Construction Equipment Guide

The largest of Komatsu’s full line of mining trucks, the 960E-1 (960E) AC electric drive haul truck, carries a 360-ton (327 t) payload and weighs 1,270,000 lbs. (576,062 kg) when fully loaded.

The 960E balances payload, productivity and power, and is designed to be the right match for today’s mining needs. Just over 24 ft. (7.3 m) tall, the 960E uses modern frame design and manufacturing technology to ensure the quality of this new truck. With more than three years of experience from coal fields to deep-pit copper mining, Komatsu has tested the 960E to be ready for today’s mining needs.

Komatsu America Corp. first introduced AC drive systems for ultra-class mining trucks in 1996 with the commercial production of the 930E. Today, the 930E has more than 650 units operating in the field.

The 960E was created with Komatsu heritage in electrical, hydraulic and service systems from the 930E. The 960E is powered by the Komatsu SSDA18V170 which uses a unique dual-stage turbo air handling system to deliver 3,500 hp (2,609 kW) with the lowest brake specific fuel consumption (BSFC) at rated horsepower for this truck class. This engine is matched to the power alternator and also is used on the 930E-SE, a high-power version of the 930E operating in North America, Chile and Australia with more than 250,000 hours of operation.

As a key part of any complete service and support program for its mining trucks, Komatsu installs the vehicle health monitoring system (VHMS) on every truck as standard equipment to allow easy access to summary performance data. Using a satellite communications system and optional wireless download, the Komatsu VHMS allows technicians to use a simple Internet web interface to easily check the pressures and trends, summarize the previous day’s payload, and be instantly alerted of critical faults.

The 960E’s cab offers added sound attenuation, dual air-suspension seats, and room for the operator’s coat and lunch. The updated dashboard includes simplified gauges and a unique display that combines payload and speed, conveniently providing the operator the information needed to operate the truck. The ergonomic layout and comfortable controls enable the operator to focus on productivity.
