797FFeatures HighEnginePerformance The Cat C175-20 engine offers
the perfect balance between power, robust design and economy.
PowerShiftTransmission Electronic Clutch Pressure Control (ECPC)
gives the 797F seven speed transmission smooth shifts while
providing constant power and efficiency for peak power train
performance. ReliableMechanicalDriveSystem The Cat mechanical drive
power train provides unmatched operating efficiency. RobustBraking
Cat oil-cooled, multiple disc brakes offer exceptional, fade
resistant braking in all haul road conditions. TruckBody A variety
of Caterpillar designed and built bodies and liners ensure optimal
performance and reliability in tough mining applications.
ComfortableCab Large, spacious cab offers unmatched visibility and
exceptional operator comfort. EnhancedServiceability Designed with
improved serviceability points and grouped service locations so
more time is spent on the haul road.
