ACHIEVE GREATER PRODUCTIVITY
- ACHIEVE GREATER PRODUCTIVITY
- Haul your materials faster with an accelerated travel speed.
- Put more power to the ground with increased torque.
- Enjoy greater productivity while using a more responsive Traction
Control System (TCS). - Reduce tire wear with maximum by engaging TCS early in the slip.
- Strong, predictable performance helps operators achieve the lowest cost per ton.
BOOST FUEL EFFICIENCY
- BOOST FUEL EFFICIENCY
- Up to 11% less fuel consumption.
- Advanced Productivity Electronic Control System (APECS) allows the engine and transmission to communicate on a high level. This communication allows the machine to better utilize the power and torque the engine is producing.
- Automatically optimize fuel consumption with the feature—Adaptive Economy mode reduces fuel use without affecting productivity and can be engaged with a single button.
- Gain improvements in fuel efficiency with auto-neutral idle.
- Haul your 770 truck at a more fuel-efficient engine speed and gear selection with speed limiting.
- Conserve fuel with integrated Engine Idle Shutdown by the engine automatically initiating when the truck is in park and idle for a preset amount of time.
DESIGNED FOR SAFETY
- DESIGNED FOR SAFETY
- Improvements in accessibility with safe, ground-level access tofuel fill and daily maintenance points.
- Ensure three points of contact when entering and exiting the machine with strategically placed walkways and grab rails.
- Superior brake performance meets the latest brake standards—
ISO 3450:2011. - The ground-level engine shut-off switch stops all fuel to the engine when activated and shuts down the machine safely.
- Sturdy 4-point mounted cabin meets rollover protective structure/
falling objects protective structure (ROPS/FOPS) standard. - 4-point seat belt provides enhanced safety to the operator.
- Seat belt indicator implements both visual and audible alerts to the
operator when seat belt is not fastened. - Lockout features help the service technician to perform
maintenance work on the machine with safe mode. - Secondary steering activates automatically in case of primary
system failure. - Overload speed limiter works with truck payload system to reduce
machine speed automatically when the truck is overloaded.

TECHNOLOGY THAT GETS WORK DONE
- TECHNOLOGY THAT GETS WORK DONE
- Integrated systems give you the ability to make timely, fact-based
decisions to maximize efficiency, improve productivity, and lower
costs. - Gain valuable insight into how your machine is performing by continuously
monitoring and collecting vital machine data via the advisor display with the software Vital Information Management System (VIMS™). Applicable to both U.S. EPA Tier 4 Final/EU Stage V and U.S. EPA Tier 2 equivalent. - Truck Production Management System (TPMS) provides accurate weighing of the materials, stores 2,400 payload cycles, and reportson, haul cycle times, and distances with date and time stamps.
- External payload indicator lights alert the loader when to stop, reducing the risk of machine overloading.
- Product Link™ system connects to each machine wirelessly,
allowing you to monitor location, hours, fuel use, productivity, idle
time, and diagnostic codes. - VisionLink®
wirelessly connects you to your equipment, giving
you access to essential information you need to know to run your business. - The Cat 770 is MineStar™ ready and includes Cat Product Link
Elite and VIMS to help optimize equipment management, remote
monitoring capabilities, machine availability, and component life while reducing both repair costs and the risk of catastrophic
failure. - Tons kilometers per hour/tons miles per hour (TKPH/TMPH) tire management system works with TPMS for improved tire life.
- Integrated systems give you the ability to make timely, fact-based
REDUCED MAINTENANCE COST AND OTHER COSTS
- REDUCED MAINTENANCE COST AND OTHER COSTS
• Grouped service points.
• Control particulate matter with two engine-mounted diesel
oxidation catalyst canisters. (Tier 4)
• NOx reduction system (NRS) technology replaces a portion of intake air with exhaust gas to control combustion temperatures and NOx production.(Tier 4)
• Parts commonality with other Cat equipment.
• Resolve problems before failure occurs with VIMS notifications.
• Torque converter stall (autostall) enables quick operating temperatures for best performance life.
• All LED lights provide longer life, brighter light, consume less power, and are more resistant to vibration or water damage.
APPLICATION VERSATILITY
- APPLICATION VERSATILITY
- Get the right body option—Dual Slope, Flat Floor, or Quarry—for your material and jobsite needs.
- For haul profiles including steep slopes, an optional Dual Slope body is available—offering excellent material retention.
- The flat floor body is perfect for metering material, especially when
feeding the crusher. - Optimize your body life by selecting a liner package best suited
for your application. We offer steel liners that work for most applications as well as rubber liners for extreme applications.
