The awards, which focus on industrial, engineering and design excellence, were announced at a gala event in Johannesburg recently.
The designers and manufacturers of 15 products that have already proven successful in the market place received awards at the 34th annual event.
The Ekscalibur Water Cannon is a water-jetting gun that releases a sizeable 100kW of power to move broken rock in mines. This is approximately three times the power of a traditional hand-held jetting gun.
The reaction force of this powerful jet necessitates the need for the cannon to be clamped by means of a unique pressurised hydraulic prop. This dramatically reduces operator fatigue and enhances safety by placing the operator behind the cannon, well away from the jet and hose.
Cleaning performance is improved, eliminating the need for a face scraper.
The Pump Control Valve is designed to protect underground mine dewatering pumps against pressure surges associated with pump start-ups, controlled shut-downs and starting with the pump column empty or only partially full.
Operating pumps without such protection are a common problem in South African mines and can lead to premature pump-balance failure or wear and, at worst, seizing of the pump and possibly a burst column.
The Pump Control Valve incorporates a two-stage opening and closing process controlled by valves, which sense upstream and downstream pressure.
The main valve and the control valves are all energised by the pressure in the pump column, obviating the need for an external power source.
