1. Reduce impurities in the lengthening arm. When the external impurities enter the inside of the extension arm, many unnecessary hazards will be caused. For example, the surface of the extension arm is scratched, the lubricating oil film is damaged, and the parts are severely worn. But for the particularity of the work of the long arm, its working environment is complex and many things can not be avoided, so we should enhance the awareness of protection, choose the spacious and flat ground work as far as possible, do a good job of protection and strengthen the maintenance of the long arm to reduce the unnecessary harm caused by impurities;
2. To master the temperature. Different parts have different constant temperature. When the temperature exceeds this range, a series of adverse reactions will occur. Therefore, in daily work, it is also necessary to regularly clean the dust on the lengthening arm to ensure the smooth cooling air channel;
3. Avoid high load jobs. High load operation will have a serious impact on the boom, increasing its wear and tear. The failure rate of the boom in high load operation for a long time is much higher than that in normal load operation. Therefore, the reasonable distribution of the working load of construction machinery can extend the life of the extension arm and ensure its effective working ability;
4. Reduce corrosion. The phenomenon that the metal surface is damaged by chemical or electrochemical action with surrounding medium is called corrosion. This kind of corrosion will not only affect the normal operation of the mechanical surface equipment, but also corrode the parts inside the extension arm. For example, the chemicals in rainwater and air enter the inside of the extension arm through the external channels and gaps of the mechanical parts, corrode the inside of the mechanical parts, accelerate the wear of the extension arm, and increase the failure of the extension arm.
To a certain extent, the application of excavator's long arm solves the problem of limited working range of some excavators, and effectively improves the working efficiency of excavators. To a certain extent, the project quality has been improved, and the extension arm has gradually become an indispensable part of the project construction process, so the daily maintenance and maintenance of the extension arm is a very important part. Regular maintenance and cleaning of the extension arm can extend the service life of the extension arm.
