August 2012

Sarens provided an A to Z solution for the removal of old rings and the installation of new rings at Arcelor Mittals blast furnace in Brazil.

Five old furnace rings weighing 750t each were first lifted with Strand Jacks, skidded out of the furnace building, then lifted with a gantry and finally lowered with the Sarens Multi Lifting Tower (SMLT) equipped with Strand Jacks. SPMT's transported the rings to temporary supports.The three new ring sections were installed using the same technique.

The Sarens team executed all lifting operations working continuously in shifts 24/7, resulting in a serious time reduction.
