In the core scenario of mine transportation, 100-ton rigid dump trucks serve as the main equipment. Their power performance, reliability, and operating costs directly determine mine production capacity and profitability, and have always been the core criteria for users when selecting mining trucks. Traditional mining trucks mostly rely on a single high-horsepower diesel engine for driving, making it difficult to achieve an optimal balance between power output and energy consumption control. The Liugong DE100C rigid dump truck has pioneered a new dual-engine technology concept, innovatively equipped with two Cummins QSM15 diesel engines integrated with an extended-range electric drive system, redefining the power architecture and efficiency boundary of large mining trucks and realizing a two-way leap in power performance and operational efficiency.

 As the world's first 100-ton mining truck adopting dual-engine technology, the Liugong DE100C takes "two Cummins QSM15 diesel engines + motor extended-range electric drive direct-drive architecture" as its core. Relying on an intelligent control system to dynamically distribute loads, it enables coordinated driving of dual-engine power to achieve more precise energy efficiency management. Compared with traditional single-engine mining trucks, this power system not only completely solves the pain point of insufficient power under heavy-load conditions but also achieves a significant reduction in energy consumption and maintenance costs, providing a highly economical power solution for high-load mine operations.

As the core power source of the dual-engine system, the Cummins QSM15 diesel engine has been deeply optimized for harsh mine scenarios such as high dust, high altitude, and long-term heavy loads, laying a solid foundation for the efficient operation of mining trucks with its powerful and reliable performance. This diesel engine can output 563kW of power and 3000Nm of torque (at 1400rpm), with power increased by 30% compared to the previous National III product. Its outstanding low-speed and high-torque characteristics ensure a steady supply of power for mining trucks during steep slope starting and heavy-load climbing. Thanks to its modular design, the number of engine parts is greatly reduced. Combined with special accessories adapted to mine working conditions, it has excellent dust resistance and high-altitude adaptability, with stability and reliability far exceeding those of peer products, fundamentally improving the attendance rate of mining trucks.

 In terms of operating cost control, the Cummins QSM15 diesel engine demonstrates strong economy. Its advantages of no after-treatment device and urea-free operation significantly reduce consumable expenses and maintenance steps; its cycle-specific fuel consumption is 5%-15% lower than that of similar diesel engines. Cooperated with the dual-engine intelligent start-stop and load distribution strategy, the comprehensive fuel consumption of the Liugong DE100C is reduced by about 20%. At the same time, the coordinated optimization of the engine, motor, electronic control, hydraulic, and transmission systems reduces the maintenance cost of the entire power system by 50%. Coupled with the longer service life of core components, it significantly lowers the full-life cycle cost of mining trucks.

 Supported by Cummins dual-engine power, the Liugong DE100C has achieved comprehensive upgrades in productivity, safety, and comfort. With a rated load of 97 tons, a 63m³ large-capacity carriage, and a total power of up to 942kW, its slope transportation efficiency is 30% higher than that of traditional dump trucks, greatly shortening the operation cycle time. In terms of safety configuration, the 1200kW electric braking + dual-circuit braking system ensures the vehicle can stop stably on a 20% steep slope. It is equipped with a 360-degree camera and a FOPS/ROPS safety cab as standard. The one-key constant-speed downhill and stepless speed change functions not only improve operation safety but also reduce the driver's operation intensity, significantly enhancing riding comfort.

 Targeting complex mine working conditions, the Liugong DE100C further optimizes the frame structure and enhances the durability of key components. Matched with the high reliability of the Cummins QSM15 diesel engine, the vehicle has stronger adaptability to extreme operating environments. Verified by actual working conditions, this mining truck not only reduces energy consumption by 15%-20% and saves millions of yuan in full-life cycle operating costs but also breaks the industry pain point of "high energy consumption and high maintenance" of traditional mining trucks with a 50% reduction in maintenance and overhaul costs.

 From power output to efficiency control, and from reliability to economy, the in-depth integration of the Liugong DE100C and the Cummins QSM15 diesel engine provides a new path for the iteration of mine transportation equipment. This rigid dump truck, integrating high efficiency, safety, low consumption, and durability, breaks the performance bottleneck of traditional mining trucks through dual-engine power innovation, injects green and efficient momentum into harsh mine scenarios with core technologies, and becomes a core equipment driving the high-quality development of the mining industry with lower costs, higher reliability, and stronger productivity.
