With the arrival of summer.，There is more and more rain.，This makes the construction environment of Komatsu Excavator full of many challenges.。When the summer rains come.，Let's learn about the use and parking of Excavators in rainy season.“One, two, three”。
Careful inspection before construction is very important
1.Survey the construction area in advance。If the construction siteThere is too much waterOr there isTrapped carThe risk of，The construction should be cancelled immediately.，Wait until all risks are eliminated before continuing.。
2.Carry out all-round inspection of the Excavator。Before leaving the plane，First, check the tightness of the cab.，Prevent rainwater from entering the interior。Secondly, pay attention to the wear of the seal ring on the engine oil dipstick.，Then confirm that the excavator accessories include the filter element of the air pre-filter.、Whether the thread ends of the starter are loose or rusted，Handle the parts with problems in time.，Avoid the impact of moisture on the starter on subsequent operations.。Finally, check the use of the Generator.，All line joints shall be protected from moisture.，Affect the power generation effect。
3.Extend the warm-up time of the excavator engine。Because of the rainy days, the temperature is generally low.，Insufficient preheating time may cause damage to the oil pump or nozzle，Therefore, the excavator enginePreheatThe time should also be extended.。
Maintenance during construction in rainy season is particularly critical
1. Always beware of water in the power system.。It is the power system that is easily damaged in rainy days.，It may directly lead to the paralysis of the excavator.。When working in the water，Do not tilt the excavator more than15°，Prevent the upper part from being immersed in water，Do not exceed the centerline of the track carrier roller。Try to stop the machine before the water reaches the fan blade，So as not to damage the blades and the water tank。
2.If the excavator has a tendency to sink，Stop work in time。Upon discovery of subsidence，Find in timeSupport point，Use the big arm to support the Vehicle body，Prevent further subsidence。
3.Return to the original route as soon as possible after finishing the work.。When driving the excavator back, do notOther directionsDrive。At the same time, the front and rear headlights of the excavator should be determined during this period.、Work lights、Dome Light、Instrument lamp、Normal operation of wipers, etc.，To ensure driving safety.。
Downtime details are the secret of maintaining excavators in the rainy season
1.Remember to turn off the main power switch.。For excavators with computer control，In timePower line positiveTake it apart，Prevent serious damage caused by short circuit of the circuit when submerged by water.。
2.Pay attention to cleaning the excavator parts.。Thoroughly clean the chassis of the excavator，Wipe and maintain the necessary parts.;Check whether each oil drain screw is loose.;Wipe the place where the machine is found to have accumulated water in time，Prevent corrosion from affecting the normal operation of the machine。
3.Choose the right place to park。If there are conditions.，Try to park the excavator atIndoor dry place，If placed in the open air，The excavator shall face the direction of the water with the counterweight.，Also check that the fuel and hydraulic tank lids are tight，Avoid the loss caused by rainwater seeping into the oil tank。Finally, stay away from the possible.Landslide、The river is risingWait for the danger zone，Ensure sufficient fuel for the excavator，Can respond to environmental changes at any time，Initiate evacuation。
4.Pay attention to maintenance when the machine is stored for a long time。If the excavator is to be stored for a long period of time，The machine should be parkedGood drainageOn the concrete floor.，And cover it with waterproof cloth.。Try to start the engine and operate the machine on time once a month.，O as to lubricate the components.，At the same time, pay attention to charging the battery.，And the air conditioner is periodically turned on for refrigeration operation3-5 minutesMaintain the normal operation of equipment。
