“PALFINGER’s telescopic boom cranes are based on a pedestal slewing design with hydraulic cylinder luffing. The boom extension is a telescopic inner section that enables a more flexible and wider…”

Inspection

Inspector Detail

Common issues

  • Hydraulic cylinder seal leakage on boom extension/luffing cylinders
  • Wire rope wear or corrosion on the hoist winch
  • Slew bearing or gear wear causing play or noise
  • Load moment limiter sensor drift or fault
  • Hydraulic hose chafing/wear at boom articulation points
  • Structural fatigue cracking at boom welds or pivot points on older units
  • Remote control/PLC fault causing loss of function or erratic operation

Inspection checklist

  • Visual check of the boom structure for deformation, cracks or corrosion at welds
  • Check hydraulic system for leaks, oil level and filter condition
  • Function test of the load moment limiter and overload cut-out
  • Inspect hoist wire rope for wear, broken wires and lubrication
  • Check slew bearing bolt torque and gear backlash
  • Test all limit switches (luffing, slewing, hoist up/down)
  • Check hook block, safety latch and swivel for wear
  • Confirm emergency stop and remote control function
  • Review the last statutory thorough examination/load test certificate

Service intervals

Hydraulic oil sample/changesample every 6-12 months, change per maker recommendation or oil condition
Wire rope inspectionbefore significant lifts, and formally at least every 3 months
Thorough examination (statutory)annually, per flag/class lifting appliance requirements
Load test (proof load)at commissioning, after major repair, and typically every 4-5 years per class interval
Slew bearing/gear lubricationper maker schedule, typically weekly to monthly

Typical wear limits

Hoist wire roperenew per class/ISO 4309 discard criteria (broken wires, diameter reduction, corrosion) - confirm against the wire rope certificate, not a fixed figure
Hydraulic cylinder rod conditionrenew or re-chrome on visible scoring that causes seal leakage - assessed per inspection, no generic figure

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

  • Hydraulic cylinder seal kits for luffing, telescoping and slewing functions
  • Hoist wire rope of the correct diameter/construction
  • Hook block with safety latch
  • Load moment limiter sensor/pressure transducer
  • Hydraulic filter elements
  • Slew bearing/gear grease and seals

Safety

  • Suspended load hazard - exclusion zone required under the boom during operation
  • Hydraulic system stored pressure - isolate and relieve before maintenance
  • Overload risk if the load moment limiter is bypassed or miscalibrated
  • Working at height on the boom/structure during inspection
  • Crush hazard at the slewing base and boom articulation points

Class survey

Lifting appliances require an annual thorough examination and periodic load test under class/flag lifting gear rules; the load moment limiter function test and the wire rope/sling register are typical items class will check.

Estimated lifetime: Marine deck cranes of this class are typically designed for 15-20+ years of service with periodic hydraulic overhaul and structural survey; duty-cycle and load-test history are more meaningful than a running-hour figure

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
