No.1:When the excavator is unstable, it starts to work：
A wrong operation behavior: the excavator began to operate in an unstable situation, which is not worth advocating. Because of the repeated distortion and deformation of the frame of the working excavator, the repeated operation of the frame for a long time will produce cracks and reduce the service life.
The correct treatment is to complete a mound in front of the track of the excavator, so that the excavator is in a stable state and can work normally.
No.2:The cylinder rod is stretched to the limit for crushing hammer operation:
The second kind of operation behavior of the excavator is: the hydraulic cylinder of the excavator is extended to the end position, and the digging operation is carried out. In this case, the working cylinder and the frame will produce a large load, and the impact of the bucket teeth and the impact of each shaft pin may cause the internal damage of the cylinder and affect other hydraulic components.
No.3:The back of the track floats for crushing hammer work;
The third wrong operation behavior is to use the force of the rear of the excavator body to carry out the crushing hammer operation. When the bucket and the rock are separated, the car body falls to the bucket, counterweight, frame, slewing support and other large load, it is easy to cause damage.
In brief, when the rear of the track floats to do digging operations, because the total force of the oil pressure and body weight act on the pins and their edge parts, the digging bucket, it is easy to cause cracking of the working device. The fall of the track will also have a greater impact on the tail of the counterweight, which may cause the deformation of the main frame, the damage of the rotary bearing ring, and so on.
No.4:Use the traction walking force to move large objects and do crushing hammer work:
Finally, I tell you that a kind of operation behavior of the excavator is: when the excavator is working with the breaking hammer, the walking traction force is used to move large objects and the breaking hammer drill rod is used as the crowbar operation, the working device, the pin, the frame, and the bucket will have a more powerful effect on the above, affecting the service life of these parts, so try not to do so.
Summary: We have a further understanding of the prohibited operation behavior of excavators, and hope that we can adopt the correct operation mode when opening excavators to reduce the damage to the excavators.
