Daily Maintenance of Excavators Under Three Working Conditions
Anyone who drives an excavator knows that if the daily maintenance of the machine is not paid attention to, the service life of the excavator will be greatly shortened and failures will occur frequently. The following is how to maintain the excavator in three common special working conditions.
- Swamp
When working in such an environment, first of all, ensure that the engine vent pipe is not bent or blocked. In addition, the frame must be cleaned after operation, and the lubrication conditions of the lubrication points everywhere, especially the rollers, must be checked. It will be very troublesome to wait until the mud on the fuselage is dry before cleaning. When walking, the mud at the walking device should also be removed first to prevent the floating oil seal from failing.
- Dusty environment
This kind of working condition is relatively common, and it will happen in many construction sites, but it should not be ignored. In daily maintenance, it is necessary to focus on cleaning the radiator to prevent it from clogging and causing the engine temperature to be too high. If the air conditioner is needed in summer and winter, then the air filter element needs to be cleaned so that the external circulation of the air conditioner is smooth. In addition, parts that are prone to dust, such as piston rods and dust seals, also need to be cleaned regularly.
- Rocky areas
Rocky conditions are the most likely to cause damage to components, so more care must be taken in maintenance. There are roughly five points that need to be paid attention to.
(1) Check the conditions of the track joints and rail chains of the track every day. If any damage or looseness is found, it needs to be dealt with or replaced immediately.
(2) Tighten loose bolts and nuts in time.
(3) During operation, the tension of the track should be slightly looser than usual.
(4) Regularly check the lubrication of the supporting wheels, driving wheels, drag chain wheels and guide wheels, and replenish butter in time.
(5) Pay attention to observation before walking. If you find a lot of gravel in front of you, you need to clean up the gravel before moving forward.
Therefore, we must pay more attention to details in our usual work, otherwise it will not only damage the machine, but also delay the construction period, which is not worth the candle.
