The 100-short ton carrying 777G offers 7% more torque and has a transmission that offers automotive quality shifts to help generate quicker haul cycles.

Along with the production boosts are fuel saving features such as configurable economy settings and an adaptive economy mode that automatically optimises fuel consumption based on the user’s production baseline.

An auto neutral idle and advanced productivity electronic control strategy transmission controls help make the truck more efficient when at idle in a forward gear and when climbing grades.

Customers also can choose to engage features such as engine idle shutdown and speed limiting to further improve fuel savings.

The 777G is also quieter than its 777F predecessor and produces fewer emissions.

It comes with Caterpillar’s US EPA tier 4 final solution – which comes two years in advance of the effective date of the regulation.

The solution includes engine technology combined with diesel oxidation catalysts.

As a result ultra-low sulfur diesel fuel and low-ash engine oil must be used. Other than that it requires no additional maintenance or operator input.

For operations outside US EPA-regulated areas, the 777G reduces emission with tier 2 or EU stage II equivalent technology and fuel efficiency.

Braking and traction control has been beefed up. Hydraulic oil-immersed disc brakes are standard on all corners of the truck.

Design updates extend brake component life by increasing the force used to disengage the brakes.

An optional Cat engine brake can extend service brake life and integrates with automatic retarder control, enabling fast downhill travel and reduced cycle times.

The 777G’s park brake system actuates the front as well as the rear brakes to better hold the truck on a slope.

Along with the brake performance updates, the 777G’s traction control can differentiate between tire spin and high speed turns so it can activate at lower speeds.

The system uses hydraulically applied service brakes for improved response time and modulation from one wheel group to the other.

On the safety front, object detection comes as standard.

Using a combination of radars, an in-cab display and multiple cameras, object detection provides equipment operators with enhanced awareness for increased site safety.

The 777G also offers tire monitoring through use of payload values from the truck production monitoring system and data such as air temperature and truck speed to calculate the load placed on tires.

As tires approach their load-speed rating, a warning is given and customers can choose what to do.

Service centres for both electrical connections and fluid fill are located at ground level.

An optional fluid fill center provides access to all fluids from a centralized location that includes a lighted keypad with level indicators showing what needs filling.

Additional fluid level monitoring is available to the operator in the cab.

Accessing the cab is easier. Hand rails promote three points of contact.

Inside the cab the operator experiences 50% less sound than they would in the previous model.

Behind the wheel sits a series III Cat comfort seat with vibration-reducing technology and a three-point restraint system.
