To help users better cope with the harsh winter environment, this article shares maintenance and upkeep suggestions for excavators during the Great Snow solar term, covering aspects such as equipment storage, daily inspections, fluid management, startup and operation, and long-term parking.
I. Choose a Reasonable Storage Environment to Reduce the Impact of Low Temperatures and Snow Accumulation During the Great Snow solar term, excavators should be parked in dry, sheltered, and firm ground areas whenever possible. If conditions permit, it is recommended to park the equipment in a garage or simple shed to avoid prolonged exposure to wind, snow, and low temperatures.
If outdoor storage is unavoidable, pay attention to the following: Clear snow and ice from around the tracks or tires to prevent freezing and damage to the walking system; Use waterproof and snowproof equipment covers, focusing on protecting the engine, hydraulic system, and electrical components; Avoid prolonged parking in low-lying, water-prone areas to prevent freezing and damage to components.
II. Pre-Start Inspection is Crucial in Winter In low-temperature environments, metals contract, fluid viscosity increases, and the starting load on the equipment increases significantly. Before each startup, the following should be checked:
Battery status: Ensure sufficient charge, secure wiring, and no oxidation;
Fuel system: Use diesel fuel suitable for low-temperature environments to prevent waxing or blockage;
Hydraulic system: Check oil lines and joints for leaks, aging, or cracks;
Lubrication points: Ensure critical parts are adequately lubricated to avoid dry friction and wear.
These seemingly basic checks are especially important in winter, effectively preventing hidden damage to equipment caused by starting with faulty components.
III. Proper Fluid Management for Low-Temperature Operating Conditions
Winter is a high-risk period for fluid problems. As temperatures drop, the performance of engine oil, hydraulic oil, and coolant is significantly affected.
We recommend users:
Select engine oil and hydraulic oil of low-temperature specifications according to equipment requirements;
Regularly check the coolant freezing point to ensure its antifreeze performance meets local minimum temperature requirements;
Avoid mixing different types or brands of fluids to prevent performance degradation or sedimentation.
Good fluid management not only helps equipment start smoothly but also maintains stable operating performance in low-temperature environments.
IV. Standardize Preheating and Operation to Reduce Low-Temperature Wear
After starting the excavator during the Great Snow solar term, it is not advisable to immediately put it into high-load operation. It is recommended to first perform low-speed, no-load preheating operation to allow the engine and hydraulic system to gradually reach normal operating temperatures.
In actual operation, pay attention to the following:
Maintain smooth initial movements and avoid frequent, large-amplitude operations;
Minimize high-intensity digging or breaking operations when the machine is cold;
After operation, allow it to idle for a period of time before shutting it down.
These detailed operating procedures help reduce internal wear under low-temperature conditions and improve the overall stability of the machine.
V. Maintenance Recommendations for Long-Term Parking
If the equipment is parked for an extended period during winter, it is recommended to perform regular basic maintenance:
Start the equipment periodically to maintain the activity of the battery and hydraulic system;
Treat exposed metal parts for rust prevention;
Check the condition of seals to prevent cracking due to low-temperature aging.
Proper "winter hibernation management" can allow the equipment to quickly return to good working condition in the following construction season.
Conclusion
The Great Snow solar term is not only a turning point in the natural environment but also an important period for equipment management. Through scientific storage methods, standardized inspection procedures, and reasonable operating habits, excavators can maintain a stable and safe condition in frigid environments, laying a solid foundation for subsequent construction.
We consistently focus on the actual usage needs of equipment under different seasons and working conditions, and are committed to providing users with more reliable product support and more professional usage advice. In winter, attention to detail and proactive maintenance are crucial for efficient and worry-free operation.
