Tires

Note (2)
Caterpillar recommends the customer evaluate all job conditions and consult the tire manufacturer for proper tire selection.
Note (1)
Productive capabilities of the 775G truck are such that, under certain job conditions, TKPH (TMPH) capabilities of standard or optional tires could be exceeded and, therefore, limit production.

Sound

Sound Standards (3)
Hearing protection may be needed when operating with an open operator station and cab (when not properly maintained or doors/windows open) for extended periods or in a noisy environment.
Sound Standards (2)
The exterior sound pressure level for the standard machine measured at a distance of 15 m (49 ft) according to the test procedures specified in SAE J88:2008, mid?gear moving operation is 86 dB(A).
Sound Standards (1)
The operator Equivalent Sound Pressure Level (Leq) is 76 dB(A) when SAE J1166 FEB2008 is used to measure the value for an enclosed cab. This is a work cycle sound exposure level. The cab was properly installed and maintained. The test was conducted with t

ACHIEVE GREATER PRODUCTIVITY

ACHIEVE GREATER PRODUCTIVITY
  • Haul your materials faster with an accelerated travel speed.
  • Put more power to the ground with a 7% increase in torque.
  • Advanced Productivity Electronic Control Strategy (APECS)
  • Transmission controls carry more torque through the shifts, producing faster cycle times, most noticeably on grades.
  • Enjoy greater productivity while using a more responsive Traction Control System (TCS).
  • Reduce tire wear with maximum traction by engaging TCS early in the slip.
  • Strong, predictable performance helps operators achieve the lowest cost per ton.

Fuel Saving Strategies

New Brake Design

BOOST FUEL EFFICIENCY

BOOST FUEL EFFICIENCY
  • Up to 13% less fuel consumption.
  • APECS transmission controls increase fuel efficiency by maintaining momentum and speed on grade.
  • Automatically optimize fuel consumption with the Adaptive Economy mode – reduces fuel use without affecting productivity and can be engaged with a single button.
  • Find improvements in fuel efficiency with auto neutral idle.
  • Haul your 775 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 to fuel fill and daily maintenance points.
  • Ensure three points of contact when entering and exiting the machine with strategically placed walkways and grab rails.
  • Wet disc braking is standard on all four corners of the truck.
  • Ground-level refueling requires no climbing on the machine to fill the fuel tank.
  • The ground-level engine shutoff switch stops all fuel to the engine when activated and shuts down the machine safely.
  • Overload speed limiter works with truck payload system to reduce machine speed automatically when the truck is overloaded.
  • Four-point seat belt for operator and lap belt for trainer seat.
  • Four camera and radar system to identify potential hazards.

WORK IN COMFORT

WORK IN COMFORT
  • Completely redesigned cab for a whole new standard in visibility, comfort, and productivity.
  • The new operator seat placement provides easier operation and comfort to the operator.
  • Improvements in visibility gain enlarged views of the work area and its surroundings.
  • Access connectivity and decrease clutter with more storage areas with the new designed cab.
  • Enjoy the easy automotive-quality shifting with the new integrated hoist and transmission controls.
  • Automatic cab temperature controls.
  • Simplified operator interface with touchscreen display.
  • Best-in-class lighting with new LED lighting package.

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™).
  • Truck Production Management System (TPMS) provides accurate weighing of the materials, stores 2,400 payload cycles, and reports on weights, 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 775 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.

REDUCED MAINTENANCE COSTS AND OTHER COSTS

REDUCED MAINTENANCE COSTS AND OTHER COSTS
  • Grouped service points.
  • Control Particulate Matter (PM) with two engine-mounted diesel oxidation catalyst canisters. (Tier 4 only)
  • NRS technology replaces a portion of intake air with exhaust gas to control combustion temperatures and NOx production. (Tier 4 only)
  • Parts commonality with other Cat equipment.
  • Resolve problems before failure occurs with VIMS notifications.
  • Hydraulic oil filter life is extended to 1,000 hours under normal operating conditions.
  • Redesigned EGR coolers utilize flexible tubes to be more robust to cooling loss and more durable. (Tier 4 only)

APPLICATION VERSATILITY

APPLICATION VERSATILITY
  • A Coal body option of varying capacities is available for lightweight materials.
  • For haul profiles including steep slopes, an optional Dual Slope body is available—offering excellent material retention.
  • The X body’s flat floor is perfect for metering material, especially when feeding the crusher.
  • Protect your truck’s body life in high-impact, hard rock applications with the optional rubber liner—available for Dual Slope and X bodies.

SUSTAINABILITY

SUSTAINABILITY
  • The Cat® C27 engine meets U.S. EPA Tier 4 Final and EU Stage V emission standards.
  • The 775G emits up to 9% less CO2 than the previous 775F*.
  • Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels up to: 20% biodiesel FAME (fatty acid methyl ester) ** or 100% renewable diesel, HVO (hydrogenated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details.
  • Engine Idle Shutdown Timer reduces fuel burn, greenhouse gas emissions and unnecessary idle time by shutting down the machine after a pre-set idling period.
  • Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.
  • VisionLink® displays the CO2 emissions for monitored assets, calculated by fuel type for the Runtime Fuel Burned each day in a selected date range.
  • Don't waste fuel idling. Cat VisionLink® online fleet monitoring helps you manage idle time and reduce fuel burn and greenhouse gas emissions.
  • Take advantage of the Cat® Certified Rebuild program and return your end-of-life machines, systems and components to like-new condition. A Cat Certified Rebuild restores — and can even improve on — its original performance and productivity levels.

*All comparisons to 775F. Productivity, fuel and CO2 emissions vary by application. CO2 emissions calculations based on a reference work cycle using 2.2 U.S. gallons per hour of #2 U.S. diesel fuel based. Applies IPCC2006 methodology using U.S. EPA Emissions Hub emission factors. Includes DEF (diesel exhaust fluid) related CO2. Fuel measurements are at 15°C. Estimated average fuel consumption improvements are based on tests or Product Link® data where available. Productivity improvements are based on test data.
**Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel.
