Overview

The Cat® 777 is engineered to be the industry’s most efficient 100-ton mechanical truck. With your input, we have designed and manufactured a reliable, durable, and economical truck, offering comfort, confidence, and control to its operators. With an improved access system designed to minimize slips and falls, this truck provides firm footing and stability in less-than-perfect conditions.

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.

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.

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.

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.

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™).

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)

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.

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.
