Benefits

ACHIEVE GREATER PRODUCTIVITY

Haul your materials faster with an accelerated travel speed.
Put more power to the ground with an 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.

BOOST FUEL EFFICIENCY

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 777 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

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 cameras and radar systems to identify potential hazards.

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 a redesigned 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.
Advanced lighting with an LED lighting package.

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 777 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

Grouped service points.
Control particulate matter (PM) with two engine-mounted diesel oxidation catalyst canisters. (Tier 4 only)
NOx Reduction System (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 exhaust gas recirculation (EGR) coolers utilize flexible tubes to be more robust to cooling loss and more durable. (Tier 4 only)

APPLICATION VERSATILITY

A coal body option with 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.

DURABILITY

New C32B engine with integrated fuel lines (IFL) heads and dual sensor coolant protection (DSCP) for improved durability, temperature distribution, and structural robustness.
Improved transmission life and smooth shifting with APECS.
Autostall enables quick operating temperatures for best performance and life.
Delayed engine shutdown prevents hot shutdowns that can reduce component life.
