7 Crawler loaders in tunnelling
Reversible fan
When working in an environment
that is subject to excessive grime
and mud, the self-cleaning feature
of the reversible fan is activated.
The reverse air flow will remove all
particles attached to the inside of
the radiator block. This will sub-
stantially improve the cooling effect
and reduces the cleaning.
Filler guard
A solid guard reduces the risk of
damaging the diesel filler neck. It can
be fitted in combination with a tank
guard.
Hydraulic oil temperature gauge
The gauge allows monitoring of the
hydraulic oil temperature and prevents
overheating.
Engine air pre-cleaner
The centrifugal force of the pre-clean-
er removes dust particles before they
reach the filter. Especially in dust-in-
tensive use, e.g. in tunnels, the pre-
cleaner ensures pure air is drawn in.
The system permits a longer life of the
filter cartridge, helps to reduce wear
and to increase the engine’s life ex-
pectancy.
