EQUIPMENT
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
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.
