Phase 3 of the development was ideally suited for the inaugural use of PERI’s RCS hydraulic self-climbing system in South Africa. There are 39 RCS climbing rails in use, forming 18 climbing units.
The lift core structures posed some special challenges, including: changing door opening levels and locations, varying pour heights and changes in shaft geometry – which varied from closed boxed sections, to open U-section scenic lift arrangements.
In general, the RCS system has worked well for WBHO. The support from the PERI team is, as always, of an excellent standard.
The flexibility of the RCS platforms ensured that planned in-situ modifications were easily completed once they emerged from the closed shaft formation at ground level.
