The economics of surface mining require the highest production at the lowest lifetime cost per ton (CPT). By combining outstanding build quality with multiple features designed to improve fuel efficiency and reduce downtime, the new 4,400 hp (3,281 kW) Komatsu 980E-5SE electric drive 400 ton class mining truck the leading OEM says offers increased speed on grade in deep pit applications. The truck’s redesigned ergonomic automotive-style cab it says also works to increase operator comfort and lessen driving fatigue.
Leveraging Komatsu’s electric drive truck experience, the 980E-5SE in addition offers the highest-in-class horsepower available on an ultra-class truck. “Engineered to promote increased productivity and a reduced carbon footprint, the 980E-5SE’s electric drive means fewer mechanical components, less maintenance and potentially reduced life cycle costs.” This highest in class horsepower is delivered by a Cummins QSK95 engine, also known as the Komatsu SDA16V190-1 in this application.
When cycling through big loads, durability is key. The 980E-5SE was developed using advanced computer-aided design, finite element analysis and full-scale dynamic testing. Its truck frame is verified to carry a rated payload with the utmost structural reliability.
Automotive-style cruise control governing acceleration and deceleration helps operators maintain a constant speed while concentrating on steering and situational awareness. Traction control helps operators stay on task and operate more efficiently, even in slippery conditions. Wheel traction control technology detects and corrects wheel spin or slide events and engages automatically and independently of the service brakes.
To support increased production and optimised payload, Payload Meter IV (PLM IV) can help maximise cycle efficiency to reduce the machine’s life cycle costs. “Standard on Komatsu mining trucks, PLM IV tracks and records key production parameters, including payload weight, empty carry weight, haul cycle time, average speed and much more.”
