NON-DESTRUCTIVE TESTING OF HYDRAULIC CYLINDER EXCAVATOR BUCKET AND FAILURE ANALYSIS

Abstract

The bucket cylinder is one of the important components in the front attachment of the excavator. The component is combined with a hose that flows the hydraulic oil flow from the hydraulic pump, and control valve to the bucket cylinder, which moves the bucket on the excavator. If the bucket cylinder does not work according to standards, a malfunction will occur which causes problems with the excavator so that damage occurs to the inner parts components. The research method used is an observation of the damaged bucket cylinder components, after observing the bucket cylinder check, interviewing the excavator operator, and checking using a dye penetrant, the bucket disassembly process is carried out to determine the condition of the bucket cylinder components to make it easier to observe the damage that occurs to the bucket cylinder, then the bucket cylinder component disassembly process is carried out then the inspection process is carried out using dye penetrant and hydraulic oil sampling to make it easier to collect data on the damage that occurs to the bucket cylinder components after the inspection of the damaged parts is carried out, repairs and replacement of spare parts with new ones so that the bucket cylinder can be reused.
