Study Distribusi Daya Hidraulik pada Attachment Excavator KOMATSU PC 200(Studi Kasus: PT.ANEKA DARMA PERSADA)

The operation of an excavator requires a variety of operations from attachments. Excavator attachment operations require hidraulik power. An excavator attachment consists of a bucket, arm, boom, swing motor, and travel motor. Basically the hydraulic system is a system of transfer and control of force and movement with liquid fluid. Pressurized oil from the pump is distributed to various attachments. This study aims to determine the hydraulic power distribution on the excavator attachment To find out the power that occurs requires a large flow rate and pressure on the attachment. Power in units of kW, flow rate in units of l / minute, and pressure in units of N / m2. The amount of power that occurs later is compared to the available power. The power that works on the excavator attachment consists of power from the pump hydraulic of 277.76 kW. The hydraulic pump power is then distributed to the attachment which includes hydraulic swing motor power of 35.52 kW, Travel Motor power of 32.24 kW, Cylinder Boom power of 45.962 kW, Cylinder Arm power of 26.6 kW, and Cylinder bucket power of 22,878 kW. The power used in the attachment is 152.282 kW or about 58.7% of the pump's hydraulic power. Keywords: excavators, hydraulic power, attachments
