Speed Control System Research on Hydraulic Torque Forklift

Abstract:

By researching the characteristics of hydraulic torque forklifts, developed a device which achieved inching function. It can detect position of the handle, using Delta PLC controlled stepper motor driven screw movement, to achieve the control of the engine speed, and modify the control parameters via touch-screen on-site commissioning, to achieve a truck at idle operation, through the manipulation of the handle can Smooth and stable pan, lift or tilt operation, making operation more convenient forklift and reduces the operator's labor intensity, a high value market applications.
