The largest dump truck produced by Komatsu is the 980E-4. This dump truck has a payload capacity of up to 400 tons and can reach speeds of up to 64 km/h. It is equipped with a 3500 hp engine and has dimensions of 15.5 meters in length, 7.3 meters in height and 9.7 meters in width. The 980E-4 is used for transporting large volumes of rock, earth and other materials in quarries and construction sites. This dump truck is one of the largest and most powerful in the world and is widely used in the mining and construction industries.
The Komatsu 980E-4 dump truck consumes a minimum of 128 liters of fuel per hour of operation and a maximum of 307.3 liters. Its maximum speed is 61 km/h, and its turning radius is 15.9 meters. The weight of the machine without load is 255.868 tons and its gross weight is 625.277 tons with a nominal payload of 369.4 tons. The machine is 15,720 mm long, 10,010 mm wide and 8,000 mm high. The power at the flywheel of the engine is 2,495 kW and the total engine power is 2,610 kW. The fuel tank capacity is 5,300 liters.
The steering mechanism of the dump truck is equipped with double-acting hydraulic cylinders and a six-point articulated lever system. With this steering arrangement, the driver is required to make minimal effort to steer the dump truck. The turning radius of the machine is 15.9 m, which allows the machine to easily maneuver in loading and unloading operations of different complexity. The steering system uses hydraulic accumulators that comply with ISO-5010 standard. The integrated CENSE® system manages the engine and controls each of the 18 cylinders individually.
The machine features the Hydrair®II nitrogen-powered hydropneumatic suspension system. It includes four pneumatic-hydraulic cylinders. This arrangement provides the operator with a comfortable, smooth ride and thus ensures high productivity. The Hydrair®II suspension effectively absorbs vibrations and shocks to the machine chassis, which extends the life of the truck components and increases the durability of the frame.
The SENTINEL® oil condition monitoring system makes it possible to extend the life of the machine between oil changes up to 4000 engine hours. For this purpose, engine oil is added to the fuel system in an amount proportional to the volume of diesel fuel burned.
The Komatsu 980E-4 dump truck at mining companies reduces costs per tonne-kilometer of transported cargo. Expanding the fleet of such machines helps to increase the productivity of open pits and reduce the cost of transportation of mined ore.
