Cat develops MT5300D AC for 320-ton-capacity
CATERPILLAR has developed the MT5300D AC 320-ton-capacity
(290-tonne) 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) 793F and the 360-toncapacity
(327-tonne) 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 fourcorner
wet disc brakes. The system creates operator confidence that leads

to productive and safe operation.
The gross machine weight is 505,755kg and the engine delivers 2750
or optional 3500 net horsepower (2050 or optional 2610 net kW).
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.
