China rated load 20 tons dump truck
In a dusty and rugged mining environment, an excellent dump truck is like a "steel camel", which must withstand heavy loads and extreme tests. Chongqing Cqwendy Engineering Vehicle combines the actual needs of mining to reveal the core advantages and scientific selection rules of engineering dump trucks.
Load king, double efficiency
The mining-specific dump truck is equipped with Yuchai 330 horsepower or more engine, with a reinforced cargo box and a multi-stage hydraulic lifting system, and the single-trip transportation volume can reach 25-50 tons, which is 40% more efficient than ordinary models. For example, after an iron mine adopted the Shaanxi Automobile Delong X3000 series, the average daily ore transportation volume exceeded 8,000 tons.
All-terrain survival expert
Pointed nose design + wet brake: cope with 30° steep slopes and gravel roads, shorten braking distance by 15%;
Double-layer stepped beam: anti-twisting ability increased by 60%, adapting to high-frequency vibrations on potholes;
Intelligent temperature control system: maintains stable output in an environment of -30℃ to 50℃, and reduces failure rate by 32%;
Long-term economic choice
Key components with modular design (such as Fast gearbox and Hande axle) reduce maintenance costs by 25%; the energy consumption cost per ton-kilometer of some electric models is only 1/3 of that of diesel vehicles, saving more than 200,000 yuan in fuel costs per year.
(1) Measure the load:
Mining areas with an annual output of more than 2 million tons: choose models above 30 tons;
Underground or narrow working surface: customize a 5-8 ton low-profile electric version;
(2) Verify the authenticity:
Check the matching degree between the vehicle announcement parameters and the mine qualifications, and pay special attention to "mine safety certification" and "off-road signs".
(3) Performance test:
Suppliers are required to provide:
8-hour continuous heavy-load climbing test video;
Hydraulic system 2,000 lifting durability report;
(4) Calculate TCO:
Compare the purchase cost, fuel consumption, maintenance, and residual value of the five-year use cycle. It is recommended to use the "Mining Vehicle TCO Calculator" tool.
(5) Service guarantee:
Preferentially select manufacturers with "mine area on-site service + spare parts sharing warehouse" to ensure 2-hour emergency response.
With the acceleration of smart mine construction, the new generation of dump trucks are integrating:
Unmanned driving system: centimeter-level positioning and fleet coordination and dispatch;
Hydrogen fuel power: zero emission and a range of more than 500 kilometers;
Digital twin maintenance: remote fault diagnosis through VR;
After a large copper mine in Inner Mongolia, China introduced an intelligent fleet, labor costs dropped by 45% and transportation dispatch efficiency increased by 60%, confirming the value of technological change.
