Common failures & inspection points

Wire rope wear: diameter reduction >10% (natural fibre core) or >5% (steel core), wire breaks in groups, kinks, waves, twists, corrosion, pitting

Visual daily inspection per ISO 4309:2017; caliper for diameter; magnetic inductive inspection (MRI) for suspected internal damage; inspection points: drum anchorage, loading, deflection over sheaves, loaded rope sections

Slewing ring: sealing system worn (leaks, contaminated lubrication), tooth wear (check engagement), bearing clearance, vibrations, temperature increase

Visual inspection for lubricant leakage; check seals for wear and contamination; vibration and temperature monitoring; overhaul by qualified Liebherr service with specialized equipment if needed

Hydraulic system: pressure loss, leaks at cylinders/pipes, hydraulic fluid contaminated or oxidized, valve and control function impaired

Drucktest (Pressure Test) gegen spezifizierte Solldrücke; Sichtprüfung auf Flüssigkeitsverluste; Ölprobenanalyse (Condition Monitoring); Funktionsprüfung aller Hubfunktionen (Heben, Schwenken, Luffing)

Hook/Hook-block: cracks, plastic deformation, wear on running surfaces, notches or scratches, damage to load deflection surfaces

Visual surface inspection for surface cracks and deformation; NDT inspection (X-ray/MRI) at critical hooks for internal damage; load test: ~25% above rated load capacity; inspection of hook locking and wear marks

Steel structure / boom / jib: corrosion, surface cracks (especially at welds and load introduction points), plastic deformation, welded repairs

Surface rust and corrosion by visual inspection; NDT inspection (ultrasonic, X-ray) at critical welds; dimensional check of geometric tolerances; overhaul by Service Centre Steel with welding/structural analysis if required

Electrical / control (Litronic system): cable insulation faults, connectors/contacts oxidized or corroded, malfunction of control systems, overload/underload

Visual inspection of all electrical connections for corrosion in saltwater environment; functional test of overload protection and indicators; continuity test of critical circuits; lithium battery/accumulator condition check on electro-hydraulic systems
