The
underground dump truck for mining, also known as underground dump truck, mining dump truck and mining transport vehicle, is a diesel-driven truck. The gearbox is converted into a hydraulic gearbox. It is mainly used in roadways with intact mining roads. The slope for transportation operations in metal mines and non-coal mines shall not exceed 25 degrees. Among the transport vehicles that often have climbing problems in underground mines, climbing transport vehicles can save more labor.
Heavy loads, especially the difficulties (including skidding) encountered by inexperienced new drivers in mining trucks. In such cases, do not start blindly to avoid damaging transmission system components such as clutch plates. In case of damage, the drivers of the four mining transport vehicles can step on the parking brake.
In the vehicle, use objects such as large stones and wedge-shaped pieces of wood placed behind the driving wheels, then slowly release the parking brake to check the vehicle. If there is no sign of rolling backward, restart the vehicle. This method reduces the difficulty of starting on slopes with medium loads and can usually achieve a smooth start.
Unlike heavy-duty vehicles climbing slopes (especially long and steep ones), drivers must select appropriate gears in advance and avoid environmental changes, especially for new drivers who lack driving experience. To stop, choose a relatively open area in advance.
When shifting gears, unlike transport vehicles, the vehicle must reach a higher speed. The shift must be timely and decisive. Otherwise, even if you shift, the speed may not increase sharply due to excessive engine stalling and increased load. Therefore, it is necessary to downshift, because insufficient power will be provided, which is not conducive to climbing again.
If the engine power is insufficient, it is necessary to downshift as soon as possible. Otherwise, even after the engine stalls severely, you may not be able to provide sufficient power for upshifting after downshifting. The gear shifting operation must be timely. If the joystick fails to move to the required gear, the driver must be ready to apply the brake to prevent the vehicle from “skidding” due to excessively long gear shifting time.
