The Bulker is equipped with 4 deck cranes, make Liebherr, type CBW 32(40)/28LS with a capacity of SWL 40T in hook operation and SWL 32T in grab operation. The grab in use is a radio remote controlled grab, make SMAG Peiner, type EGF 24.0-1.25-12000.
The crew reported noise emanating from the luffing cylinder bearing when operating the crane boom with a fully loaded grab. An Alatas Liebherr crane engineer was called to investigate and determined the problem to be a damaged luffing cylinder foot hinge bearing assembly.
Alatas arranged it's experienced afloat repair team, scaffolding, tools and equipment to carry out the cylinder foot bearing change out at anchorage.
As so often with similar type of failures, the failed Spherical Bearing also caused irreparable damage to the hinge pin. The pin therefore had to be gauged out and replaced new as well.
As these cylinder bearing failures occur more often, ALATAS keeps stock of complete Cylinder Pivot Bearing Repair Kits, Liebherr Part Nr. 918508714. Each kit consists of the maintenance free spherical bearing, hollow pin, bushes and accessories.
