DISD SD310 wheel loader series from Doosan The DISD SD310 wheel loader series from Doosan is known for high perfor- mance and cost efficient operation in tough operating conditions. The SD310 wheel loaders are

soft, muddy ground, reducing the risk of skidding and preventing excessive tyre wear. The SD310 wheel loader series has a solid frame structure for improved strength and for enhanced safety on site. The new streamlined design of the machine has broadened the rearward visual field by approximately 20%. The machines have been designed for quick and effortless maintenance. A 180˚side-opened maintenance window provides a direct view for efficient daily inspection procedures and a full tilting engine cover enables easy repair to the engine and components. For user con- venience, brake discs can be replaced without disassembling the hub. Features for enhanced operator control and greater comfort include a spacious, low-noise cab, with efficient air-circulation and a newly-designed instrument panel, which provides critical information, including fuel and voltage

powered by a fuel-saving, Tier 11 6-cylinder turbo, direct injection engine, that delivers 160 kW (215 HP) @ 2 000 rpm. High power and torque characteristics, coupled with efficient synchronisation of the drivetrain with the hydraulic system, ensure optimum productivity, even in arduous working conditions. The range comes with a 3 m³ bucket, with optimised breakout force and improved machine balance. The operating weight of the series has been increased, with greater tipping load capacities. Fully automatic ZF transmission facilitates streamlined speed change, with four forward gears and three backward gears. Maximum tractive force ensures easy driving over

NEW HYUNDAI R850LC-9 EXCAVATORS EXCEL IN SOUTHERN AFRICA

around the clock for Basil Read in difficult conditions at a diamond mine in Lesotho, as well as for Rhino Earthmovers at a gold mine in Gauteng, fitted 10 t Xcentric Ripper hydraulic attachments,. The 85 t R850LC-9 excavators have advanced Tier 3 engine technology for fuel efficiency and hydraulic sys- tem improvements ensure enhanced performance, smooth operation and precision-control. A newly-designed pump compartment controls func- tions like two speed travel, power boost, auto boom-swing priority and a safety lock. The strengthened undercarriage improves performance of these machines in arduous operating conditions, particularly in the mining and quarrying sectors. Durable covers have been specially designed for these machines, to protect travel motors and hoses against damage from rocks. l

Newly-launched Hyundai R850LC-9 excavators – designed for high power and superior performance – are said to be excelling in tough southern African conditions. “HPE Africa’s commitment to the local market is to keep abreast with global trends in construction equip- ment. This initiative encompasses the regular launch of new machines, with specific advancements and modifications, to meet exact South African operating conditions and customer requirements,” says Alex Ackron, MD of HPE Africa.

“Hyundai R850LC-9 machines, which replace the R800LC-9 model, have recently been introduced locally by HPE Africa. The excavators, which are partially assembled on arrival, are constructed to exact customer requirements. Components like the dipper, boom, counterweight, bucket, hammer piping and side rails, are imported loose and are proudly assembled by the HPE Africa team.” Several R850LC-9 machines are hard at work in southern Africa, operating efficiently, for example,
