As part of a renovation project at the Linth waste incineration plant in Niederurnen, our team installed a new steam turbine and generator in an existing building. The plant components weighed up to 60.5 tonnes – but the real challenge of this industrial installation lay in the confined space and difficult access to the final location. Careful planning and comprehensive preparation resulted in a solution involving a load-bearing heavy-duty platform.
The machine parts were delivered just-in-time to the installation site. The day before, we had already installed the hydraulic lifting column system on the upper floor of the plant, including the rail system, which was supported by additional lifting columns outside the installation opening.
The 60.5-tonne lower part of the turbine (see photos and video) was unloaded with the help of a mobile crane, prepared for lifting, placed several metres above the ground on the temporary heavy-duty platform and secured with rope pulls. This enabled us to pull it into the building in a controlled manner, several metres above the ground. Internally, we transferred the heavy load to our lifting equipment in order to position it precisely on the prepared foundation above the exhaust pipe and set it down there. We were also able to transport the remaining machine components into the building in the same way, position them and prepare them for assembly.
Equipment:
- 90-tonne hydraulic lifting system
- 32 t hydraulic lifting system
- Steel girders and rail system
- Heavy-duty round slings and shackles
- Wire rope hoists
- 5 t forklift
- PSAgA equipment
- Various transport and truck crane vehicles
