Backhoe dipper arm dropping is when the backhoe's dipper arm suddenly drops during work operation. This situation can affect work efficiency as the rapid descent of the boom may trouble the driver and even lead to safety accidents.
Reasons for dipper arm dropping
1. Hydraulic oil quality: Poor hydraulic oil quality can cause the issue, especially if the excavator is in a cold start condition.
2. Damaged or aging oil seals: A damaged oil seal in the cylinder can cause a leak, which can cause the boom to drop to some extent.
3. Failure of safety valves: A clogged or worn safety valve spool controlling the dipper arm can also cause this condition.
