Power Train – Engine

The Cat® C15 engine with ACERT™ Technology uses advanced engine technology to reduce emissions without after-treatment. The turbocharged, aftercooled 6-cylinder engine has faster response for superior performance in demanding applications.

Power Train – Transmission

The Cat seven-speed power shift transmission matched with the Cat C15 engine with ACERT Technology provides constant power and efficiency over a wide operating speed range for optimal power train performance.

Structures

The 770 features a mild-steel, box-section type frame to deliver durability and long life with low operating costs. Castings and forgings are strategically placed in high-stress areas to evenly distribute stresses and provide long fatigue life.

Operator's Station

The 770 features an all new operator station with enhanced visibility, increased operator space and ergonomically designed controls that set new industry standards for operator comfort. All controls and gauges are positioned for optimum efficiency and total machine control.

Engine – Power Train Integration

The Cat Data Link electronically combines engine, transmission, brake and operational information to optimize overall truck performance. Stored diagnostic data can be accessed via the Cat Electronic Technician (Cat ET) service tool to improve troubleshooting and reduce downtime.

Brake System

Front dry disc and rear oil-cooled, multiple disc brakes are now hydraulically controlled, reducing maintenance costs and improving operator control and modulation. They provide exceptional, fade-resistant braking and retarding for maximum performance and productivity in all haul-road conditions.

Truck Body Systems

The 770 offers two body types with six different body liner system selections to accommodate almost any type of application. These body liner systems are designed to maximize strength and durability while providing the lowest cost per ton.

Information and Monitoring Systems

Standard on the 770, the Cat Messenger system provides real-time engine performance and operating data.

Safety

Caterpillar sets the standard when it comes to safety in the design and manufacturing of heavy equipment. Safety is not an afterthought at Caterpillar, but an integral part of all machine and systems designs.

Serviceability

The 770 offers 500-hour engine service intervals – 250 hours more than the 769D. Simplified service and maintenance features combined with improved service access are designed to reduce downtime.
