000 t over stern. [Some comments on the post debate if stationary cranes should be considered cranes.] [ALE is Abnormal Load Engineering, and it was bought by Mammoet in 2020. [YouTube]] |
 |
| dyneema "The benefits of going cutting-edge became clear in early 2017 when the crane/sling combination set a new world lifting record. At more than 3,000t, it was the heaviest commercial load ever to be lifted by a land-based mobile crane." [I noticed that the AL.SK350 was called a mobile crane. I guess that is because its parts fit in containers and it can be shipped from place to place.] |
Now back to some crawlers
 |
| safe_image for Liebherr announces 2,500 tonne crawler crane "The LR 12500-1.0 fits in the upper end of the product range between the 1,350 tonne capacity LR 11350 and the 3,000 tonne capacity LR 13000....Easy transport is a key element of the new design. Largest is the 4 metre wide superstructure front section which can be transported on a low bed trailer. Other components come in at 3.5 metres wide or less. Crawler units can have the tracks removed to reduce the 150 tonne overall weight of each one. Without tracks the crawler frames each weigh 97 tonnes and they can be split further, into two pieces. Counterweight slabs are the same 25 tonne concrete ones as used on the LR 13000. They have twistlocks on each corner and can be transported like a 20 foot container." |
So is this the largest in Australia instead of in the world? That is what come comments seem to confirm. Also Sany SCL must be a Chinese company.
 |
| safe_image for Largest ever lattice boom mobile crane arrives in Australia "With 133m of main boom and 12m of fixed jib, the 1,000t capacity crane was being commissioned before delivery to its first job at a wind farm site in Queensland." |
And now a crawler crane can do 4000 tons.
