Key points for driving an excavator: Crushing operation, normal working process, and parking precautions

1. Precautions for crushing operations

1. If the hammer cannot be driven into the crushed object smoothly, the crushing position must be changed in time. Do not continue to crush at the same position for more than one minute, otherwise it will not only accelerate the damage of the hammer, but also cause abnormal increase in oil temperature.

2. For hard objects, it is recommended to start from the edge and gradually crush them inward.

2. Work operation specifications

1. After the excavator enters the construction site, the driver should first carefully observe the geological conditions of the working surface and the surrounding environment. Make sure there are no obstacles within the rotation radius of the excavator to prevent the vehicle from being scratched or damaged.

2. After the machine is started, it is strictly forbidden for any person to stand in the bucket, on the shovel arm or on the crawler to ensure construction safety.

3. During the operation of the excavator, no one is allowed to stay or walk within the rotation radius or under the bucket. Non-drivers are not allowed to enter the cab and touch the operating equipment at will, nor are they allowed to lead the training drivers on the machine privately to avoid damage to the electrical equipment.
4. When the excavator is moved, the driver must first observe the surrounding situation and sound the horn to indicate, and then move the machine after confirming that it is safe to prevent safety accidents caused by people around the machine. After moving, make sure that there are no obstacles within the rotation radius of the excavator, and strictly prevent illegal operations.

III. Parking requirements
After the work is completed, the excavator should be driven away from the low-lying area or the edge of the trough (ditch), parked on a flat and solid ground, and the doors and windows should be closed and locked.

IV. Equipment maintenance and maintenance
1. The driver must do a good job of daily maintenance, inspection and maintenance of the equipment, and carefully fill in the daily record of equipment use. Once a problem is found in the vehicle, it is strictly forbidden to operate with a fault, and it should be reported in time and repaired.
2. Keep the cab clean and tidy, the surface of the vehicle body free of dust and oil, and develop a good habit of wiping the vehicle after work.

5. Work records and procedures
The driver should make daily shift records in a timely and accurate manner, and make detailed statistics on the work content of the day. For odd jobs or zero-item work outside the project, relevant procedures must be handled in a timely manner and records must be kept for subsequent settlement.

6. Work discipline
1. Drivers are strictly prohibited from drinking at noon during work, and are not allowed to drive after drinking. If violated, economic penalties will be imposed, and the economic losses caused by working after drinking will be borne by the person himself.
2. For vehicle damage caused by human factors, the cause must be analyzed in depth, the responsibility must be clearly identified, and corresponding economic penalties must be imposed according to the severity of the responsibility.

7. Personnel management and communication
1. As a high-value fixed asset, in order to extend its service life and obtain greater economic benefits, the excavator must implement a management system of fixed personnel, fixed machines, and fixed positions, and clarify the responsibilities of each position. If a job transfer is necessary, the equipment handover and briefing should be done well.
2. The driver must establish a high sense of responsibility to ensure safe production. Actively communicate and serve the construction party, build a good cooperative relationship, and show a good work style.

8. Special Warning: It is strictly forbidden to perform rotation and crushing actions at the same time during operation, it is forbidden to perform twisting operations after the hammer head is inserted into the crushed object, it is forbidden to use the hydraulic hammer horizontally or upwards, and it is even more forbidden to use the hydraulic hammer as a chisel.
