HLI supplied the equipment and engineering analysis required for the installation of a roller at the Women’s Bay 3 Power Plant in Tampere, Finland. The scope of work included unloading, lifting, and positioning the roller into its final installation location. During the lifting operation, two sets of hydraulic strand jacks were used, each set consisting of 2 jacks with a lifting capacity of 40 tonnes per jack. To avoid interference with surrounding structures, the roller had to be transferred between the two sets of jacks during the operation.
Scope of Works
- Roller weight: 40 tonnes,
- Lifting/transport distance: 40 m,
- Design of vertical and horizontal transport concept,
- Design, supply, and installation of temporary supporting structures,
- Provision of mechanical and hydraulic technology for transport operations,
- Comprehensive horizontal and vertical transport service.
Step 1
The drum is delivered to the boiler on an SPMT and lifted using strand jacks. Tilting is required due to the geometry of the boiler structure.
Step 2
The drum is lifted, leveled, and secured in a horizontal position.
Step 3
A second set of strand jacks is connected to the system using a triple connector, and the load is transferred to the second set of actuators.
Step 4
The first set of strand jacks is completely unloaded, then the first set of actuators is disconnected from the triple connector.
Step 5
The second set of actuators with the attached drum is moved horizontally.
Step 6
The drum is lifted and secured in its final position, and the drum suspension is installed.
