For Release Worldwide: September 2012
Release Number: 316PR12
Caterpillar announces the MT5300D AC 320-ton-capacity (290-tonne-capacity) mining truck as part of its ongoing investment in the Unit Rig™ products acquired through the acquisition of Bucyrus International. The new truck integrates a Cat® C175-16 engine and Cat 360T AC electric drive system with the proven Unit Rig MT Series trucks. The MT5300D AC takes its place in Caterpillar’s large mining truck product line between the 250-ton-capacity (227-tonne-capacity) 793F and the 360-ton-capacity (327-tonne-capacity) 795F AC.
The new truck builds on Unit Rig’s 50 years of electric-drive mining truck experience and the thousands of units currently working in mines around the world. The strength of the Cat engine and drive system combine with Cat dealer support and Unit Rig designs to deliver high performance and efficiency to mining customers. The MT5300D will be commercially available in the near future.
The MT5300D AC leverages Unit Rig’s millions of hours of field experience with the MT Series truck chassis, hydraulics, electrical system and suspension and integrates those systems with a proven Cat engine, AC drive and vehicle information management system. The Cat AC electric drive train is state-of-the-art, efficient and reliable, and has logged hundreds of thousands of hours in the lab and field, most notably in the 795F AC. The Cat electric drive truck program also leverages Electro-Motive Diesel’s (EMD) locomotive experience in design and manufacturing. EMD is a Caterpillar company, and the highly efficient system is Caterpillar designed, integrated and supported.
The MT5300D AC is designed to offer strong performance, safety, ease of operation and maintenance, and superior reliability. The Cat C175-16 is proven in Cat large mining trucks, and the Cat AC drive system features industry-leading dynamic retarding capacity combined with four-corner wet disc brakes. The system creates operator confidence that leads to productive and safe operation.
The ROPS cab, wide access stairways, traction control, and quiet radial retarder grid with wide right-side visibility enhance safety and further benefit the operator. Simple hydraulic systems, modular components, hydraulic gauge cabinet, grouped service locations, engine bay service walkways and more ground accessible maintenance points translate into less downtime and enhance safety for maintenance technicians.
Currently an MT5300D AC is being tested at the Caterpillar proving grounds in Arizona, USA.
