Condition (upgraded and rebuilt in 2003):

Description of major refurbishment work done to the crane in 2003.:

1) Complete crane structure, including boom, A frame and slewing column were shot blasted and re-painted.

2) New machinery house and cab were installed.

3) Complete new electrics were installed including new PLC (Litronic), Load monitoring system, cabling and electric motors.

4) Complete new hydraulic system (Pumps, motors, valves, hoses etc.)

5) 2 x new tugger winches installed.

6) New auxiliary hoist winch installed.

5) 4 new Luffing gearboxes

6) All 6 slewing gearboxes overhauled.

7) All sheaves were replaced

8) All coolers (gear oil, hydraulic oil) were installed.

9) Slew ring was overhauled by manufacturers Roth Erde.

10) Hooks were overhauled by manufacturer Hinrich Mohr

11) Slip rings were overhauled

Crane was re-installed and commissioned by Liebherr. Then certified by Lloyds.


The crane load control system was upgraded to EU Standard EN 13852-1 in 2009. The crane was last time certified by LRS in Sept. 2011.


The crane is a well maintained machine in very good condition with excellent performance record.

The crane has counters on each function recording actual operating hours, see below:

Main motors approx – 1200hrs

Slew – 307 hrs

Main hoist – 75 hrs

Aux hoist - 235 hrs

Luff – 310 hrs

Tugger 1 – 320 hrs

Tugger 2 – 67 hrs


The above hours have been recorded since the cranes major overhaul back in 2003, all evident on the crane software and the Platform Maintenance Management System. This should be sufficient evidence that there should be no requirement to replace any major components such as slew bearing, winch motors, pinions, bearings, etc... The crane ropes would have to be replaced. In addition to the above the crane would also come with a full upgrade package for emergency operation supplied by Liebherr, however, this kit was never installed to the crane.

Diameter of pedestal: 5020 mm Ø

Wall thickness of pedestal: 40 mm

Bolt hole circle C - C: 4745 mm Ø
Weight: 23600 kg (pedestal adaptor)
