HLI executed the lifting of two ECO modules, each weighing 190 tonnes. The operations were carried out using hydraulic strand jacks with a lifting capacity of 40 tonnes each. The modules were assembled in sections in a “curtain” method, where the lifting elements allowed each subsequent section to be raised and secured from below. Upon completion, the full ECO module was lifted into its final position. HLI supplied all certified lifting equipment, including strand jacks, pumps, connecting elements, and accessories. Supervision and direct operation of the equipment were also provided by HLI.
Scope of Works
- Element weight: 190 tonnes,
- Lifting height: 45 m,
- Provision of Strand Jacking technology
- Supervision of temporary structure assembly and supplied technology,
- Comprehensive service for the lifting and positioning of modules.
Step 1
ECO superheater components were delivered to the lifting area using self-propelled modular transporters (SPMTs). The first component is the outlet duct. Dedicated lifting devices are attached to the component to be lifted.
Step 2
The first component is gently lifted from the SPMT platform to a height that allows the transport of the next component.
Step 3
The next ECO component is moved underneath the previously lifted component. The upper component is lowered and positioned onto the first superheater component.
Step 4
The entire assembly is lifted to a height that allows the transport of the next component.
Step 5
The lower and upper components are connected using dedicated pins. This operation is repeated until all components are fully assembled.
