Alatas - Luffing winch removal, overhaul and installation
ALATAS Offshore crane service in Aberdeen was called out to troubleshoot a Liebherr Offshore Crane, type BOS 50/800D.
The crane suffered a failure of the luffing winch, the planetary gears had seized.
Alatas mobilized a team of specialist Liebherr Engineers, complete with tools & equipment to dismantle the rope winch from the crane and arrange transport from the platform at Offshore North Sea to ALATAS Engineering Ltd, a workshop specialised in the repair of Zollern Rope Winches and Planetary Gearboxes and specialised in the supply of Zollern gearbox spare parts.
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 utilized 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.
