For increased productivity and performance in mining applications, Komatsu America Corp. (KAC) introduces the new HD1500-7 mining truck to both its North American and international mining customers. The truck is available at Power Motive Corporation’s five locations in Colorado. This machine includes significant enhancements in its drive train, cab and frame, building on the proven reliability and reputation of Komatsu mining trucks. Powered by a turbocharged Komatsu SDA12V160 engine, the HD1500-7 has a nominal payload of 158 U.S. tons (43.3 metric tons) and delivers 1487 HP (1109 kW) at 1900 RPM. The optional SDA16V159 engine offers North American customers an EPA, Tier 2 certified engine, making the HD1500-7 the first truck in its class to offer a Tier 2 certified power plant. Considering the incorporation of VHMS with integrated Payload Meter as standard equipment, the new HD1500-7 offers owners and operators a state-ofthe- art system for monitoring both the application and performance of this haul truck.
Power plant The Komatsu SDA12V160, 12 cylinder, turbocharged diesel engine provides proven reliability while incorporating today’s latest technology. The engine’s CENTRY™ electric engine management system continuously monitors engine conditions and automatically adjusts for peak operation. A pre-lube system eliminates wear from both cold and hot starts for longer engine life. The optional CENSE™ engine diagnostic system is integrated with VHMS and provides real-time data for maintenance and operations personnel.
For North American customers, an optional Komatsu SDA16V160 engine conforms to all EPA regulations for Tier 2 emission controls while providing a smooth & reliable power delivery to the truck systems.
Drive system As compared to the previous model, the HD1500-7 will feature an enhanced engine damper assembly, driving the reliable Komatsu seven-speed, electronically controlled transmission. Both the front and rear propulsion shafts have been redesigned to provide a smooth transition of power to the updated final drive assembly. The final drive housing is cast with 55,000 lb (24948 kg) yield strength material and has been recontoured to more effectively reduce stresses on the drive components. The final drive features planetary gear teeth with a larger profile and the internal drive shaft diameter has been increased to match the torque requirements of the drive train. Performance
Compared to its mechanical drive competition, the HD1500-7 has over 4% more horsepower, providing a 10% speed advantage on an effective twelve percent grade at maximum GVW. Downhill, the difference is even greater, with the HD1500-7 providing an 18% speed-on-grade advantage while traversing a negative ten percent effective grade, fully loaded. In addition, the HD1500-7 has the tightest turning diameter in its class, a full 10 feet (3.05 meters) less than the competition. These distinct differences between the new HD1500-7 and other trucks in its weight class translate to shorter cycle times, greater hauling efficiency, and a lower cost per ton.
Parts interchangeability drives success The new HD1500-7 has been designed to standardize many components with existing 530M/HD1500-5 mining trucks. This effort to make many components common between models gives access to an existing pool of new & remanufactured parts inventory to help maintain their new HD1500-7. Service technicians can build on their experience with existing models. Additional training is available at Komatsu’s world class Training and Demonstration Facility in Cartersville, GA. Some of these common items include: • Rim assemblies • Front and rear suspensions • Hoist cylinders • Dump body • Engine assembly including the radiator (SDA12V160 only) • Fuel tank/hydraulic tank • Most consumable items, (filters, belts & hoses)
Optional Equipment The new HD1500-7 will be available with many of the same options that have proven to be valuable to existing Komatsu rear dump truck owners. These include: • Komatsu SDA16V159 engine for EPA Tier 2 certified applications • Arctic protection package • Hot starts (engine oil, coolant, hydraulic tank) • Deck-mounted mufflers • Disabled truck quick disconnects • Pressure fueling – remote LH
