New mining invention relies on Truco Rubber Rubber specialist Truco (Transvaal Rubber Company), through its associate company Table Bay Rubber Company in Cape Town, has supplied various custom solutions during the prototype and final development stages of a new diamond mining platform. Weighing some 350t, the Jet Rig is a purpose built jack up platform designed and manufactured by Alluvial Diamond Projects (ADP) for special mining operations in the Inter-tidal corridor (ITC), i.e. on the beach and in the ultra shallow water. The Jet Rig can move forward, backwards, sideways, up and down and even turn on its axis. The Jet Rig mining technology was developed for Namdeb from the experimental Jet Hex, which was a crawler-based machine using the same jet pumping technology. For the Jet Rig, Truco has supplied hoses ranging from 150 to 300 mm in diameter, while the Jet Hex was fitted with 200mm nominal bore hoses across the board.
