State-of-the-art
cooling system
• The 4-way combination radia-
tor cools the charge air, cooling
water, fuel and the hydraulic oil.
• The hydrostatic fan affords an
excellent cooling performance
and guarantees uninterrupted
operation even under the most
demanding of conditions.
• The wide-meshed radiator is
largely self-cleaning and mini-
mizes the risk of blockages.
Endurance-tested structure
• The fatigue resistance and the
high torsional rigidity of all steel
components were tested under
maximum loads using test
benches.
• The operator’s cab is equipped
with ROPS (Rollover Protective
Structure) and FOPS (Falling
Objects Protective Structure)
• The main frame and track roller
frames are of box-type design
and are lifetime-tested.
