The hydraulic system of a mobile crusher is of critical importance: early diagnosis prevents costly downtime. Early faults are indicated by unusual noises, minor oil leaks and a slowdown in the operating cycles of the working components. At the initial stage, you can check the oil level, clean the filters and tighten the connections yourself. In the event of severe leaks, pressure surges, etc., call out a technician immediately; do not attempt to dismantle the system yourself.
The hydraulic system of a mobile crusher functions like the machine’s circulatory system; early diagnosis of faults helps to avoid costly downtime, and if irreparable leaks, sudden pressure drops or unusual noises in the pump occur, you should contact professional technicians immediately.
Take note of any unusual noises whilst the system is running, minor oil leaks on the housing, or a slowdown in the lifting or compression cycles of the working components — these are the first signs that the hydraulic system is beginning to malfunction, and they should not be ignored, even if the crusher remains largely operational.
To begin with, you can check the level and condition of the hydraulic oil yourself, clean any dirt from the filters and tighten any loose pipe connections; if these measures do not resolve the issue, you should not dismantle any system components yourself without the appropriate tools and expertise.
If, following basic checks, there are still sudden pressure surges in the system, severe oil leaks, deviations of the working components from their set trajectories, or regular activation of the safety valves — these are signs of serious internal faults in the pump, hydraulic motors or directional control valves, requiring professional diagnosis and repair on a specialised test bench.
