Lifting and skidding of 2 turbines and 2 steam turbine generators in Assiut, Egypt

ALE has successfully completed the lifting and skidding of 2 high pressure turbines and 2 steam turbine generators in the Assiut Power Plant, Egypt. The turbines, weighing 97t each, and the generators, weighing 300t each, were lifted using a skidding gantry on static frames and skidded along 60m. The turbines and generators were transported to the foundation by conventional trailers, where they were lifted by 2 strand jack units of 200t capacity. This manoeuvering of the pieces was carried out perpendicular to the foundation. The pieces were then rotated by a rotating spreader beam, which was part of the lifting system. Once the heavy pieces were raised to the upper level, above the level of the foundation, the gantry was skidded along 60m by SS300 push-pull units. The skidding beams were extended along 60m, where the first 40m were modular beams that were anchored to the foundation. The use of a rotating spreader beam and modular rigging allowed both the turbines and generators to be rotated while suspended, saving time during and in between the manoeuvres. The lifting of the turbines and generators was the culmination of a project in which ALE also transported and lifted 40 boiler modules.
