Komatsu America Corp. has unveiled the 980E-4 haul truck, for service in mine sites requiring 400-ton payload capacity.
With a 400-ton capacity and 3,500 HP engine, the 980E-4 builds on a long history of success with electric drive trucks, and reinforces Komatsu’s position as a global leader in the ultra-class mining truck market.
“For several years, many of our customers have been asking Komatsu for a 400-ton electric drive rear dump truck with the reliability of our flag ship model, the 930E. With the release of the 980E-4, we now have a product to meet this market demand,” said Tom Stedman, product manager at Komatsu America Corp.
“Building on the foundation of the 960E, Komatsu was able to expedite the development of this new truck, while maintaining our strict standards of design, testing and product quality. We have every confidence this new model will reliably deliver high productivity, considering Komatsu’s reputation for outstanding mechanical availability,” added Stedman.
The 980E-4 provides an optimal match in large-scale mining applications with big bucket shovels (55-99 yd3) — such as Komatsu’s PC8000 and the P&H 4100XPC–4800XPC, loading out in three to five passes, depending on bucket size and material density. This new truck features expanded dump body capabilities designed to optimize payload capacity and mining production.
Examples of 980-4 features designed to improve truck performance and lower cost per ton include:
• A powerful, 18-cylinder, Komatsu SSDA18V170 diesel engine, comparable to other trucks in the class for speed on grade, while maintaining a high stall-torque capacity for those mines with soft underfoot conditions.
• The engine comes standard with a pre-lube system, designed to help reduce wear during start-up, CENSE® on-board monitoring system and the ELIMINATOR® engine oil filtration system.
• The AC electric drive system, manufactured by GE Transportation Systems, enables efficient operations in both deep pit and soft underfoot operations.
• The Invertex II® drive system incorporates the latest AC technology and advanced performance features.
• The GDY108C traction motor was designed specifically for the 980E-4, with enhancements in both the mechanical and electrical portions of the motor.
• The 980E-4 uses the proven GTA-39 traction alternator, with millions of operating hours in both of Komatsu’s 930E-4SE and 960E-2 model trucks.
• The air cooled, insulated gate bipolar transistor (IGBT) inverter system technology provides high performance and greater reliability than past inverter technology.
Examples of the 980E-4’s improved vehicle control and handling include:
• An AC system that features an alternator designed with a dual impeller in-line blower (12,000 cfm air capacity), for consistent electrical component cooling, and a high capacity retarding package for longer brake life and improved horsepower for downhill descents.
• An electric dynamic retardation force of 6,000 HP, for continuous downhill hauling that allows the 980E-4 to maintain constant downhill speed or decelerate without frequent use of brakes. This permits travel at higher speeds — even down longer, steep slopes.
• An advanced traction and slip/slide management system that precisely controls the torque applied to each wheel independently. It is also engineered to reduce non-productive wheel spin in low-traction conditions.
• Similar logic is used during dynamic retarding for managing wheel lockup. These systems help provide exceptional vehicle control and handling, whether heading uphill or down.
Features designed to combat rugged conditions include:
• A continuous horse collar and ladder-type frame that continues Komatsu’s focus on engineering trucks with long-life and long-term reliability.
• Fabricated steel modules that join with high-strength castings designed to manage the dynamic forces created by a machine weighing 1,378,500 lbs. and carrying 400 tons of payload.
• A new dump body, incorporating high-tensile strength and abrasion-resistant steel. It gives the 980E-4 a rugged-chassis construction able to withstand the rigors of off-highway hauling.
• Custom body design offerings for a wide range of applications.
The 980E-4’s comfortable cab features ergonomic updates that include:
• An integral 4-post ROPS/FOPS structure
• Adjustable air suspension seat with lumbar support and arm rests
• A buddy seat
• Maximum R-value insulation
• Tilt and telescoping steering wheel
• Electric windshield wipers with washer
• Tinted safety glass power windows
• Komatsu PLM IV™ payload weighing system
• A 55,000 btu/hr heater and defroster, 21,600 btu/hr air conditioning (HFC – 134A refrigerant).
