Hyundai backhoe loader proves popular

and precise control, even in arduous oper- ating conditions. The backhoe boom allows for a clear line of site into a trench when the opera- tor is digging around buried constructions such as water mains, sewer pipes and util- ity lines. An optional extendable dipper increases versatility. Optional features for enhanced perfor- mance include the four-wheel drive system that improves mobility and an ‘automatic return to dig’function on the loader attach- ment that reduces loading cycle times. The ‘ride control system’ – also optional – has a shock absorbing accumulator that cush- ions the boom, reduces material loss and improves operator comfort. The operator is able to turn this system on or off with an overhead switch. Standard features are complemented by a choice of hydraulic systems that incor- porate the latest technologies for improved efficiency. These options include a load sensing hydraulic system that matches the engine power to the appropriate hydraulic flow, based on the load demand required.

This method prevents the impeller from turning off if the motor is started in the wrong rotation direction.” In all models, a robust one piece casing facilitates the flow of all types of solids and fibrous materials and an easily accessible stuffing box minimises blow-back of media around the shaft sleeve, without actual sealing contact. Another advantage of these pumps is that spares are completely interchangeable. Becker Mining South Africa, tel (+27 57) 396-2704

The Hyundai range of earthmoving equip- ment, available exclusively in Southern Africa from HPE Africa, includes backhoe loaders which have reportedly been well received by the local market. “The robust H930s backhoe loader series is particularly well liked by busi- nesses that need smaller machines, without having to make a substantial capital investment in large excavators and loaders,” says Alex Ackron, HPE Africa’s MD. “Hyundai backhoe loaders, with a

reputation for efficient performance, low operating costs and minimal maintenance requirements, are also popular with plant hire companies. The company supports this range with a two-year/3 000 hour warranty.” Hyundai H930s backhoe loaders are fitted with fuel efficient, low noise, envi- ronmentally friendly Perkins tier 2 diesel engines. Standard power shift transmis- sion and a convenient gear/shift selector enable fast, easy and efficient operation

Becker Mining South Africa’s extensive range of light, medium and heavy duty slurry pumps includes the HS range, avail- able in vertical, horizontal and submersible configurations. These pumps are designed for optimum efficiency, low maintenance and extended service life in diverse indus- tries, and under harsh operating conditions. Slurry pumps designed for optimum efficiency The HS pump range, which is man- ufactured locally to stringent OEM specifications, includes four different mod- els, in various sizes – from two to eight inch units. HS (horizontal hydro solids), VHS (ver- tical hydro solids), PVS (pumpmor vertical solids) and HTMS (submersible) pumps are said to be ideally suited to applications in

Huge GRP tank manufactured for uraniummine IWC recently completed the construc- tion of one of its largest-ever glass-fibre reinforced plastics (GRP) tanks measur- ing 6 m in diameter and 11 m in height and capable of holding up to 254 000 litres. The length of the cylinder of this tank was set at 9 m. IWC’s GRP manufac- turing facility in Isando, Gauteng, can manufacture up to14 m using a single filament wound process.

will store highly-corrosive chemical con- tents, including sulphuric acid. “IWC has already designed and manufactured 8 km of GRP piping and 17 GRP tanks for the mine’s process plant, but none as big as this one,” says Roger Rusch, CEO of IWC. “It took six weeks to manufacture the tank and the IWC team will now supervise its instal- lation at the Husab uranium mine’s process facility in Namibia.” GRP is a composite material that is highly resistant to all forms of corrosion, making it suited to solvent extraction processes.

The GRP tank was designed for Swakop Uranium’s new Husab uranium mine, near Swakopmund, Namibia, and will be used in the mine’s acid leach pro- cess plant as part of the uranium solvent extraction (SX) procedure. The GRP tank
