The problems of excavator walking deviation mostly occur in the situation of old machines, bad working environment, large uneven slopes, etc. In the previous article, the editor has also analyzed the causes of failures and treatment methods for everyone from all angles.
Excavator model: Hitachi ZX870H-3 excavator
Reasons for Hitachi excavator walking deviation:
1. There is a problem with the hydraulic circuit or valve
2. Blockage of oil circuit or valve
3. The pressure of the hydraulic pump is not suitable
4. Walking motor failure
5. The difference in driving force provided by the left and right walking motors is relatively large
6. The chassis itself has problems
7. The parallelism of the left and right track beams is not good
Hitachi excavator walking deviation detection method:
1. Check the walking pump
2. The flow rate of the two groups of pumps will be different
3. Check the pressure of the hydraulic pump to see if the pressure of the two groups of pumps is the same. If the pressure is different, walking will also deviate.
