Installation of a hydropower plant in an existing building

Project report: installation of a hydropower plant in an existing building

Moving in and installation support under difficult site conditions

Not every project can be planned by the textbook. When moving a modern hydropower plant into an existing building, the Omega Mounting installation team faced a particularly tricky task: a dilapidated access road, confined space and a riverbed that had to be drained before installation could even begin.

Our task was to move the individual plant components into the building and actively support the installation team on site – from crane logistics to the final positioning of the components. This project report shows how hydropower plants can be installed successfully even under difficult starting conditions.

A challenging starting situation on site

The installation crew in action

At the time of the project, the building was still being refurbished. This brought a number of challenges that had to be solved first.

The entrance to the building was in poor condition; in some places the concrete had already worn away. Driving the crane directly across it was therefore not possible.

To ensure the access road could bear the load, large steel plates first had to be delivered and laid out so that both the crane and our machine skates could travel safely over them. Only then could the actual installation begin.

The right crane for confined spaces

The V-Kart crane

A V-Kart crane was used for this project – compared with a conventional mobile crane, it offers several decisive advantages: it is more manoeuvrable, can travel with a raised load and, thanks to its low, compact design, is ideal for jobs with little space.

The drawback on this site: the tyres, which are not designed for off-road use, and the resulting low ground clearance. That is precisely why laying the steel plates beforehand was so crucial – it was what made using the crane on the uneven ground possible in the first place.

Dewatering & first moving in: the hopper

Once the access road had been secured with steel plates, installation could finally begin. The first component to be moved in was the hopper.

To do this, it was lifted in from the river side and initially set down on planks. We then used chain hoists to pull it precisely into the opening in the building provided for it.

To prevent water from entering the work area during installation, the riverbed and the building were sealed off with timber shoring and numerous sandbags.

Throughout the entire installation period, pumps kept the area reliably dry.

Safety and shoring on site

There are not always ideal lifting points or a ready-made standard solution. On projects like this, it is important to assess directly on site what is feasible – and which safety measures are needed to ensure the components can be lifted in smoothly.

To achieve sufficient stability, several beams were supported with steel props and timber baulks were driven into existing structures at specific points. This ensured that the structure could safely withstand the loads occurring during the rest of the installation.

Moving in the main components of the hydropower plant

Once the hopper was firmly in place, the actual hydropower plant could be moved in. The biggest difficulty: defining the lifting accessories so that there was enough space during moving in while the load hung exactly level. In addition, the lifting accessories could not be too long, as the distance between ceiling and floor left only limited room for manoeuvre.

Thanks to clearly defined lifting points and their compact design, moving in the large electric motor and the hydraulic power unit was comparatively straightforward. Positioning the arch was more demanding: it had to be carefully brought into the right position using a round sling and a chain hoist so that it could be fitted precisely.

Securing and handover to the concrete works

Once all components had been aligned and positioned, the last step before final fixing followed: additional supports were installed to hold the plant securely. Using a welding set, we also fitted brackets and supports at the appropriate points.

The following day, the plant could finally be concreted in and thus permanently anchored in the building.
