The 4476 kW 6,000 Hp retarding system provides state of the art braking capacity for navigating today’s mining applications which contain steep continuous descents and sharp switchbacks. Continuous retarding capacity enhances the productivity of the vehicle operator, while eliminating the need for excessive mechanical braking effort.
Invertex® AC control system offers independent control of the rear wheelmotors, which in turn provides outstanding traction-ability during wet and slippery conditions, thus improving tire wear and operator confidence. The air cooled Insulated Gate Bipolar Transistor (IGBT) inverter system technology provides the highest available reliability. The IGBT inverter is more compact and much simpler than the design of its predecessor, the Gate Turn Off (GTO) inverter, which improves serviceability and routine maintenance.
During slippery events caused by inclement weather conditions and/or application severity, the 960E wheel Spin-Slide prevention technology will detect and correct any wheel spin control events. Spin-Slide Control operates automatically and independently of the service brakes. During propulsion, "wheel slip control” reduces nonproductive wheel spin in low traction conditions. During retarding, "wheel slide control” prevents wheel lockup and subsequent sliding.
By using double acting hydraulic steering cylinders with a sixpoint articulation linkage, the 960E-2 power steering system provides steering control with minimal operator effort. The turning radius of the 960E-2 is 16 m 52' 6", which provides excellent maneuverability for tight loading and dumping conditions. The steering accumulators comply with ISO-5010 standards.
Hydrair II® is a suspension system that utilizes four nitrogen-over-oil cylinders. This suspension system is designed to maximize machine productivity by providing the operator with a smooth and comfortable ride. By absorbing shocks to the chassis during operation, Hydrair II® contributes to the durability of the machine’s frame and components.
The Komatsu 960E-2 cab design provides a comfortable and productive environment to meet today’s mining demands. The cab includes tinted windows, heating and air conditioning, acoustical insulation, double sealed doors, and provides filtered and pressurized air.
By using advanced computer-aided design, finite element analysis, and full-scale dynamic and static testing, the frame design has been structurally enhanced to carry 327 tonne 360 short tons and provides the highest reliability in the industry.
The GDY108 has a redundant brake and transmission fluid sealing arrangement for better reliability and an improved oil drain system for easier maintenance.
Although the dynamic retarding system is the primary braking force, the 960E-2 comes standard with four-wheel, hydraulically actuated, oil cooled service brakes. In the event that the truck’s hydraulic system pressure drops below an acceptable level, accumulator tanks will automatically apply all wheel brakes to bring the truck to a complete stop.
• Max. service apply pressure: 18960 kPa 2,750 psi
• Total friction area per brake: 103729 cm² 16,078 in²
The oil cooled brake system provides lower maintenance costs and higher reliability versus dry disc brakes. This system is fully sealed to help keep contaminants out and reduce brake wear and maintenance. The brakes are hydraulically actuated, removing all air from the design. By eliminating an air system, air bleeding is not required and water condensation that can lead to contamination, freezing, and corrosion is no longer present. There are three independent hydraulic circuits that provide hydraulic back-up.
The automatic lubrication system is designed to reduce downtime for lubrication by having a centralized location that automatically distributes grease to all lubrication points.
Recognizing that variation occurs naturally in material density, fill factors, and loading equipment, Komatsu America Corp. deems it necessary to establish a consistent payload policy. This payload policy is intended to identify the guidelines and limitations for the loading of Komatsu mining trucks, and is valid for approved applications and haul profiles only.
1) The average monthly payload must not exceed the rated payload of the truck
2) 90% of all loads must be below 110% of the rated payload of the truck
3) 10% of all loads may be between 110% and 120% of the rated payload of the truck
4) No single payload may exceed 120% of the rated payload of the truck
