ANALISIS PERAWATAN HYDRAULIC CRANE UNTUK MENUNJANG KINERJA BONGKAR MUAT DI MV.BULK JAVA

Abstract

Hydraulic cranes are the main equipment used to support smooth loading and unloading activities on board ships. Optimal hydraulic crane performance is essential to ensure that loading and unloading operations run effectively, safely, and efficiently. However, during sea practice on MV.Bulk Java, several problems were identified, including the failure of the Steel Plate slewing brake and inadequate maintenance of the hydraulic crane, especially on the hose and hydraulic oil filter components. These damages disrupted crane operations and hindered loading and unloading activities. This study aims to determine the causes of Steel Plate slewing brake failure and the inadequate maintenance of the hydraulic crane on MV.Bulk Java. The research used a descriptive qualitative method with data collection techniques through observation, interviews, documentation, and literature study. The results showed that the failure of the Steel Plate slewing brake was caused by delays in spare part replacement and inadequate periodic inspections. In addition, the lack of routine inspections on hoses and filters caused hose leakage and the accumulation of metal particles and dirt in the hydraulic oil tank. Efforts to overcome these problems were carried out through spare part replacement, improving routine maintenance, and consistently implementing preventive maintenance to prevent recurring damage and support smooth loading and unloading operations on board the ship.
