Caterpillar Dump Trucks 12/02/2008

Caterpillar will be unveiling their expanded range of mine haul trucks that will include ac electric drive at MINExpo 2008. The Caterpillar articulated dump trucks are part of its range of off-highway mine haul trucks. The Caterpillar dump trucks will have added ac electric drive developed through a partnership with Mitsubishi Electric Corp. Mitsubishi Electric and Caterpillar will be showcasing two 200+ ton models at this years MINExpo in September. Going electric for Caterpillar is a definite departure from the conventional mechanical drives Cat uses throughout its mining truck range. The ac electric drive technology will be used alongside Caterpillars mechanical powertrain feature with an additional drivetrain option. Gerry Shaheen, Caterpillar group president said, This is the largest investment we have made in mining trucks in Caterpillar history and certainly demonstrates our commitment to maintaining a leadership position in the mining sector and serving the mining customer better than anyone in the industry.


So far the Caterpillar electric drive system has been installed for testing on the 797 haul truck with a 380 ton payload. The Caterpillar articulated dump trucks will initially be installed with the electric drivetrain in two truck models above the 200 ton range which will then be exhibited at the MINExpo International 2008. This is not the first electric drive truck in Caterpillars history. The Caterpillar dc-driven 779 truck, a 240 ton coal hauler, first came equipped with electric drive in the 1960s. Today more than half of the mine haul trucks used in the global mining industry are supplied by Caterpillar, which has its manufacturing facilities in Decatur, Ill. Shaheen said, Adding an electric drive to our lineup will enable Caterpillar to offer an additional solution to match customer needs.
