A 32-storey residential tower with one core and a tight podium left no room for a second crane position. The contractor needed two hoists on the same mast line, working through the façade and fit-out phases without stopping.
Configuration
- 2 × SC200/200, 3 × 11 kW drives per cage
- 180 m of 650 × 650 mast, tie-ins every 6 m
- VFD on the façade-phase cage, contactor control on the second
- Ground control plus cage-top control for the final 30 m
Result
Both cages were commissioned in nine days. The VFD cage held ±5 mm levelling during panel installation, and the shared spares kit covered both units — no second inventory at site.
