EQUIPMENT

clogging of the air breather, resulting in elevated oil temperatures and damage to the seals on the axles. Buckets have been reinforced for additional strength. Aluminium radiators are installed on rubber mounts to dampen vibration and the radiator grille is made of reinforced steel for increased shock resistance. A cover has been fitted to the propeller shaft to protect the oil seal from dust and foreign objects. The design of the DLA series has also been improved for enhanced operator comfort. There is more space in the cab, improved visibility, push button controlled air conditioning and heating, a comfortable air suspension seat and convenient storage space.

Features for operators also include precise control levers, a high visibility central indictor panel, sun visor and room mirror, an adjust- able steering column and arm rests for added comfort. Features for easy maintenance procedures include the radiator fan which swings out for effortless cleaning and remote drain valves are easily accessible for convenient draining of fluids. The air conditioner condenser is accessed directly by tilting the grille. The Doosan range of earthmoving equip- ment, which is manufactured in South Korea, copes efficiently in diverse sectors, including industrial, construction, civil engineering, agri- cultural, mining and quarrying environments.

The cooling compartment is separated from the engine compartment to allow better control of air intake and prevents warm and dusty air from entering. A 3-stage air filter is fitted with a turbo 3 cyclone dust separator. A hydraulically driven fan for improved productivity and reduced noise levels, is standard. Improved strength These machines have higher static tipping loads at maximum reach with a straight frame DL300A (13 650 kg) and DL420A (17 900 kg). Other quality improvements of the DLA series include a new hose, which is installed in the air breather of ZF axles to prevent breather congestion problems. In other wheel loaders, dust and sand cause
