Electric excavators, as a kind of environmentally friendly and heavy equipment, have gradually replaced traditional fuel excavators and become the most used in many construction sites. However, any equipment needs daily maintenance and maintenance to ensure its normal operation and extend its service life. The maintenance of electric excavators is different from that of traditional machinery, especially in battery management, maintenance of electrical systems and inspection of conventional mechanical components.

The core of the electric excavator is the battery pack, and the maintenance of the battery is directly related to the performance and use time of the excavator. After the end of every day, timely charging is the key to maintain battery life, avoid excessive discharge or overcharging, excessive discharge will damage battery life, and overcharging may lead to battery heating and even safety risks. Therefore, the use of intelligent charging systems can effectively prevent the occurrence of these problems. In addition, it is important to keep the battery clean and dry, especially to avoid contact with water or oil, as these contaminants can cause the battery to short circuit or corrosion.

In addition to the battery, the electrical system of the electric excavator also needs to be checked regularly. Since electric excavators are primarily powered by electricity, the health of the electrical system is critical. Checking cables and connectors for wear, aging, or loosening is a non-negligible part of daily maintenance. Especially in the site where the construction environment is harsh, the cable may be vulnerable to external force pulling or damage. Ensuring that all electrical connections are tight can not only improve the efficiency of the electric excavator, but also reduce the incidence of equipment failure.

In addition, while electric excavators reduce the need for engine and fuel system maintenance, the maintenance of traditional mechanical components such as hydraulic systems, walking gear and working gear is still critical. Hydraulic oil is the core of the normal operation of the hydraulic system, and the regular replacement of hydraulic oil and filter can ensure the smooth operation of the hydraulic system and avoid the failure or loss caused by the decline in oil quality. For the walking device, the tightness of the track and the lubrication of the roller and the support wheel should be checked to avoid damage to the walking device caused by the track being too tight or too loose. In addition, regularly check the digging arm, bucket rod, bucket and other working devices to ensure that the connection parts are not loose or worn, and if necessary, add lubricating oil in time to reduce mechanical wear.

The cooling system of the electric excavator can not be ignored. Although the operating temperature of the motor is relatively low than that of the internal combustion engine, the temperature of the motor and battery pack may rise under long-term high-load operation. Therefore, regularly clean the dust and debris in the radiator and cooling system to ensure a good heat dissipation effect, which can effectively prevent the equipment from overheating. In addition, especially in the summer high temperature construction, it is particularly important to check whether the heat dissipation system is working properly.

Due to the less complexity of the fuel system, the noise and vibration are significantly reduced, but this does not mean that the overall cleaning and maintenance of the equipment can be ignored. In daily use, the outside of the electric excavator should be kept clean, especially the shell of the working device and the electrical system, to avoid dust and sediment accumulation affecting the operation of the equipment. At the same time, ensure that the electric excavator is parked in a dry and well-ventilated environment, especially in wet or extreme weather conditions, additional protective measures should be taken to prevent moisture or damage to equipment components.

In addition, during the operation, the habits of the operator also play a key role in the maintenance of the electric excavator. Smooth operation not only improves work efficiency, but also reduces wear and tear on equipment. In daily work, avoid high-load operation for a long time, and proper rest can avoid overheating of the motor and battery and extend the service life of the equipment. In addition, familiar with the operation manual of the equipment, in accordance with the specification of operation and maintenance, can also greatly reduce the occurrence of failures.

The advantage of electric excavators is that they are environmentally friendly and low-maintenance, but only if we need to maintain them carefully. By regularly checking the battery, electrical system, hydraulic system and cooling device, and keeping the equipment clean and lubricated, the electric excavator will be able to maintain operation for a long time.
