If you have a lot of irregular operations on the excavator, it will directly affect the service life of your excavator.Today, I will tell you about the circumstances that are not suitable for excavation work, and remember the work that cannot be ignored.

1. The excavator starts to work when it is unstable.

The first wrong operation behavior: As shown in the above figure, the excavator starts to work under unstable conditions, and this behavior is not worth promoting. Because the frame of the working excavator will be repeatedly twisted and deformed, the frame will be cracked for a long time and the service life will be reduced.

The correct treatment under the above conditions is that, as shown in the figure, the entire mound is in front of the track of the excavator, so that the excavator is in a stable state, and normal operation can be performed.

2. The cylinder rod is telescopic to the limit for excavation work

The operation behavior of the second comparative injury excavator is as follows: as shown in the figure, the hydraulic cylinder of the excavator is telescoped to the end position for excavation operation. In this case, the working cylinder and the frame will generate a large load, and the tooth is Impact and impact of each axle pin may cause damage inside the cylinder and affect other hydraulic components.

3. The rear part of the track is floated for excavation work.

The third type of erroneous operation is to use the force of the upper part of the excavator body to carry out the excavation work. When the bucket and the rock are separated, the vehicle body will have a large load on the bucket, the counterweight, the frame, the slewing ring, etc., and it is easy to cause damage. The crawler lifting operation shown in the figure is very serious.

To put it simply, when the rear part of the crawler is lifted for excavation work, the total force of the oil pressure and the weight of the vehicle body acts on each pin shaft and its edge parts and the bucket, so that the working device is easily cracked. The fall of the crawler belt also has a large impact on the tail of the counterweight, which may cause deformation of the main frame, damage of the slewing bearing ring, and the like.

4. Use traction force to move large objects and do excavation work

Finally, I told you that the operation behavior of a wound digging machine is: when the excavator is working, using the traction force to move large objects and do excavation work (as shown in the above figure), work device, pin, frame, digging The bucket will have more force on it, affecting the life of these parts, so try not to do this.

Summary: Through the introduction of the third phase, we have a better understanding of the prohibited operation behavior of the excavator. I hope that everyone can use the correct operation mode when opening the excavator to reduce the damage to the excavator. Next, we will introduce the correct steps for root excavator work, swing work, and downhill work.
