HLI provided equipment and services for lifting elements of a warehouse roof. The objective was to raise the roof beams to a sufficient height to insert a flexible underlayer beneath them. A hydraulic jack system along with a patented steel structure was used. A total of 18 base elements required lifting. Access to the work area was limited, and delivery schedules were tight. HLI supplied all certified lifting equipment, including hydraulic jacks, pumps, connecting elements, and accessories. Supervision and direct operation of the equipment were also provided by HLI.
Scope of Works
- Applied lifting force: 100 kN,
- Number of elements: 9,
- Lifting height: 20 mm,
- Design of installation concept,
- Design and supply of temporary supporting structures,
- Provision of hydraulic technology and operation.
- Comprehensive horizontal and vertical transport service.
