Brief introduction:
Mine heavy dump truck is used in open pit mines, can complete the task of rock earthwork stripping and ore transportation, work characteristics for short haul, bearing weight, commonly used large shovels or hydraulic shovels for loading, and back to the excavation point and unloading point.
Dump truck features:
1. Tall in appearance, it belongs to super-profile vehicle
Mine dump truck only in the limited mining area of driving, the size of the car is not limited, can be widened and increased the overall size of the vehicle, does not belong to the road car, can not be driven on the highway.
2. Large load and mass, strong power
This kind of vehicle weight between 20-360 tons, requires the engine must have high power and high torque, to ensure full load uphill easy and powerful, so this kind of vehicle is equipped with a high "specific torque" and high "torque increase coefficient" of engineering engine, the common speed is about 30-40km/h.
3. The frame
The frame is a special structure for construction machinery and vehicles, all of which are welded structure. The longitudinal beam adopts a closed box section.
4. The car
The carriage is also fully welded structure, bucket type floor rear warped, the bottom plate is made of high strength, high hardness of manganese steel welded, suitable for transportation under bad conditions and rough stone loading on engineering sites, to ensure the service life of more than 10 years.
5. Suspension
Adopt oil and gas suspension.
6. Vehicle steering system
Full hydraulic steering, equipped with emergency steering system, when the steering system power failure, the emergency steering system can ensure that it has a certain steering ability, so that the car parked in a relatively safe place.
7. The brake system
Equips with the auxiliary slow braking ability, when the braking starts, the engine exhaust braking first into work;
Then the hydraulic retarder or electric retarder together to join the retarder braking function.
8. The transmission system
With a load capacity of less than 100 tons, karmic mechanical transmission and traditional rear axle are adopted.
With a load of more than 100 tons, electric transmission is adopted: the engine drives the generator, and then the electric motor in the rear wheel is driven by current, so that the rear wheel drives the car.
9. Special tires
The tread pattern and structure of this kind of car tires are different from highway vehicles, which belong to engineering tires.
