Reclaimer rake hydraulic system is mainly composed of double vane pump, proportional reversing valve, electromagnetic relief valve and hydraulic cylinder. Through the reciprocating movement of the hydraulic cylinder, the taking action of the reclaimer was realized. The equipment cost and maintenance cost are higher because proportional reversing valve in the system using. Using AMESim software, the hydraulic system of the reclaimer rake was optimized in order to reduce the cost of equipment.
