Inaugural Lifts For Largest Land-based Crane
The world’s largest capacity land-based crane, the AL.SK350, has performed its inaugural lifts in Brazil, using its 4,000t winch system and high speed slew. ALE is currently using the AL.SK350 crane to lift and install approximately 40 modules, weighing up to 3,000t, onto the P-74 Floating Production, Storage and Offloading vessel (FPSO) in the south of Brazil.
The crane was selected by the client because it was the only crane capable of installing the modules complete and without additional relocation of the ship’s hull. This has saved the client considerable construction time and money in the construction schedule. The heaviest module on the project will weigh 3,000t, making it the heaviest commercial load ever lifted by a land based mobile crane.
ALE’s AL.SK350 crane has been rigged in its current biggest configuration with 49m-ballast radius and 4,000t ballast. The main boom is a 130m long A-frame design on a stable 18m-wide base. The crane is equipped with a 4,000t main winch system and 600t auxiliary quick winch system. For heavier loads of up to 5,000t, a strand jack lifting system can be installed.
With its 354,000tm load moment capacity, it is the largest capacity crane in the market by a significant margin.
