Hauler Features Higher Operational Efficiency
Caterpillar says its new 70-ton-payload
(63.5 metric ton) 775G off-highway truck
combines new drive train strategies and a
5% power increase to give it enhanced efficiency
over its predecessor. To balance fuel
savings and production, two different economy
shift mode selections enable the user
to tailor performance to the needs of the
application, while advanced control systems
also integrate the optional engine
compression brake with Automatic
Retarder Control to enable faster downhill
travel and reduced cycle times―without
increased fuel consumption. To meet Tier 4
Final emissions regulations in the U.S., the
Cat C27 ACERT engine includes a NOx
reduction system and diesel oxidation catalyst.
The system requires the use of ultra
low sulphur diesel fuel and does not use a
diesel particulate filter.
The 775G also features a new cab
design. The operator seat is now in the center
of the cab, which provides more space
for the operator, and the cab has access
and egress from either side with stairs illuminated
by LED lights. The 775G has a
ground level electrical service center and
diagnostics port on the front bumper. Cat’s
VIMS data collection system is standard
equipment on the 775G, and an optional
VIMS service light on the front of the truck
will indicate any machine event that affects
performance. Fluid level indication and
fluid fill ports are grouped for efficient service,
and fluid filters are grouped. Filter
service intervals for steering, hoist/brake,
and transmission/torque converter have
been increased from 500 to 1,000 hours.
