CATERPILLAR LAUNCHES ELECTRIC-DRIVE 326- AND 372-TONNE MINING TRUCKS
Caterpillar has introduced two mining trucks, the 798 AC and the 796 AC. The electric-drive 798 AC features a 372-tonne (410-ton) payload and will join the fleet of over 1,000 Cat mechanical-drive 797s in the 400-short-ton class. The electric-drive 796 AC delivers 326-tonne (360-ton) payload and will be offered in all regions. The 795F AC, in the same size class, will continue to be offered in regions where engine emissions are less regulated. Both trucks will be available in the second quarter of 2019.
The design of the new trucks focuses on delivering class-leading payload, high reliability and simple serviceability. These attributes are built on the frame and chassis design proven in 18 million hours of legacy truck operation and now used by the Cat 794 AC.
The AC powertrain of each of the two new trucks draws from about 5 million hours of Cat
795 AC and Cat 794 AC truck operation. Cat AC electric drive is developed and manufactured by Caterpillar, the single source for the entire powertrain. The Cat C175-16 diesel engine powers both the new trucks. The engine can be configured to meet US EPA Tier 4 emissions regulations and offers a choice of 2610 kw (3,500 hp) or 2312 kw (3,100 hp).
The 796 AC and 798 AC are designed to minimize empty machine weight, as configured in the field. The design enables the 798 AC to carry its class-leading payload of 372 tonnes (410 tons) and to haul more material each cycle on 59/80R63 tires.
