Regular maintenance of dump trucks
2019-12-04
1. Check the engine oil quantity of the dump truck
Park the dump truck on a level surface. Pull out the vernier scale to check the amount of engine oil. If the oil brightness is within the two marking lines (F) and (L), it belongs to the normal range, and if it is lower than the (L) position. Then add the specified type of engine oil, and the liquid level after refueling should not be higher than (F) position.
2.Dump truck engine coolant level inspection
When the dump truck engine is in a hot state, never open the radiator cover, otherwise it may be scalded by splashed coolant or high-temperature steam. After the engine cools down, check that the liquid level of the dump truck coolant should be between the full level and the low level, otherwise distilled water or purified water (no mineral water) or refrigerant should be added, and the liquid level after adding water should not exceed the full level. If it is found that the coolant decreases rapidly in a short period of time, check whether there is any leakage in the cooling system of the dump truck or go to the maintenance station for inspection.
3. Check the brake fluid level of the dump truck
If the brake of the dump truck is also between high and low, it means normal. If the brake fluid is close to the lower limit or lower than the lower limit, it means that there may be leakage in the system or excessive wear of the brake shoes, and it should be repaired at the service station in time. When adding brake fluid, pay attention to adding the same type of brake fluid to prevent damage to the cup, and pay attention to protecting the paint to prevent corrosion of the paint surface.
4. Inspection of liquid level of clutch master pump
If the clutch liquid level is between the high and low liquid levels, it is normal. If it is lower than the standard line, the master cylinder or the slave cylinder cup may be damaged. When the engine of the dump truck is running, it will be difficult or impossible to shift gears, please go to the nearest service station for inspection immediately.
5. Maintenance and inspection of dump truck batteries
Check whether the dump truck battery is firmly fixed, the electrolyte should be between the upper limit and the lower limit, and the electrolyte or distilled water should be added to the high line in time when it is close to the offline. Keep the positive and negative cables of the dump truck battery in good contact, and keep the battery clean and dry. For dump trucks that have been placed for a long time, the positive and negative cables of the battery should be removed, and after about half a month, reconnect and start the engine for about 20 minutes. If the power is obviously insufficient, it should be charged in time.
6. Inspection of dump truck tires
The tire pressure should be checked at room temperature every month. If it is lower than the normal standard, the tire pressure should be replenished in time. The air pressure cannot be too high or too low, otherwise it will affect the safety of driving. Check the cracks of the dump truck tires, and replace the tires in time if there are potential safety hazards. When choosing tires, the models should be consistent.
7. Belt inspection
When starting the dump truck engine or driving the vehicle normally, the belt sounds. One situation is that the belt has not been checked and adjusted for a long time, and it can be adjusted according to normal standards. Another situation is that the belt is aging and needs to be replaced.
8. Dump truck air filter inspection
If the air filter is too dirty, it will cause poor engine operation, excessive fuel consumption, damage to the engine, etc. When checking the air filter of the dump truck, if it is found that there is less dust and the blockage is lighter, you can use high-pressure air to blow it from the inside to the outside and continue to use it. Dirty air filters should be replaced in time.
9. Dump truck spark plug inspection
The insulating ceramics of normal spark plugs are intact. There is no rupture and leakage phenomenon, and when the spark plug gap is 0.8+-0.0mm to discharge, the spark of the dump truck is blue and strong. If abnormalities are found, adjust the gap or replace the spark plug.
