Many places in the northern hemisphere are already feeling the chill of winter. At present, the impact of low temperature weather on equipment sho
uld be paid special attention to! The following will give you a comprehensive explanation of the precautions for using equipment in autumn and winter.
Things to note when using excavators in autumn and winter:
1. Warm up before starting
The excavator's engine and hydraulic system are all susceptible to low temperatures. Therefore, it should be fully preheated before each start, with a preheating time of at least 5 minutes, and ensure that the engine is running without load and the hydraulic system is preheated to an appropriate temperature.
2. Choose the appropriate fuel and oil
In low temperature environments, fuel and oil suitable for the local temperature should be used. For example, when the local temperature is lower than 4°C, a brand of fuel suitable for the local environment should be selected; in severely cold areas where the temperature is lower than -15°C, it is recommended to use 10W-30 engine oil and -45# antifreeze during maintenance. (Select based on working hours and ambient temperature)
3. Maintain the battery
When the temperature is low, the battery capacity will be affected. Therefore, in autumn and winter, when the equipment is not in use, the battery should be removed and stored in a warm room to avoid battery power loss. At the same time, regularly check the battery's power and charge it in time.
4. Keep equipment clean
When the temperature is low, moisture in the air can easily condense into frost or ice. Therefore, before using the excavator, you should check whether all parts of the equipment are clean and remove frost or ice in time.
Excavator maintenance precautions in autumn and winter
1. Check the hydraulic system
The hydraulic system is an important part of the excavator. During winter maintenance, you should check whether the hydraulic oil is sufficient, whether the hydraulic oil filter is clean, and whether the hydraulic oil pipe is broken or damaged. At the same time, the replacement of hydraulic oil should be carried out according to the actual situation.
2. Check the lubrication system
The lubrication system is very important for excavators. In autumn and winter, you should pay attention to check whether the grease is sufficient and whether the oil quality is good. At the same time, grease is regularly added as required to ensure the normal operation of each moving part.
3. Check the cooling system
Excavators are prone to cooling system failures in the low-temperature weather of autumn and winter. For example, if the coolant label is not up to standard, the water tank will freeze and other problems. Therefore, special attention should be paid to checking whether the various components of the cooling system are working properly in autumn and winter.
4. Check the walking and slewing systems
The traveling and swinging systems of the excavator are also one of the parts prone to failure. During maintenance, check whether all components of the traveling and swinging systems are working properly.
5. Timely maintenance
When the temperature is lower in winter, various parts of the equipment are more likely to malfunction. Therefore, if any abnormality is found in the equipment during use, repairs should be carried out in time. At the same time, the equipment should also be maintained and maintained in accordance with the maintenance plan required by the manufacturer.
6. Precautions for long-term storage
If the excavator will not be used for a long time, dust protection work should be done to prevent the freezing of dust and water from causing wear and tear on the machinery. It should be noted that the sludge on the machine should be rinsed clean before storage.
Precautions for use and maintenance of dump truck in autumn and winter
1. When parking, park on a stable and flat road surface, apply the parking brake and cover with triangular wooden stakes.
2. Drain water from the air reservoir to avoid air leakage from the frozen air valve. You can also add gas line antifreeze to the air reservoir.
3. Be sure to drain the water from the rear side of the mudguard before shutting down the filter to avoid freezing or waxing of the fuel.
4. The fuel label should not be lower than the lowest outside temperature to avoid waxing of the fuel after shutdown, making it difficult to start again.
5. The cargo box must not be in a lifted state for a long time to prevent the oil cylinder from rusting and the oil seal from aging and damage.
Dump truck operation and maintenance precautions in autumn and winter
1. Before starting, a comprehensive inspection of the entire machine should be carried out, focusing on checking the engine oil, antifreeze, air filter, etc.
2. Warm up the engine for 3-5 minutes after starting to avoid running at high speed after starting.
3. After starting, check whether the hydraulic lift, brake, and clutch are normal. Only if all checks are normal can the machine be operated.
4. The winter weather is cold and the roads are slippery. Pay attention to driving safety and avoid driving under the influence of alcohol.
5. Stop and idle for 3-5 minutes. The engine will form an oil film to avoid early wear of the engine.
6. Check the engine oil, antifreeze, and hydraulic oil during shift handover to ensure that the fluid levels are within the specified range.
7. Check the drive shaft bolts and tighten them promptly if they are loose; drain the air reservoir to prevent the air valve from freezing and damage.
8. Use HV winter hydraulic oil; the diesel grade should be higher than the outside temperature to avoid fuel wax formation.
