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]
