The chassis design was structurally improved through computational designs, element analysis and large-scale dynamic/static tests. This allows it to haul 181 tons or 200 short tons, the highest reliability in the market.
The 1,405 [kW] 1,884 [hp] Komatsu SSDA16V159E-2 engine of the 730E-8 has stronger features due to the incorporation of the latest technology. An improved fuel system with updated components reduces noise and vibration levels for a better reliability and performance. Complies with US EPA. Tier 2.
The KOMTRAX Plus system allows the machine to monitor the status of main components, remotely evaluating their condition and operation. This system was designed to reduce repair costs and to keep an ideal availability by preventing unscheduled downtimes.
In summary, the clearest advantage of this system is that, by using it appropriately, a proper operation and maintenance can be achieved, maximizing its performance and extending its service life.
This function provides a resistance of 3,700 HP, with an advanced braking capacity for mining applications with continuous downhills, and steep and closed curves. This feature uses electricity to stop the equipment, which is dissipated through a grid and transforming it into heat. The use of electricity instead of mechanical energy, means the equipment uses a cleaner, more efficient energy which reduces the operation, maintenance and availability costs of the equipment. The electric dynamic retarder improves productivity and the operator’s reliability, while eliminating excessive mechanical braking efforts (less wear and more energy efficiency).
While on drive retard, the operator can select a traveling speed smoothly. The automatic speed control manages simultaneously the speed of each wheel to perform immediate adjustment during slippery conditions.
Hydrair II® is a suspension system with four nitrogen-over-oil cylinders. This suspension system is designed to maximize the machine’s productivity, providing the operator with a smooth and comfortable drive.
By absorbing the impacts in the chassis during operation, the Hydrair II® system helps improve the machine’s frame and components durability.
The electric drive system, in comparison with the mechanical drive, allows for an efficient and cleaner movement. By excluding almost all mechanical structure elements, this system reduces scheduled maintenance intervals and corrective repairs, and, therefore, reduces operating and maintenance costs. The latter also means an important rise in the availability rate and in the equipment’s production. Its drive curves show an operating efficiency beyond comparison.
