Komatsu 830E Dump Truck Service Manual A30689-A30707 VEHICLE/EQUIPMENT INTRODUCTION: The Komatsu 830E is an ultra-class rigid-frame haul truck designed for high-production surface mining operations. With a rated payload capacity of approximately 290 short tons, the 830E utilizes AC electric drive technology where a Komatsu SDA16V160 or SDA17V160 diesel engine drives an AC alternator which supplies power to two AC electric traction motors, one for each rear wheel. Eliminating the traditional mechanical transmission reduces maintenance and provides infinitely variable speed control with excellent retarding capability on downhill grades. The 830E features a robust welded steel box-section frame designed to withstand the extreme loads and shock impacts common in mining haul roads. This manual covers machines with serial numbers A30689 through A30707.
