A batch of 100 XCMG 400kWh ultra-strong dump trucks has recently been handed over, bringing new green transport capacity to engineering projects spanning the high plateaus of Southwest China and the coastal regions of East China.
These vehicles will serve large-scale hydropower projects on the Southwest plateau and urban construction sites along the East China coast, undertaking earth and rock haulage tasks. Built to cope with harsh operating conditions ranging from cold, high-altitude plateaus to humid coastal environments, the XCMG 400kWh ultra-strong dump truck delivers outstanding load capacity, robust protection, powerful traction and low energy consumption to help customers unlock sustainable operational benefits.
All-Terrain Adaptability: Built to Tackle Diverse Environmental Challenges
On the Southwest plateau, the trucks will operate at local hydropower construction sites, hauling spoil and large rock fragments. The site features high altitude, low temperatures and sharp day-night temperature swings. Steep gradients, tight bends, narrow lanes and rough, uneven surfaces create extremely demanding haulage conditions.
Along the East China coast, the fleet has been delivered to a major urban construction client for muck and rock backfill removal, mostly for short-haul on-site transfers. The area sees sweltering summers and frequent rainfall, meaning vehicles operate continuously in hot, humid conditions.
The two sites represent starkly different environments — one dry and frigid, the other wet and hot. Even so, customers share identical core requirements: high uptime and minimal downtime to keep earth-moving schedules on track, alongside low energy use and reduced running costs to safeguard profit margins. Superior load capacity, strong power output, reliable sealing protection and energy efficiency are all essential, making the XCMG 400kWh ultra-strong dump truck the preferred choice.
Technology-Driven Performance: Multi-Layered Advantages for Efficient Operations
Earth and rock haulage involves long hours of fully loaded operation. The XCMG 400kWh ultra-strong dump truck is fitted with a 550kW high-power electric motor paired with a high-torque drive axle, delivering responsive, abundant power for fully loaded starts and long uphill climbs. Its chassis frame is reinforced with three layers of steel plate, combined with a straight V-rod balanced suspension, offering exceptional load-bearing capability and strong shock resistance on rough roads.
Dust and heavy rain pose constant threats to vehicle protection. The truck's three-electric system reaches the IP68 ingress protection rating, while the motor and electric controller meet IP6K9K standards. Critical components are well shielded against mud, water and fine dust.
Extreme cold and heat are major risks to stable battery and powertrain performance. The vehicle is equipped with an intelligent battery thermal management system, supporting reliable operation across an ultra-wide temperature range from -35°C to 65°C. Liquid cooling is applied to heat-generating core parts including the motor and gearbox, ensuring consistent and dependable power output even during high-temperature runs or long uphill climbs.
Energy consumption directly impacts operational profitability. A multi-stage energy recovery system intelligently adjusts regeneration intensity based on road conditions, recapturing energy during downhill travel and braking to cut overall power consumption.
XCMG Automobile continues to deepen its focus on new-energy construction transport. Through technological innovation, the brand breaks down environmental and operational constraints, delivering highly adaptable, high-value green transport solutions for efficient earth-and-rock haulage. Together with its partners, XCMG is advancing toward a low-carbon, high-efficiency and profitable future.
