Komatsu 930E Truck

The Komatsu 930E is an off-highway, ultra class, rigid frame, two-axle, diesel/AC electric powertrain haul truck designed and manufactured by Komatsu in Peoria, Illinois, United States. Although the 930E is neither Komatsu's largest nor highest payload capacity haul truck, Komatsu considers the 930E to be the flagship of their haul truck product line.

The Komatsu 930E Truck
The 930E is the best selling ultra class haul truck in the world. As of September 2016, Komatsu has sold 1,900 units of 930E. The current model, the 930E-5 offer a payload capacity of up to 320 short tons (290 t).

The 930E was the first two-axle, six tire haul truck to be offered with a payload capacity in excess of 300 short tons (272 t), making it the world's first regular production "ultra class" haul truck. The 930E remained the world's largest, highest payload capacity haul truck until the September, 1998 debut of the 360 short tons (330 t) payload capacity Caterpillar 797.

Prior to the introduction of the 930E, diesel/electric haul trucks employed AC from an electric alternator where it was rectified to power the DC traction motors at the rear wheels. The 930E was the first haul truck to employ two AC electric traction motors. The diesel/electric AC powertrain is more efficient, offers better operating characteristics and is more cost effective than a comparable DC powertrain. More details
