Plant, Equipment & Site Operations
Precision work in a very confined space The logistical and technical challenges began right from the setup stage: first, the first LTM 1750‐9.1 was positioned and erected. This crane then assisted with the set-up of the second unit. During the tandem lift, the utmost concentration was required – particularly to ensure the load on the triangular crossbeam remained precisely and evenly distributed at all times.
“ A specialised operation in very confined spaces. A major challenge – but in the end, everything went to plan,” reports Manuel Bergmann, crane operator of the blue LTM 1750‐9.1. Michael Schmieder, operator of the white LTM 1750‐9.1, also emphasises the precision required:“ We had to work with great concentration and precision to keep the load on the triangular crossbeam and on both cranes constant. I’ m very relieved that everything went according to plan.”
The successful tandem lift impressively demonstrates how high-performance crane technology, careful planning and an experienced team enable precise and safe solutions even under the most difficult conditions. Once the main assembly was complete, one of the LTM 1750‐9.1s was dismantled, whilst the second crane was moved to the opposite bank to carry out further remaining work there.
Precision work: The LTM 1750-9.1 cranes had to be set up in a very confined space and then carry out their assembly tasks with great precision.
