Modern Palfinger cranes (from 2005 onward) use the , Paltronic 100 , or HP HPLS control systems. When the system detects a voltage irregularity, out-of-range sensor value, or communication break, it locks the crane’s hydraulic functions.
: The codes are usually very specific (e.g., identifying exactly which solenoid valve is drawing too much current). palfingercranemanualerrorcodes
Use only if the crane is completely frozen and the display is off. Modern Palfinger cranes (from 2005 onward) use the
To minimize the occurrence of Palfinger crane manual error codes and ensure optimal performance, follow these best practices: Use only if the crane is completely frozen
| Error Code | Description | Immediate Action | | :--- | :--- | :--- | | | LMI (Load Moment Indicator) data invalid | Restart system. If reoccurs, check the LMI cable for cuts. | | 413 | Boom extension sensor error | Pull the boom out 1 meter and retract fully to "teach" the sensor. | | 425 | A2B (Anti-Two-Block) active or wire break | The hook is at the tip OR the rope has snapped the switch wire. | | 444 | Angle sensor out of range (below -5° or above 85°) | Replace the absolute encoder at the boom pivot pin. |
| Symptom | Most likely error code | Check first | |---------|------------------------|--------------| | No function, remote connected | E 03, E 31 | Receiver fuse, ECU power | | Crane moves slowly | E 20, E 21 | Oil level, cooler fan | | Boom won’t lift heavy loads | E 10 | Pressure sensor, overload setting | | Stabilizer light stays red | AL 32 | Stabilizer microswitch / proximity sensor | | Display blank but remote works | – | Backlight fuse or display ribbon cable |
