Analisa Mekanisme Kerja Hidraulik Pump Pada Mixer Truck (Studi Kasus: Pt. Tugu Beton Semesta Abadi Semarang)

Operating a Tank Mixer requires hydraulic power which consisting of Main Pump Hydraulic and Main Pump Motor. Basically a hydraulic system is a system that control of forces and movements fluid with liquid. Pressurized oil from the pump is distributed to various kinds of attachments. This study is to determine the distribution of hydraulic power in Tank Mixer Trucks. To find out the power that occurs requires a large flow rate and pressure on the hydraulic. Power in units of kW, flow rate in units of 1 / min, and pressure units in N/m2. The amount of power that occurs then compared to the available power. The power generated by a Varable Displacement Pump is 79,152 kW. And the power generated by the pump is then distributed to the attachment of 30,600 kW. The total amount of power distributed to the Hydraulic Gear Box is 30,600 kW. Then the power used is 38.6% of the Hydraulic Pump power. Keywords: mixer truck, hydraulic power
