Professional excavator front-end accessory manufacturer
Four modes of operation are strictly prohibited for crushing hammer operations
Oct 30,2024
1. The excavator is not stable to start work
A kind of wrong operation behavior: the excavator is not stable under the situation began to work, this behavior is not worth promoting. Because of this work excavator frame will be repeatedly twisted deformation, long time repeated operation frame will produce cracks, reduce service life.
The correct way to deal with is, in front of the excavator's track whole a mound of soil, so that the excavator is in a stable state, you can carry out normal work.
2. Cylinder rod retracted to the limit for crushing hammer operation
The second more hurt excavator operation behavior is: as shown in the figure, the excavator's hydraulic cylinder telescoping to the end of the position, digging operation, in this case the work of the cylinder, the frame will produce a larger load, the impact of the bucket teeth, the impact of the various axle pins, which may cause internal damage to the cylinder, but also affect the other hydraulic components.
3. Floating the rear of the track to do crushing hammer operation
The third wrong operation behavior is: use the back of the excavator body floating force for crushing hammer operation. When the bucket is separated from the rock and the vehicle body falls, a large load is generated on the bucket, counterweight, frame, slewing bearing, etc., which can easily cause damage. The track floating operation as shown in the picture is very hurtful to the excavator.
Simply put, when the rear part of the track floats to do excavation work, the total force of oil pressure and body weight is applied to each pin and its edge part, and the bucket, so it is easy to cause cracking of the working device. The fall of the track will also produce a large impact on the rear part of the counterweight, which may cause deformation of the main frame and breakage of the slewing bearing ring.
4. Use the traction walking force to move large objects and do the crushing hammer work.
After zui told you a kind of hurt excavator operation behavior is: excavator in the crushing hammer work, with the walking traction to move large objects and crushing hammer brazing rod as a pry bar operation, the work device, pin shaft, frame, bucket will have a more vigorous role in the above, affecting the service life of these parts, so try not to do so.
Summary: We have a further understanding of the prohibited operating behavior of the excavator, and hope that you can use the correct operation when driving the excavator to reduce the damage to the excavator.
