Performances
The components of the powertrain are designed and manufactured by Caterpillar to work together and form a system in the 770G. C15 CAT® Engine The C15 ACERT Cat diesel engine has proven itself for construction applications and highway trucks in North America. The C15 offers: A net power of 360 kW (483 hp) at a speed of 1,800 rpm. Maximum power available up to 3,000 m (9,842 ft). A robust gray cast iron engine block with ribbing for optimal strength. Six one-piece steel pistons with steel skirts to control thermal expansion. Pendulum dampers on the single overhead camshaft to reduce noise and vibrations. Cylinders made of graphite and compacted steel to ensure long life and tight tolerances for combustion quality. A water-cooled turbocharger with a boost pressure limiter equipped with a titanium impeller to ensure long life at high speeds. The fuel circuit is mechanically operated but electronically controlled (MEUI™). It quickly adapts to changes in load and injects extremely fine fuel particles to provide optimal combustion quality and energy efficiency. Low-temperature idle management automatically adjusts the engine speed to maintain optimal operating temperatures.
Fuel-saving strategies
Standard Economy Mode A switch located inside the cabin allows the driver to activate this mode. This mode reduces the engine power. Customers can change the power of the dump truck from 0.5 to 15 percent to save fuel.
Braking performance
Cat dump trucks are characterized by robust and reliable braking performance. The design principle is based on long life and excellent performance in quarries, mines, and construction sites.
Dumpsters
Caterpillar offers bucket options suitable for most types of material and applications. The mild steel body undercarriage helps neutralize the load and allows for simple repairs involving welding.
Structures
Chassis Cat dump trucks are renowned throughout the industry for their reliable and durable chassis. These chassis are built to perform on construction sites and off-road. Caterpillar uses molded parts in areas exposed to high stress and a box construction to handle torsional loads. The chassis are welded on a 360-degree rotating platform, which allows for consistent welds with deep penetration. Each chassis undergoes quality and compliance testing prior to assembly.
Information and monitoring
Advisor Screen and Cat Indicators The Cat indicator block is standard in the cabin. It displays real-time operating data and machine performance. An optional Advisor screen allows for better communication with or from the dump truck.
Simple interview
The Cat G series dump truck is designed to provide drivers and technicians with easy access to common maintenance points such as the engine lock control, machine circuit lock control, liquid level gauges, grease fittings, and engine access for regular scheduled maintenance. Most of the liquid level gauges are visible from the ground. The engine oil and engine oil filter must be replaced every 500 hours under normal operating conditions. The hydraulic filters have a lifespan of 1,000 hours under normal operating conditions. VIMS trend analysis allows for monitoring the condition and operation of the machine. The brake wear indicator is standard. The automatic lubrication system is available as an option. The fuses and circuit breakers are easily accessible and arranged to facilitate maintenance. The radiator and cooling bundles are made of aluminum and are modular, making cleaning or replacement easier. Sampling ports allow for quick and clean collection of oil samples for analysis purposes. The fuel circuit is equipped with an electric priming system. The quick fuel filling device is optional.
