IHI-Wuhan Deck Crane, troubleshooting & change-out IHI hoist motor HVGL-DSS

 

ALATAS Singapore received a distress call form a stricken bulker, carrying out cargo operation in Singapore waters, deck crane 4 was losing performance and lo longer could lift the full grab. ALATAS arranged an emergency crane service and attended overnight to investigate the hoisting vibrations. As it turned out, the hydraulic hoist motor, type HVLG-DSS was found damaged, as evident by Teflon & metal parts in the hydr. Filter insert.
A replacement  motor, p/n 5110417 R, was supplied on urgent basis ex ALATAS stock and installed. The crane then was successfully load tested with the full grab and the crane was handed over for cargo operation late night on the next day.

Another successful service attendance by ALATAS, made possible due to competent crane engineers and a well-equipped crane spare parts stock.
