Sinotruk HOWO 70T Mining Tipper Truck
Off-highway (mining) dump truck is a heavy-duty dump truck used in open-pit mines to complete the tasks of rock and earth stripping and ore transportation. Its working characteristics are short journey and heavy load. It is usually loaded with large electric shovel or hydraulic shovel To and from mining and discharge points. "Off-road" here does not have the meaning of off-road driving, but it is not allowed to drive on the road because of its wide shape and excessive total mass.

(1) The shape is particularly tall and belongs to a super-profile vehicle
Mining dump trucks only travel in a limited number of mining areas, and the size of the car is not limited. In order to increase the volume of each train, increase the volume of the carriage as much as possible, widen and increase the overall size of the vehicle, and its width is far beyond the country. The width of road vehicles specified in JTGB01-2003 "Technical Standards for Highway Engineering" and GB1589-2004 "External Dimensions, Axle Loads and Mass Limits of Road Vehicles" shall not exceed the limit of 2.5 meters, and they cannot be driven on highways.
(2) Large load quality and strong power of the dumper
At present, the load of this type of vehicle is between 20-360 tons, and it is still developing towards large-scale. Due to the large tonnage and the slope of the road, the engine must have high power and high torque to ensure easy and powerful when going uphill at full load. Therefore, these models are equipped with high "specific torque" and high "torque increase factor". Engineering engine. However, due to poor off-road conditions, the common speeds of these models are around 30-40km / h.
(3) Truck Frame
The frame is a special structure for construction machinery and vehicles, all of which are all welded structures. The longitudinal beam adopts a closed box section to ensure high torsional strength. The thick steel plates used are low alloy and high strength steel plates.
(4) Minning dump Truck compartment
The carriage is also a fully welded structure. The back of the shovel floor is tilted up, and the general slope angle is 12 degrees. There is no rear fence. Rough stone loading methods on transportation and engineering sites, and guarantee that their service life generally reaches more than 10 years. The latest generation of energy-saving body, represented by Australian technology, uses higher-strength alloy steel. Compared with traditional bodies, it reduces body weight by more than 20% and saves fuel by 8%. Reduce maintenance frequency by 30%.
(6) Truck Suspension
Off-highway (mining) dump trucks mostly use oil-gas suspension, especially for vehicles with a payload of 45 tons or more. This model with a short wheelbase and a particularly large mass is most suitable for the installation of an oil and gas suspension. It does not have the corresponding space to install the traditional leaf spring shock absorption. The front wheel's oil and gas spring cylinder also doubles as the steering pin, and the outer cylinder is fastened to the outside of the frame longitudinal beam, so the traditional integral front axle is omitted.
Due to the large mass of the vehicle and the large load on the front axle, the steering of the front wheels depends entirely on hydraulic power. In order to ensure safe and reliable steering, this type of vehicle not only uses full hydraulic steering, but also is equipped with an emergency steering system. When the power of the steering system fails, the emergency steering system can ensure that it has a certain steering ability, making the car park to a safer place. The place.
