The SPX STONE range of DC power units is gaining increasing support in the South African mining industry.

“This year, we have sold this range of power components for applications ranging from mobile lifting systems to carryout maintenance on overhead power lines to emergency locomotive brakes,” reveals Power Team general manager Ian Bennett. “On the latter, the SPX STONE unit is used to charge the accumulator on the emergency brake system. The accumulator, in turn, is connected via a solenoid valve to the brake calliper, for instant, reliable response when needed,” he explains.

UNIQUE MODULAR PROJECT

Since introducing Jetfloat at the beginning of 2006, BET has successfully penetrated the local market for floating platforms and walkways required for applications that include mining and industrial process operations, as well as jetties and marinas for various marine, fishing and recreational purposes.

“Before we introduced Jetfloat users of floating walkways and platforms had to make do with constructions mounted on metal or plastic fuel drums, or similar improvisatory solutions,” says BET spares and services manager Paul Davies.

MDME TURNAROUND

“We are currently involved in Southern African mining projects worth some US$350 million (close to R3.5 billion), and we are completing feasibility studies which we expect to convert to contracts worth anywhere between US$700 million (R5 billion) and US$1 billion (R7 billion) in the next two to three years,” says CEO George Bennett in an exclusive interview with Mining Review Africa.

“This period has been one of significant progress for PDF,” he reveals, “and in the period ahead to Q1 of 2008 we intend progressing the evaluation of these projects with the objective of being in a position to make commercial mining go-ahead decisions in H1 of 2008.”

GEM DIAMONDS SPARKLES

The first half of 2007 saw the company develop an increasingly strong production pipeline, with new mines coming on stream and significant production increases expected from various operations over the medium term.

“Our notional turnover (the amount of money we manage on behalf of our clients on projects) for the 2006 financial year to February 2007 was R5.5 billion – an increase of more than 60% over the R3.5 billion achieved in the 2005 financial year,” he reveals. “Our current confirmed work-load will see us achieve our objectives for the next two years,” he adds, “and the secured workload for 2007 and 2008 should show a further significant increase each year over the R5.5 billion for 2006. And there is of course the upside potential of further opportunities we expect as we go along.”
