The chassis design was structurally improved through computational designs, element analysis and large-scale dynamic/static tests. This allows it to haul 290 tons or 320 short tons, the highest reliability in the market.
The 930E-4SE electric truck has a SSDA18V170 Komatsu diesel engine with 18 cylinders and a net flywheel power of 2,495 [kW] 3,346 [hp], providing an excellent productivity and performance in terms of fuel consumption.
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.
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.
This function provides a resistance of 5,400 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).
