CR330E Mining Dump Truck

Key technologies

  1.Mature and advanced drive system, adaptable to various extreme operating conditions

  The AC electric drive system originates from the mature electric drive traction technology in the rail transit field. The control system, main generator, traction motor and reducer are independently developed by CRRC to ensure the maximum production efficiency. It is safe and reliable, with low fault rate and low maintenance cost. Based on the vibration load spectral induction of all road conditions and the fatigue equivalent acceleration model design, it can adapt to extreme operating conditions such as high altitude, wide operating temperature range, high-intensity vibration and slippery roads, with perfect functions and stable operation.

  2.Equipped with high-power engine, to bring about higher efficiency

  MTU 16V4000C23 3000HP engine can adapt to most existing mine conditions without de-rating at an altitude of 4,500m. The second generation of MTU high-pressure common rail fuel injection system is adopted, enabling better fuel economy. An engine monitoring system is installed to monitor the operating condition of each cylinder in real time, prolong the service life of the engine and reduce the use cost.

  3.High-strength frame, with better bearing capacity and longer service life

  It is subject to a box section design and welded with high-strength alloy steel plate, and features excellent welding performance and mechanical properties. The key bearing components are made of forgings and castings for a longer life.

  4.Reliable, efficient and accurate steering technology to reduce tire loss

  Electronic differential control technology: It follows the principle of deceleration while turning, keeps the steering angular velocity of the outer driving wheel unchanged, accurately calculates the speed of the inner driving wheel, uses PID algorithm to adjust the torque of the inner hub motor, and takes the signal of the rear wheel speed sensor as a feedback signal to realize reliable, efficient and accurate closed-loop control. It effectively improves steering stability and reduces tire loss and fuel consumption.

  5.Comfortable driving environment, and intelligent real-time monitoring

  The cab is provided with ROPS/FOPS features, which meet ISO3471 and ISO3449 standards for safety. It has large driving space and good tightness, provides a safe and comfortable driving environment, and is equipped with a real-time monitoring system to provide real-time operation data for each part of the truck.
