Gantry removes generator
By Christian Shelton23 April 2021
Algerian heavy lift company, Global Freight Transit SARL, used an Enerpac SBL1100 hydraulic gantry to remove a 470 tonne generator at the Koudiet Eddraouch power station in El-Tarf province, 700 kilometers east of Algiers, Algeria. The telescopic gantry allowed the safe removal of the generator, and its subsequent re-installation, following routine maintenance.
One of the largest combined-cycle power plants in the region, Koudiet Eddraouch power station has a production capacity of 1200 MW. According to Enerpac, maintenance of generators can be difficult within the confines of a power plant. The SBL1100 gantry was used to lift the generator 4.1 metres onto supports, allowing maintenance work to be completed before it was lowered back into its housing.
“The Enerpac SBL1100 is invaluable for this kind of lift where we have heavy loads and limited workspace,” said Sofiane Issiakhem, logistics coordinator, Global Freight Transport. “Ease of deployment and operation of the gantry has allowed us to safely conduct similar generator lift projects in another powerplant nearby. “
The SBL1100 is Enerpac’s highest capacity boom style gantry. Equipped with three stage lifting cylinders, the SBL1100 lifts up to 12 m at the top of the third stage and can handle up to 1178 tonnes at the top of the first stage.
As standard, the SBL1100 has an Intelli-Lift wireless control system allowing unobstructed views of the load. The wireless system is designed to provide automatic synchronisation of lifting with accuracy of 24 mm and automatic synchronisation of travel with accuracy of 15 mm. The gantry control system allows users to operate the lift locally at each leg or via the Intelli-Lift remote control. For enhanced durability, the SBL1100 offers a sturdy, proven base frame that can withstand a variety of environmental conditions.
