Check the cables leading to the sensor on the boom or slewing gear for damage or disconnection.
: Remove the small access cover on the base of the crane. Look inside to find a screen that shows a four-digit code automatically, like 25.14 .
Ensure the blind plug was not left uncoupled when removing the jib. Electrical Levels Pressure Transducer Signal Exceeds 19.7 mA ( U230 ). Short circuit in cable array or defective transducer unit. 24.01 Positioning Main Boom Angle Encoder Disconnected.
While there are numerous error codes specific to Palfinger cranes, here are some common ones: palfingercranemanualerrorcodes
Found on older or standard models (e.g., Paltronic 50/100).
Note whether the code is or flashing . If it flashes, record both the main code (with a dot) and the additional code (without a dot). Also check the colour and behaviour of the LED capacity strip (green, yellow, red).
While exact code definitions can vary slightly depending on your specific crane model, Paltronic generation, and configuration, the following codes represent the most frequent issues encountered in the field: 1. Overload Protection System (OSK / Standard Overload) Check the cables leading to the sensor on
While specific codes vary by model year, Palfinger uses a logical structure across their manuals. Here is a generalized breakdown based on standard Palfinger diagnostic logic:
Check the primary power supply to ensure the truck batteries are delivering stable voltage (usually 24V). Inspect the main wiring harnesses connecting the radio receiver to the main valve block for pinches or cuts. 5. Stabilizer / Outrigger Interlock Faults (E40 Series) Code Range: E40, E41, E42.
Use the manual OLP button to carefully lower the lift cylinder. Crane Stability HPSC Stability Limit Reached. Ensure the blind plug was not left uncoupled
Most issues come from the electronic safety systems like the . This list shows the most common numbers you will see during work. Error Code What It Means Why It Happened How to Fix It 81 Overload Limit Reached The crane is lifting too much weight. Move the boom to reduce the load weight. 44 / 42 Broken Transducer Connection The wire to the pressure sensor is broken. Check the sensor plugs and fix bad wires. 20 / 21 High Pressure Sensor Signal There is a short circuit in the sensor cable. Swap plugs to test or replace the sensor. 31.00 Support Control Overload Too much force is pushing down on the outriggers. Change your lift angle to balance the weight. 33.00 Boom Angle Limit The arm is raised too high, past 85 degrees. Lower the crane arm safely using your controls. 84 / 82 Internal System Memory Error The internal system board cannot read its data. The main computer board needs repair. 🔍 Three Quick Troubleshooting Steps
