Water and land excavators are a very common type of equipment in engineering projects, as they carry heavy loads, which also accelerates equipment wear. Even with maintenance, some parts need to be frequently replaced. Next, let's discuss the knowledge of maintaining water and land excavators.

One, Lubrication Work: Bearings and chains are critical components of equipment with high operation frequency. Bearings typically require greasing once a month, and at least one major maintenance per year, with a thorough inspection of the internal structural components of the excavator. Bearings are generally replaced every 3-4 years, and actual conditions should be considered for assessment. Different brands of bearings may have variations in material; ensure product quality meets standards before determining the replacement frequency.

Section 2: Parts Replacement: The lifespan of parts for land and sea挖掘 machines can be affected by the region of use. The lifespan in coastal areas is significantly shorter than on land. Wear strips typically need to be replaced every 2,000 to 3,000 hours in normal conditions, but it's hard to estimate in coastal areas. Chain prices are generally high, with a replacement costing around 15,000. Of course, there are many different chain models, with larger sizes able to accommodate more complex environments.

The floor of an excavator is typically painted, but the protective paint is not very noticeable. Some important components include parts like the cutting spring steel plate, frame, and motor, which are not frequently replaced. They are still crucial parts that require attention during use.
