Alatas Singapore - CBW Crane Luffing Cylinder Hinge Bearing Repairs
The geared bulker is equipped with 40T Liebherr CBW 32(40)/28 type deck cranes, suitable for grab operation with a SWL of 40T in hook mode and 32T in grab mode.
The heavy duty grab operation took its toll and the hinge bearing assembly of the luffing cylinder foot bearing arrangement had worn out prematurely. Not only the bearing had collapsed, but also the heel pin got damaged and the foot pin housing had deep wear marks too.
ALATAS specialized afloat repair team was called in to replace the heel pins, foot pin bearings and bushes. Alatas mobilized engineers, staging, rigging gear and hot work to gauge out the damaged & seized pins. Our experienced crane engineers worked around the clock, and competed the complex crane repairs in the shortest possible time.
Required crane spare parts were supplied ex Alatas parts stock, i.e. cylinder bearings, sleeves, bushes, plastic spacer rings, including new hollow boom heel pins, as per Liebherr Id. Nr. 918508714
