Reinforced concrete headgears in South Africa
Head frames developed by Roberts Construction Co, with special reference to structure for Riebeeck gold mine, near Welkom, OFS; it is virtually extension of circular shaft and rises 150 ft above ground level; structure itself, 35 ft in diam with 18 in. thick walls, was slid by Prometo system of moving form work.
