Mining dump truck of Howo is a kind of heavy dump truck used in the open pit mine to complete the task of rock and earth stripping and ore transportation. Its working characteristics are short transportation distance and heavy load. It is usually loaded by large electric shovel or hydraulic shovel, and it goes back and forth to the mining point and ore unloading point. The "off-road" here does not mean off-road driving, but only because its appearance is too wide and its total mass is too large, it is not allowed to drive on the road.
Mining dump truck of Howo has a very tall appearance and belongs to super profile vehicle。The mining dump truck only runs in a limited mining area, and the overall dimensions of the truck are not limited. In order to improve the transportation volume of each car, increase the volume of the car as much as possible, widen and heighten the overall dimension of the truck.
Mining dumper has heavy load, powerful power.At present, the load of this kind of vehicle is 50 tons, and it is still developing towards large-scale. Due to the large load tonnage and many slopes on the road, the engine must have high power and high torque to ensure that it is also easy and powerful when it is loaded uphill. Therefore, all these models are equipped with engineering engines with high "specific torque" and high "torque increase coefficient". However, due to the poor off-road working conditions, the commonly used speed of these vehicles is about 30-40km / h.
Mining dump truck wheelbase and total length should be shortened to shorten the loading and unloading area of the mining area. The area of loading and unloading points is narrow and the turning and reversing are frequent. The roads in the mining area are mostly temporary roads, and there are many up and down slopes and sharp turns in the mountain area. In order to keep the mobility and flexibility, the wheelbase and total length should be shortened to reduce the turning radius and the number of reversing. Therefore, the 2-axis 4 × 2 structure is basically adopted to ensure the simple structure of the chassis and the convenient maintenance, Steering flexibility.

Mining dump truck of Howo's frame is a special structure for construction machinery vehicles, all of which are fully welded. The longitudinal beam adopts closed box section to ensure high torsional strength. The thick steel plates used are low alloy and high-strength steel plates.
Mining dump truck of Howo's carriage is also a fully welded structure, with the back of the bucket type floor cocked up, with a general slope angle of 12 degrees, and no rear baffle; the bottom plate is welded by high-quality steel plates with high strength, high hardness and impact resistance to adapt to the transportation of non highway and poor mining industry and rough stone loading on the project site, and its service life is generally more than 10 years. The latest generation of energy-saving body represented by Australian technology adopts higher strength alloy steel. Compared with the traditional body, it reduces the weight of the body by more than 20% and saves 8% oil. 30% reduction in maintenance frequency.
