This project is based on the design of industrial hydraulic forklift circuit in AUTOMATION STUDIOTM simulation software which consists of three sections: 1) Hydrostatic power steering. 2) Tilt cylinders. 3) Mast cylinder. The details of each section is described as follows: 1) Hydrostatic power steering: The power steering unit is of Char-Lynn® steering control unit (SCU) of series 5 using metering unit for PID feedback control. 2) Tilt cylinders: These are each designed and tested for 4000 kg static and dynamic load, for an extension and retraction time of 3 sec. 3) Mast cylinder: It is tested for static and dynamic load of 4000 kg for extension and retraction time of 5 sec. The purpose of flow divider is also being studied here. Result shows that the new design is safe to use under working conditions.
