Mine transport vehicle winter maintenance tips

Mine transport vehicle winter maintenance tips

At present, it has fully entered the winter, our mine owners must carry out regular inspection and maintenance of the vehicle, in order to ensure safe driving and improve work efficiency

1. Replace or add antifreeze in time. In winter, the outdoor temperature is very low, and the vehicle wants to operate normally, there must be enough antifreeze, otherwise the water tank is frozen, and the normal circulation is not possible, and the vehicle will fail. Antifreeze should be between MAX and MIX, less should be added in time, and it is prohibited to use untreated water as engine coolant.

2. Slow down careful driving: the braking distance of the mud road can reach three times that of the normal road, not to mention the snow road, the speed must be controlled, generally within 40-50km/h. If you are unfamiliar with the road, follow the path taken by the car in front.

3. Pay attention to the slope area: rain and snow weather slope will not be on the ground ice will lead to halfway skid, even if the air brake is dead, there will be landslide danger, must pay attention.

4. To prevent tire slippage: rain and snow on the ground friction weakened, do not hit the direction or sudden braking. Should take the form of point brake straight deceleration.

5. When necessary, large tonnage vehicles install anti-skid tire chain.

6. The vehicle operation should ensure that the air pressure reaches more than 7 mpa, and the gas storage tank should be drained in time. If the air pressure returns to zero, troubleshoot the problem in time. When hanging gear, step on the clutch to be in place, strictly prohibit the use of semi-clutch!

7. The use of hydraulic system, please stop the vehicle on the relatively flat road, put the neutral position before operation, step on the clutch pedal combined with the force switch! When it is necessary to lift the carriage, quickly turn the lifting handle to lift the carriage! The lifting handle should be released in time when the third section of the oil top of the container is raised. It is strictly forbidden to lift all the oil top without releasing the lifting handle!

8. Please release the hand brake in time when the vehicle is driving, and the hydraulic force extractor switch is separated! Four-wheel drive and high and low speed conversion should be in the neutral position to step on the clutch pedal operation, it is strictly prohibited to change during driving! In order to improve the service life of the four-wheel drive system, please use the rear wheel drive with no load, and it is strictly prohibited to use the four-wheel drive mode at high speed!

9. Heavy load driving with low speed mode to start, gently lift the clutch pedal, to avoid the vehicle violent rushing. When moving forward and backward, the vehicle stops first and then switches the gear, reducing the gear impact and improving the service time of the vehicle transmission system. Put the lever into neutral when stopping, pull the brake and turn off the main power switch! When the vehicle goes downhill, please lower the gear in advance to use the engine and transmission speed limit to avoid long-term braking, overheating of the brake system and brake failure! Heavy load uphill or steep slope driving in advance to convert high and low speed, high-speed rush is strictly prohibited! When switching between high and low speed and four-wheel drive, you need to step on the clutch.
