Abstract

The purpose of this project was to design a new lifter system for a 6x6 oil palm fruit bunch utility transporter. In order to achieve this goal, theoretical and simulation analysis were conducted by using fluid power formula and FESTO FluidSim Software. The main parameter that was observed and compared included hydraulic cylinder and rod cylinder diameter, extension and retraction velocity, power consumed and efficiency of the volumetric flow pump. The two types of model were used in simulation which were single and dual hydraulic open circuit system. They were analyzed by varying the diameter of cylinder piston and rod piston cylinder diameter. It consist of 10cm, 13cm, 15cm and 17cm for rod piston diameters. Meanwhile for cylinder piston diameters were 13cm, 15cm, 17cm, and 19cm. The results obtained from theoretical calculation showed that double cylinder has higher volumetric efficiency which was 70.83% and single cylinder slightly lower for 68% efficiency. These findings verified that double cylinder of hydraulic model was the most practical in consuming less power by the motor but higher volume flow rate efficiency. Then for simulation result, it had slight difference in term of extend velocity and retract velocity values compared with theoretical result. Based on simulation, the highest extend velocity was 0.085 m/s while theoretical was 0.107 m/s with 20.56% deviation. Besides the highest retract velocity from simulation was 0.145 m/s while theoretical was 0.262 m/s with 44.66% deviation. The detail specification of the actuator, pump unit, directional valve, tilting angle, motor, and material of bucket were achieved from current product and previous researches data. All of those information were the key to complete this project. Hopefully, more research about 6x6 palm oil fruit bunch utility transporter will be conducted in a future because palm oil plays a major contribution in increasing Malaysia’s economy. This approach might improve the productivity of palm oil industry due to the less manpower consumes to complete the loading and unloading the palm oil fruit bunches in a short time
