Excavators, also known as digging machines, are earth-moving machines that use buckets to dig materials above or below the bearing surface, load them into transport vehicles or unload them into the yard. The materials excavated by excavators are mainly soil, coal, sediments and pre-loosened soil and rocks. Judging from the development of construction machinery in recent years, excavators have developed relatively rapidly, and excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of excavator are working weight (mass), engine power and bucket capacity.

Steps:

1. Excavators are fixed assets with large economic investment. In order to improve its service life and obtain greater economic benefits, the equipment must be staffed, scheduled and fixed, and the responsibilities must be clearly defined. When the post must be transferred, the equipment shall be disclosed.

2. After the excavator enters the construction site, the driver should first observe the geological conditions and surrounding environment of the working face, and there should be no obstacles within the rotating radius of the excavator to avoid scratching or damaging the vehicle.

3. After the machine is started, no one is allowed to stand on the bucket, shovel arm and crawler to ensure safe production.

4. When the excavator is working, it is forbidden for anyone to stay or walk within the radius of gyration or under the bucket. Non-drivers are not allowed to touch and touch the cab, and they are not allowed to bring training drivers to avoid damaging electrical equipment.

5. When the excavator moves, the driver should observe and whistle first, and then move, so as to avoid safety accidents caused by someone near the machine. After moving, the position should ensure that there is no obstacle in the space of the rotating radius of the excavator, and illegal operation is strictly prohibited.

6. After the work, the excavator should be moved away from the low-lying place or the edge of the geosyncline (ditch) and parked on the flat ground, and the doors and windows should be closed and locked.

7. The driver must do a good job in the daily maintenance, overhaul and maintenance of the equipment, and make a daily record of the use of the equipment. There is something wrong with the vehicle, so he can't work with illness and report for repair in time.

8. The cab must be clean, and the surface of the car body must be clean, free of dust and oil; Get into the habit of cleaning the car after work.

9. The driver should record the day shift in time, count the work content of the day, handle the odd jobs or zero items outside the project in time, and make a record of checkout.

10. Drivers are strictly forbidden to drink and drive after drinking at noon during working hours. If it is found, it will be given economic punishment and the economic losses caused will be borne by itself.

1 1. For man-made vehicle damage, it is necessary to analyze the causes, find out the problems, distinguish the responsibilities, and impose economic penalties according to the severity of the responsibilities.

12. We should establish a high sense of responsibility, ensure safe production, do a good job in communication and service with employers, do a good job in bilateral relations, establish a good work style, and work hard for the development and efficiency of enterprises.

13. Excavator operation is a special operation, and driving an excavator requires a special operation certificate.

14. Maintenance is a no-no for maintenance.
