For marine crane, abrasion of the lining would cause the drum to slip and the troubles in winding the wire ropes. The frequent use of clutch leads to more abrasion of the lining. Serious abrasion would cause damage to the clutch shoe.
As the movements of slewing and jib luffing are operated with the hydraulic device, its malfunctions cause troubles in these movements. Cleaning of the suction filter and Refueling oils are also required other than replacement of the line filters and return filters
Zinc for Oil Cooler
The swivel supplies cooling water to the crane. Lack of maintenance may cause leakage of cooling water due to corrosion. Applying greasing frequently is required
