The new Cat® G Series represents a new era for this size class from Caterpillar. With your input, we’ve designed and manufactured a reliable and economical haul truck that offers comfort, confidence and control for your operators. Delivering a range of benefits including better performance with increased travel speeds, improved traction control and up to 13% lower fuel consumption with the Cat Utilising Adaptive Economy Mode that reduces fuel consumption while maintaining productivity, the Cat 777 is the industry-leading off-highway truck in this size class. Your long-term success is our goal; with G Series trucks, we're on the right road.

With improvements in torque, travel speeds and transmission controls, the 777G hauls materials faster and more efficiently than other dump trucks in this size class. This Cat truck puts more power to the ground with a 7% torque increase while the new transmission controls carry more torque through shifts, most notably on grades, and combined with increased 7th gear speeds deliver faster cycle times. Additionally, with a more responsive Traction Control System, the new G Series delivers a range of benefits when operating in wet and challenging conditions such determining slip or high speed turns, returning traction sooner and tyre wear reduction.  

As the comfort of your crew dictates their productivity and awareness on the work-site, the Cat 777 dump truck has been designed with operator comfort in safety in mind to help deliver a strong and predictable performance that enables your operators to achieve the lowest cost per ton. This Cat off-highway truck features easy, low-effort access to the cab and ergonomic, intuitive controls with a spacious sound-suppressed cab with large window areas to deliver excellent visibility and up to 50% decreased noise. Additional features with the Cat 777 dump truck include the Automatic Retarder Control (ARC) which reduces operator effort and controls braking on downhill grades and the steering-sensitive Traction Control System (TCS) that delivers  faster activation and improved response to wheel slip.
