Frozen weather construction is quite painful for excavator renters, and it also has a great impact on the operation of excavators. The following edition talks to them about winter excavator maintenance.
I. Excavator Fuel
The fluidity of diesel oil will deteriorate when it is cold and its viscosity will increase, which will easily cause engine failure. Therefore, diesel oil must be selected according to the local minimum temperature.
2. Excavator can't start
Eliminate other causes of failure, winter excavator can not start, there are the following common problems.
1. Battery power deficit
Winter is also very important for the maintenance of batteries. The safest way is to remove the batteries after work and store them in a cool and dry place.
2. Low turnaround
The low speed is mainly due to insufficient preheating, which is usually divided into two methods: air preheating and combustion chamber plug preheating. Before the excavator starts, it is usually preheated for 5-10 minutes before starting the excavator.
3. Cooling water is frozen
The problem can be avoided by discharging cooling water before it freezes. Running at idle speed before extinguishing, when the temperature of cooling water drops below 60 C, then extinguishing and releasing water, filling the discharged water with a barrel and putting it in the cab, it is also possible to add it the next day.
3. The wiper is frozen
Cover the wiper with cotton cloth before the rain and snow come. Even after the snow falls, it can be easily separated.
In addition, it is also a good way to turn on heating to remove fog, but long time heating is not conducive to people's respiratory tract, so it is necessary to ventilate regularly and clean the cab.
4. Slowing down of ice and snow ground operation
The ground covered with snow and ice is very slippery. When the machine is walking or operating, it should be very careful not to suddenly operate the control rod.
When the temperature rises after snow, the ground will become soft, which will easily cause the machine to overturn. More attention should be paid to it. Do not leave the shoulder of the road or fall into the snow, otherwise there will be the danger of overturning.
