Komatsu 930E
Encyclopedia
The Komatsu 930E is an off-highway
, ultra class, rigid frame, two-axle
, diesel/AC
electric powertrain
haul truck designed and manufactured by Komatsu America Corp. 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 930E is the best selling ultra class haul truck in the world. As of March 1, 2010, Komatsu has sold 930 units of the various 930E models. The current models, the 930E-4 and 930E-4SE offer a payload capacity of up to 320 ST (290.3 t).
At the time of its introduction, the 930E was the world's largest, highest payload capacity regular production haul truck. The 930E remained the world's largest, highest payload capacity haul truck until the September, 1998 debut of the 360 short tons (326.6 t) payload capacity Caterpillar 797.
Prior to the introduction of the 930E, diesel/electric haul trucks employed DC
electric generators to power the traction motors at the rear wheels. The 930E was the first haul truck to employ an AC
electric alternator. The diesel/electric AC powertrain is more efficient, offers better operating characteristics and is more cost effective than a comparable DC powertrain.

, Komatsu debuted the 930E-2SE featuring a 3500 hp Komatsu SSDA18V170 V-18, twin-turbocharged, diesel engine developed by Industrial Power Alliance, a joint venture between Komatsu and Cummins. This is the same engine that powers the larger 360 ST (326.6 t) Komatsu 960E-1
and allows the 930E-2SE to operate at elevations up to 12000 ft (3,657.6 m) without deration. On December 15, 2003 Komatsu introduced the 930E-3, powered by a 2700 hp Komatsu SSDAl6V160 V-16 engine and a GDY106 traction motor on each side of the rear axle. The current models are the 930E-4 with a 2700 hp Komatsu SSDAl6V160 V-16 diesel engine and the 930E-4SE with a 3500 hp Komatsu SSDA18V170 V-18 diesel engine.
