As an excavator operator, the performance of the excavator in his hands is directly related to the ability to work in the engineering field, whether it can cope with all kinds of complex construction sites, to keep it in good condition, in fact, contains a wealth of learning and skills. The key lies in the maintenance, the following are the corresponding maintenance methods for different season.
1. Spring
In the spring, after the excavator has been stored for a long period of time during the winter, some fluids and materials may change and need to be checked comprehensively.
1. Check the fuel level of the excavator, and drain the fuel tank.
2. Check the excavator oil level and oil quality.
3. Check the excavator’s slewing reducer gear oil level and oil quality
4. Check the coolant level, and check whether there are cracks and water seepage in each water pipe.
5. Add grease to pins and lubrication points, and squeeze out the old oil from the oil ducts if necessary.
6. Check the tension of the fan belt and engine belt to see if they appear to be aging
7. Check the tension of the tracks
8. Check the tightness of the bolts
9. Check the operation of the inspection instrument.
2. Summer
In summer, there is a lot of rain and droughts, floods and mudslides occur frequently, so be careful:
1. When working, try to use small throttle, avoid too close to the edge of the cliff, ditch, if the ground in these places it soft, it is very easy because of the excavator’s own weight and vibration caused by the machine fall or fall off.
2. Pay attention to windproof, anti-collapse, moisture-proof and anti-slip when working in rainy season. Work in the rain always keep alert, night work should keep the excavator front and rear headlights,work lights, roof lights, instrument lights, wipers work properly to ensure safety.
3. After the rainy season operation must be cleaned on the excavator chassis, the necessary places for maintenance and refueling, in order to prevent rust and corrosion, check whether the screws are loose, timely maintenance, found that the chassis has a waterlogged place to be removed in a timely manner.
4. Summer also pay attention to check the excavator air filter element, to avoid the entry of rain, so that the paper filter element deterioration damage occurs clogging, timely replacement maintenance.
3. Autumn
Autumn is dry, fire safety awareness should not be slack, regular inspection and maintenance of the excavator, to prevent the problem before it occurs.
1. Check the engine, oil circuit and electrical system to see if there is any leakage or aging.
2. Clean the engine system in time to ensure that the engine is clean inside and outside.
3. Equip with a fire extinguisher. Most excavators are not equipped with fire extinguishers in the cab, resulting in a fire, the driver can not be the first time to save themselves, the excavator seriously burned, resulting in huge economic losses.
4. Winter
The lowering of temperature in winter requires a high level of oil and protection of the battery.
1. In winter, you should choose less viscosity, thinner and thicker grease, to change to low viscosity diesel fuel and engine oil.
2. After the temperature drops. the storage capacity of the battery will be reduced, this time should be covered with quilts and other clothing for the battery to keep warm, or disassembled and stored indoors, and then installed before the next day’s operations.
3. If the electrolyte level of the battery is found to be too low, distilled water or electrolyte should be added in the morning of the next day before work, not after the completion of the day to prevent freezing at night.
4. In cold winter, antifreeze should be added to the cooling system of the excavator, and the proportion of antifreeze added to the cooling system should be the proportion at the lowest temperature. If the excavator is to be parked for a period of time, the cooling water in the engine should be emptied.
