As temperatures gradually drop, especially in northern regions, the low temperatures of winter place higher demands on the performance and lifespan of used excavators. Proper winter maintenance not only improves equipment efficiency but also significantly extends its service life. This article will comprehensively analyze how to scientifically maintain used excavators in winter from multiple perspectives, helping construction companies and individual buyers avoid the risks brought by severe cold and enhance the user experience.
In winter, hydraulic oil viscosity increases and fluidity decreases, which can easily lead to system startup delays and even damage to the hydraulic pump.
Low temperatures can cause engine oil to become viscous and inadequate fuel atomization, resulting in difficult or even impossible starting.
For every 1°C drop in temperature, battery capacity decreases by approximately 1%. Frequent misstarts in winter are due to depleted or aged batteries.
After operating in high humidity or snowy conditions, tracks and other parts may become stuck due to accumulated snow and ice, affecting the machine's steering and movement.
Using hydraulic and engine oils suitable for low-temperature environments improves system responsiveness. Low-freezing-point hydraulic oil (such as L-HV low-temperature anti-wear hydraulic oil) is recommended in winter.
Check that all moving joints, such as the pins, boom, and slewing bearing, are properly lubricated. Replenish low-temperature grease promptly to avoid dry running.
Rubber components are prone to aging and hardening in low temperatures. Inspect hydraulic hoses for cracks or leaks.
Charge batteries regularly to maintain a sufficient charge. When parking at night, remove the battery and place it in a warm environment, or use a battery cover.
In winter, use "low-freezing-point diesel" (such as -10#, -20#, -35#) to prevent wax buildup and clogging.
The antifreeze in the cooling system must be replaced promptly, ensuring its freezing point is below the local winter temperature and maintaining a moderate level.
If equipped with an engine preheater or intake air heating system, ensure it is functioning properly to assist with cold-starting the engine.
Park the vehicle in a sheltered, dry environment, avoiding prolonged exposure to wind, snow, or humidity.
After the initial start-up in winter, the vehicle must idle for at least 5-10 minutes to allow the hydraulic system and engine to fully warm up before operation.
Initial operation should not be at full capacity. Intensity should be increased gradually to avoid system damage caused by "hot engine but not hot oil."
After daily operation, promptly clear ice and snow from the tracks, bucket, slewing platform, and other areas to prevent jamming and corrosion.
Inspection Items | Inspection Frequency | Maintenance Recommendations |
Hydraulic Oil Quality and Quantity | Weekly | Check the oil level and whether it is cloudy or thickened |
Engine Cold Start Performance | Daily | Check the ignition before starting. Preheat the engine, using a warm-up device |
Battery Voltage | Weekly | Measure with a voltmeter. If below 12V, charge and replace any aged batteries |
Antifreeze Freezing Point | Monthly | Replace antifreeze with an appropriate freezing point before winter to prevent radiator freezing |
Grease Filling | Weekly | Focus on movable joints such as the swing motor, bucket axle, and boom |
Track Clearing | Daily | Remove residual snow and ice immediately after operation to prevent seizure |
Diesel Filter | Monthly | Check for blockage. Replacement frequency should be increased in low-temperature conditions |
