CR120EH Mining Dump Truck

Key technologies

  1.Distributed hybrid power energy recovery

  The power drive system mainly includes the engine, generator, power battery and drive motor. It is the power core of the vehicle. The power module of the engine + generator and the power battery jointly provide energy for all systems of the vehicle. Through the energy management system, the charging and discharging of the battery can be reasonably controlled to realize braking energy recovery and achieve the effect of saving energy.

  2.Modular and lightweight design

  The power module assembly, drive unit, electric wheel assembly and hydraulic system are of modular design, allowing for separate and rapid disassembly for repair, and improving the maintainability and attendance rate of the vehicle;

  Through finite element analysis of various typical operating conditions, the frame and carriage structure and appearance are optimized to realize lightweight of the vehicle.

  3.Efficient, energy-saving, reliable and sensitive steering and lifting technology for quick and stable unloading

  The steering system utilizes load-sensitive and constant-pressure variable control technology, ensuring that the steering control is both sensitive and reliable. The hydraulic lifting system employs high-speed power drive and confluence control, resulting in a rapid and smooth unloading process.

  4.Highly integrated electric wheel drive, offering powerful, reliable, efficient and energy-saving braking capacity

  The hydraulic drive utilizes motor speed regulation power drive technology, making the system both efficient and energy-saving. The vehicle drive utilizes a highly integrated electric wheel assembly, allowing all wheels to provide braking force for the vehicle. This force is reasonably distributed to enhance the vehicle's braking capacity and ensure safety.

  5.Excellent structural performance of frame provided by cast-welded combination design

  The frame features a cast-welded combined box section structure, with key stress points designed as a cast structure to enhance strength and fatigue resistance, prevent stress concentration at the welds, and ultimately improve the reliability and service life of the frame.

  6.U-shaped structure allowing for thorough unloading

  The carriage features a welded structure with lightweight design, and both sides of the bottom plate are of "U"-shaped structure, which reduces the overall weight of the carriage and prevents the adhesion and retention of goods in the bottom corner, allowing for more thorough dumping.

  7.Reliable hydraulic system for quick response in steering, braking and lifting

  The hydraulic steering system features sensitive steering and a large-flow amplifier to control the steering cylinder to enable both front-wheel steering and four-wheel steering. The power source employs a constant-pressure control variable plunger pump, ensuring rapid steering response;

  The hydraulic brake system is equipped with an electric proportional large-flow brake relay valve to improve the flow performance of oil, thereby quickly providing braking pressure and improving the braking response speed;

  The lifting system is provided with lifting power by the combination of the steering pump and lifting pump, enabling rapid lifting.

  8.Intelligent driving system and refined interior design

  The cab interior features a modern design with a high level of refinement, achieving a noise level of ≤ 76 dB to enhance overall driving comfort. It is equipped with an LCD instrument panel and an adjustable multifunctional steering wheel, facilitating precise control and efficient operation. Optional features include cruise control, an electronic monitoring system, an anti-collision warning system, and a millimeter-wave radar anti-collision system, all of which enhance driving safety and operational efficiency, providing comprehensive technical support for mine transportation.
