Alatas Offshore Crane Service in Aberdeen was called out to troubleshoot a Liebherr BOS 50/800D and to carry out a Zollern winch overhaul. The offshore crane had suffered a failure of the luffing winch, the planetary gears had seized.
Alatas mobilised a team of specialist Liebherr engineers along with tools and equipment to dismantle the rope winch from the crane.
Afterwards, they would arrange transport from the platform stationed in the North Sea to Alatas Engineering Ltd, a workshop specialising in the repair of Zollern rope winches, planetary gearboxes and able to supply Zollern gearbox spare parts.
Transport of Equipment to our Workshop
The luffing winch was stripped down, assessed and rebuilt with original Zollern spare parts to a condition like new.
The rope winch was dynamically tested on our dynamic rope winch test stand and a detailed repair report, dynamic test report and a winch repair quality certificate were issued with the repaired rope winch.
Our Offshore Crane Service team was called upon again to install the Liebherr luffing winch, reeve wire ropes, carry out limit switch adjustments and crane function testing before handing the crane over to operations.
