Doosan’s new generation of machines boasts an impressive combination of power and intelligence, which means operators can handle heavy loads and challenging tasks with ease.

with ease,” says Darrel Holton, managing director, DISA Equipment Limited, trading as Doosan, part of Invicta Holdings Limited. “All features of this series have been optimised for a greater working range and fast digging speeds required for high performance in tough applications.” This bodes well in South Africa, due to the local climate and conditions that are varied. “The DX450LCA-7M excavators, with an operating weight of 44.3 tons and DX450LC-7M machines, with an operating weight of 44.4 tons, can operate efficiently with attachments designed for 50-ton excavators, with sufficient pump flow and lifting capacity.” Doosan’s new DX12 engine, with outputs of 181 kW and impressive torque, delivers the precise power needed for each specific task. A rotor-type pre-cleaner ensures efficient filtering in dusty environments, which increases maintenance intervals, resulting in more uptime. In addition, a filter-type water separator filters moisture in the fuel, which reduces impurities and enhances engine efficiency. A standard auto-idle feature reduces engine rpm when the steering wheel or joystick isn’t being used and automatically puts the engine and pump into standby mode when it detects a pause. This function helps reduce fuel consumption and minimises noise. Notably, the noise levels of this series comply with environmental regulations. In addition, the e-EPOS system (Electronic Power Optimising System) ensures economy and smooth operation, by providing a synchronised communication link between the engine’s electronic control unit and the hydraulic system, to ensure power is delivered exactly as required.
