Studi Cara Kerja Komponen Sistem Hidrolik Excavator

One of the heavy equipment in the industrial world is an excavator. This heavy equipment, better known as the backhoe, is used to dredge mining materials, such as coal. The main components of the Excavator are Attachments (Boom, Arm and Bucket). To keep the Excavator functioning properly during the operation process, Preventive Maintenance is needed. Hydraulic Cylinder functions as a system for moving work equipment. This analysis aims to determine the types of maintenance in Hydraulic Excavators. The inspection procedure is carried out by performing a performance test consisting of a pressure test on the hydroulic system. Visual inspection was also carried out on hydraulic hose, control valve, hydraulic filter, hydraulic pump, hydraulic cylinder. Next is Preventive Maintenance, which is the implementation of daily, weekly, monthly and annual maintenance work. In daily maintenance, inspection will be carried out, check all lubrication and perform service. Weekly maintenance is carried out every 60 working hours. Monthly maintenance is carried out every 250 working hours, while annual maintenance is carried out every 2500 working hours. The operation of the Excavator unit must be in accordance with the Manual Book. So that the service life of the unit along with the excavator components is in accordance with its life time
