Bangladesh-based MKK Logistics has used an Enerpac SBL900 hydraulic gantry crane to install a 130-tonne turbine  at a 718 MW combined-cycle power plant at Meghnaghat in Dhaka.

Enerpac - MKK Logisitcs - HPIP turbine lifted to 14m mid-res

Combining the high pressure (HP) turbine and intermediate pressure (IP) turbine into a single casing, the HPIP turbine is a compact turbine with a smaller installation footprint. The challenge facing MKK Logistics was how to lift the turbine 14 m to the second floor of the power plant building and then install it.

“Given the lack of space and restricted building access, we felt confident that our compact Enerpac SBL900 hydraulic gantry could be used to progressively lift the turbine and then position it ready to be fully installed,” said Taher MD Ilias, assistant general manager at MKK Logistics.

First the SBL900 gantry and skidding track were hoisted to 14 m using the building’s overhead crane. Once assembled the gantry was skidded above the turbine. Using linked steel wire slings attached to the gantry header beams, MKK Logistics first lifted and held the turbine at 7.8 m while a steel platform was put in place to rest the turbine on. For the final lift to 14 m, single slings were attached to the turbine and SBL900 header beam, and the gantry raised clear of the building’s second floor.

The HPIP turbine was then skidded to a resting place. Although the turbine was facing the right direction, the SBL900 gantry and skid track had to be reconfigured by 90 degrees to skid the turbine into its correct position ready for installation.
