Installation of two 140-tonne drive motors and four 90-tonne mill stands using a hydraulic gantry system during the first phase of Hot Strip Mill 1700 reconstruction.
The first phase of the Hot Strip Mill 1700 reconstruction focused on installing the core mechanical components that would form the foundation of the new rolling line. Metinvest entrusted our team with the precision installation of two fully assembled drive motors with a combined weight of 140 tonnes, followed by the installation of four 90-tonne mill stands—the structural supports that would later carry the Roughing Mill. Completing this phase was essential to keeping one of Ukraine’s largest steel plant modernisation programmes on schedule.
Working inside an existing steel production facility required a lifting solution capable of delivering exceptional precision where conventional cranes could not operate efficiently. Using an SBL1100 hydraulic gantry system, our engineers safely lifted, positioned, and aligned each component within strict installation tolerances. After completing the drive motor installation, the gantry system was relocated to another section of the mill to install the four 90-tonne stands, creating the structural platform for the subsequent installation of the 640-tonne Roughing Mill. The project demonstrated meticulous planning, controlled execution, and the precision engineering required for complex steel plant modernisation.
Successfully installed the primary drive motors and mill stands, completing the critical first phase of the Hot Strip Mill 1700 modernisation programme.
