Liebherr Fixed Slewing Cranes

Fixed slewing cranes are a space-saving material handling solution that copes well with special infrastructure requirements. The LFS series is based on The series of Liebherr fixed slewing cranes (LFS) is particularly suitable for harbours with restricted space. In Indonesia, our Liebherr fixed slewing cranes LFS 180 have been in operation since 2009, particularly in the area of coal handling. When stress levels on the ground have to be kept low and space in the harbour is limited, an LFS is the preferred choice. The crane series is based on the market-leading mobile harbour crane concept from Liebherr. Instead of a rubber tyre undercarriage, the LFS is mounted on a permanently-installed base pillar. This reduces the amount of space required and ensures high productivity rates from the mobile harbour crane range at the same time.

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
