What should you pay attention to when using an excavator?
As an important equipment in construction machinery, the operation and maintenance of excavators are directly related to construction efficiency and safety. Recently, there has been a lot of discussion on the use and maintenance of excavators across the Internet. This article will combine the hot topics in the past 10 days to sort out the key points that you need to pay attention to during the operation of the excavator, and provide structured data for reference.
1. Inspection items before operation
Before starting the excavator, a comprehensive inspection must be carried out to ensure that the equipment is in optimal condition. The following are some aspects that need to be focused on before proceeding:
| Check items | Things to note |
|---|---|
| Hydraulic oil | Check whether the oil level is within the standard range and whether the oil quality is clean |
| engine oil | Make sure the engine oil is sufficient and there are no leaks |
| coolant | Check whether the liquid level is normal and whether there are impurities |
| Tracks or tires | Check the wear condition and adjust the tension |
| Electrical system | Check whether lights and instruments are working properly |
2. Safety regulations during operation
Safety is the primary consideration during excavator operation. The following are the specifications that need to be strictly adhered to during operation:
| safety regulations | Detailed description |
|---|---|
| working environment | Make sure the work area is clear of obstacles and underground pipelines are marked |
| Operating posture | Maintain a stable posture and avoid sharp turns or stops |
| load limit | Overload operations are strictly prohibited to prevent equipment damage |
| personnel safety | Do not allow irrelevant personnel to approach during operations, and use signalmen to direct |
3. Daily maintenance and upkeep
Regular maintenance can extend the service life of the excavator and reduce the occurrence of failures. The following are the key points of daily maintenance:
| maintenance items | frequency | Specific operations |
|---|---|---|
| Lubrication system | every day | Add lubricating oil to each lubrication point |
| Filter inspection | weekly | Clean or replace air and fuel filters |
| Hydraulic system | per month | Check the hydraulic pipeline for leaks and replace the hydraulic oil |
| Engine maintenance | every 500 hours | Replace engine oil and oil filter |
4. Common faults and solutions
Some common faults may occur during the use of the excavator. Understanding how to deal with these faults can avoid downtime losses:
| Fault phenomenon | Possible reasons | Treatment method |
|---|---|---|
| Engine cannot start | Low battery, fuel system issues | Check battery voltage, clean fuel filter |
| Hydraulic system is weak | Insufficient hydraulic oil and pump wear | Replenish hydraulic oil and check pump pressure |
| Walking astray | Uneven track tension and hydraulic motor failure | Adjust track tension and check motor |
5. Things to note when purchasing a second-hand excavator
There has been a lot of discussion recently about second-hand excavator transactions. The following are the key points to pay attention to when purchasing second-hand equipment:
| Check items | Evaluation criteria |
|---|---|
| Equipment year | Prioritize equipment less than 5 years old |
| working hours | It is better to control it below 10,000 hours |
| Maintenance records | Request complete maintenance records |
| Test performance | Are all movements smooth and are there any abnormal noises? |
Through the above organized data, I believe you will have a clearer understanding of the use and maintenance of excavators. In daily work, be sure to strictly abide by operating procedures and perform regular maintenance to ensure efficient operation and safe operation of the excavator.
Recent hot topics also show that with the development of intelligent technology, more and more new excavators are equipped with functions such as GPS positioning and remote monitoring. These new technologies can help operators better manage equipment. It is recommended that qualified users consider upgrading their equipment to improve work efficiency.
