Trolley-Capable 860E-1K Joins Komatsu’s Fleet of Mining Trucks

Filed under: Berita — ahmadfaris @ 2:09 pm

Rolling Meadows, IL, September 22, 2008 — Komatsu America Corp. is pleased to announce the introduction of the new 860E-1K electric drive rigid frame dump truck. With a nominal payload of 254 metric tons (280 short tons) — and a factory installed trolley-capable option — the 860E will be the latest in a broad selection of fast and powerful mining trucks manufactured for distribution across the globe.


   Powerfully productive and environmentally sensible

The power plant in the 860E is the Komatsu SSDA16V160, a 2,700 HP, sixteen-cylinder, two-stage turbocharged diesel. To address the ecological impact, Komatsu designed the 860E’s engine to be Tier 2 certified.

Komatsu’s trolley system can be utilized on either 1,600 or 1,800 volt lines, allowing the 860E to propel uphill faster while the engine RPM reduces, thereby saving fuel and extending the life of the engine compared to non-trolley. In both applications, the Komatsu-designed drive system produces a maximum speed of 64.5 km/h (40 mph) with a 35.52:1 final gear ratio powered by the latest Siemens control package. The unique, liquid-cooled IGBT AC-drive system from Siemens provides advanced features and a smooth application of torque and traction.

Reinforcing Komatsu’s long-standing position as an industry leader in the development of powerful, environmentally sensible and diverse mining equipment, the 860E also offers outstanding braking power. An ultra-quiet dynamic retarding system, capable of 4,650 HP is assisted by 4-wheel wet-disc brakes. These braking elements, coupled with traction control technology, provide excellent braking force even in difficult road conditions.

   Operator comfort remains a key feature of Komatsu trucks

The 860E is designed to offer improved access systems which lead to the truck’s spacious, isolation mounted, ROP/FOPS certified cab. The cab features a deluxe, five-position adjustable air ride seat as well as a full size heavy duty passenger seat. The integrated electronic dash display provides a standard suite of instrument gauges as well as payload data.

To further enhance productivity and comfort during long shifts, the 860E’s steering column tilts and telescopes to customize the operator’s driving position. Automatic speed control for uphill or downhill hauling makes it easier for the operator to maintain a desired speed.

   Service and support are key

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 interface to easily check the pressures and trends, summarize yesterday’s payload, and be quickly alerted of critical faults.

As with all of the Komatsu electric drive mining trucks, the 860E is designed and manufactured at Komatsu America Corp’s Peoria Manufacturing Operation in Peoria, Illinois, USA. The truck has been tested at the Komatsu Proving Grounds in Arizona, as well as in field tests at customer. The 860E is slated for limited release in 2009 followed by full scale production in 2010.

The 860E has been designed with Komatsu’s industry-leading focus on quality: utilizing the latest technology developed from extensive experience in the field. Komatsu’s objective is to engineer products with a lower cost-per-ton. Komatsu recognizes that low cost-per-ton is a key to mining equipment selection and success for its customers.
